abstract = "A new algorithm called Mersenne Twister (MT) is
proposed for generating uniform pseudorandom numbers.
For a particular choice of parameters, the algorithm
provides a super astronomical period of $2^{19937} - 1$
and 623-dimensional equidistribution up to 32-bit
accuracy, while using a working area of only 624 words.
This is a new variant of the previously proposed
generators, TGFSR, modified so as to admit a
Mersenne-prime period. The characteristic polynomial
has many terms. The distribution up to $v$ bits
accuracy for $1 \leq v \leq 32$ is also shown to be
good. An algorithm is also given that checks the
primitivity of the characteristic polynomial of MT with
computational complexity $O(p^2)$ where $p$ is the
degree of the polynomial.\par
We implemented this generator in portable C-code. It
passed several stringent statistical tests, including
diehard. Its speed is comparable to other modern
generators. Its merits are due to the efficient
algorithms that are unique to polynomial calculations
over the two-element field.",

Certain randomness properties of AES are of vital
importance for its security. At the same time, these
properties make AES an interesting candidate for a fast
nonlinear random number generator for stochastic
simulation. In this article, we address both of these
two aspects of AES. We study the performance of AES in
a series of statistical tests that are related to
cryptographic notions like confusion and diffusion. At
the same time, these tests provide empirical evidence
for the suitability of AES in stochastic simulation. A
substantial part of this article is devoted to the
strategy behind our tests and to their relation to
other important test statistics like Maurer's Universal
Test.",

first detailed statistical results for AES in the

AES has been evaluated using the NIST package (see NIST
[2001a]). In principle, we consider this type of
testing necessary and valuable. However, up to now, AES
has only been tested using relatively small sample
sizes. Furthermore, the exact test procedure and the
parameters that were used have not been published.
There are no refereed publications on this topic.

4. FINDINGS\par
AES performed very well. The empirical results support
the hypothesis that AES is not only an excellent
cryptographic algorithm, but also a very interesting
nonlinear random number generator for stochastic
simulation.\par
We were unable to find any statistical weaknesses. Most
of the $p$-values were completely uncritical, no
systematic trends popped up in the tests.\par
\ldots{} \par
The results indicate that AES pseudorandom numbers are
indistinguishable from real random numbers with respect
to bit-vectors up to length 16 and with respect to the
distribution of 0's and 1's in bit-vectors up to length
256.\par
From the results for DIFF we conclude that AES is able
to compensate for an extreme lack of 1's in the
plaintext, and hence provides excellent diffusion in
this case. The results for KCOUNT provide some
confidence that the key schedule used for generating
the internal keys for the encryption rounds in AES does
a good job. Similar keys do not yield correlated output
sequences.''",

abstract = "Random numbers with high cryptographic quality are
needed to enhance the security of cryptography
applications. Software heuristics for generating
empirically strong random number sequences rely on
entropy gathering by measuring unpredictable external
events. These generators only deliver a few bits per
event. This limits them to being used as seeds for
pseudorandom generators. General-purpose processors
feature a large number of hardware mechanisms that aim
to improve performance: caches, branch predictors,
\ldots{}. The state of these components is not
architectural (i.e., the result of an ordinary
application does not depend on it). It is also volatile
and cannot be directly monitored by the user. On the
other hand, every operating system interrupt modifies
thousands of these binary volatile states. In this
article, we present and analyze HAVEGE (HArdware
Volatile Entropy Gathering and Expansion), a new
user-level software heuristic to generate practically
strong random numbers on general-purpose computers. The
hardware clock cycle counter of the processor can be
used to gather part of the entropy\slash uncertainty
introduced by operating system interrupts in the
internal states of the processor. Then, we show how
this entropy gathering technique can be combined with
pseudorandom number generation in HAVEGE. Since the
internal state of HAVEGE includes thousands of internal
volatile hardware states, it seems impossible even for
the user itself to reproduce the generated sequences.",
acknowledgement = ack-nhfb,
annote = "From the article: ``On current PCs and workstations,
the HAVEG algorithms collects several tens of thousands
of empirically strong random bits, on average, per
every operating system interrupt, that is, HAVEG is
three to four orders of magnitude more efficient than
previous software entropy gathering
techniques.\par
\ldots{}\par
\ldots{} on all the target platforms of HAVEGE in 2002
[Seznec and Sendrier 2002], the HAVEG algorithm
illustrated in Figure 1 allows to gather at least
8K--64K random bits in average per operating system
interrupt (from 8K on Itanium/Linux to 64K on
Solaris/UltraSparc II). That is, at least three to four
orders of magnitude more than the `entropy' gathered by
previously available entropy-gathering
techniques.\par
\ldots{}\par
In average on Pentium III, 920 million $\pm5\%$ cycles
were needed to collect 32 Mbytes of random numbers,
while on the UltraSparc II, 500 million $\pm5\%$ cycles
were sufficient. This throughput is in the same range
as the throughput of standard pseudorandom number
generators.''\par
Thus, it seems that this algorithm deserves careful
consideration for use in {\tt /dev/random} and {\tt
/dev/urandom} pseudodevices in Unix systems, since the

abstract = "The inversion method for generating nonuniform random
variates has some advantages compared to other
generation methods, since it monotonically transforms
uniform random numbers into non-uniform random
variates. Hence, it is the method of choice in the
simulation literature. However, except for some simple
cases where the inverse of the cumulative distribution
function is a simple function we need numerical
methods. Often inversion by ``brute force'' is used,
applying either very slow iterative methods or linear
interpolation of the CDF and huge tables. But then the
user has to accept unnecessarily large errors or
excessive memory requirements, that slow down the
algorithm. In this article, we demonstrate that with
Hermite interpolation of the inverse CDF we can obtain
very small error bounds close to machine precision.
Using our adaptive interval splitting method, this
accuracy is reached with moderately sized tables that
allow for a fast and simple generation procedure.",
acknowledgement = ack-nhfb,
annote = "From the article: ``we have written this article to
demonstrate that numerical inversion can be realized in
a simple, accurate and fast algorithm utilizing tables
of moderate size. It has fairly short code and is
implemented in our freely available UNU.RAN library
(see Leydold and H{\"o}rmann [2002]).\par
To test the correctness of an inversion algorithm, it
is not necessary to make statistical tests. It is
enough to compute the maximal and the average $u$-error
$|u - F(x)|$ obtained in a large sample of uniformly
distributed $u$ values.
The generation speed is for all distributions (much)
faster than using iterative methods and about the same
as generating an exponential random variate.''.",

universal nonuniform random number generators. Its key
part is an accurate approximation of a given
probability density from above by a hat function. This
article uses a piecewise constant hat function, whose
values are overestimates of the density on the elements
of the partition of the domain. It uses a sawtooth
overestimate of Lipschitz continuous densities, and
then examines all local maximizers of such an
overestimate. The method is applicable to multivariate
multimodal distributions. It exhibits relatively short
preprocessing time and fast generation of random
variates from a very large class of distributions.",

xorshift random number generators, whose implementation
uses three ``xorshift'' operations. They belong to a
large family of generators based on linear recurrences
modulo 2, which also includes shift-register
generators, the Mersenne twister, and several others.
In this article, we analyze the theoretical properties
of xorshift generators, search for the best ones with
respect to the equidistribution criterion, and test
them empirically. We find that the vast majority of
xorshift generators with only three xorshift
operations, including those having good
equidistribution, fail several simple statistical
tests. We also discuss generators with more than three
xorshifts.",

abstract = "Current software-based microarchitecture simulators
are many orders of magnitude slower than the hardware
they simulate. Hence, most microarchitecture design
studies draw their conclusions from drastically
truncated benchmark simulations that are often
inaccurate and misleading. This article presents the
Sampling Microarchitecture Simulation (SMARTS)
framework as an approach to enable fast and accurate
performance measurements of full-length benchmarks.
SMARTS accelerates simulation by selectively measuring
in detail only an appropriate benchmark subset. SMARTS
prescribes a statistically sound procedure for
configuring a systematic sampling simulation run to
achieve a desired quantifiable confidence in estimates.
Analysis of the SPEC CPU2000 benchmark suite shows that
CPI and energy per instruction (EPI) can be estimated
to within $\pm3\%$ with $99.7\%$ confidence by
measuring fewer than 50 million instructions per
benchmark. In practice, inaccuracy in
microarchitectural state initialization introduces an
additional uncertainty which we empirically bound to
$\pm2\%$ for the tested benchmarks. Our implementation
of SMARTS achieves an actual average error of only
$0.64\%$ on CPI and $0.59\%$ on EPI for the tested
benchmarks, running with average speedups of 35 and 60
over detailed simulation of 8-way and 16-way
out-of-order processors, respectively.",

When applied to the workloads on parallel
supercomputers, we find two stable perpendicular axes
of highly correlated variables, one representing
individual job attributes and the other representing
multijob attributes. The different workloads, on the
other hand, are rather different from one another, and
may also change over time. Synthetic models for
workload generation are also analyzed, and found to be
reasonable in the sense that they span the same range
of variable combinations as the real workloads.
However, the spread of real workloads implies that a
single model cannot be similar to all of them. This
leads us to construct a parameterized model, with
parameters that correspond to the two axes identified
above. We also find that existing models do not model
the temporal structure of the workload well, and hence
are wanting for tasks such as comparing schedulers, and
that the common methodology for load manipulation of

are widely employed to support scalable remote entity
modeling in distributed interactive applications
(DIAs). By employing a form of controlled
inconsistency, a reduction in network traffic is
achieved. However, by relying on the distribution of
instantaneous derivative information, dead reckoning
trades remote extrapolation accuracy for low
computational complexity and ease-of-implementation. In
this article, we present a novel extension of dead
reckoning, termed neuro-reckoning, that seeks to
replace the use of instantaneous velocity information
with predictive velocity information in order to
improve the accuracy of entity position extrapolation
at remote hosts. Under our proposed neuro-reckoning
approach, each controlling host employs a bank of
neural network predictors trained to estimate future
changes in entity velocity up to and including some
maximum prediction horizon. The effect of each
estimated change in velocity on the current entity
position is simulated to produce an estimate for the
likely position of the entity over some short
time-span. Upon detecting an error threshold violation,
the controlling host transmits a predictive velocity
vector that extrapolates through the estimated
position, as opposed to transmitting the instantaneous
velocity vector. Such an approach succeeds in reducing
the spatial error associated with remote extrapolation
of entity state. Consequently, a further reduction in
network traffic can be achieved. Simulation results
conducted using several human users in a highly
interactive DIA indicate significant potential for
improved scalability when compared to the use of IEEE
DIS standard dead reckoning. Our proposed
neuro-reckoning framework exhibits low computational
resource overhead for real-time use and can be
seamlessly integrated into many existing dead reckoning
mechanisms.",

such services, service unavailability events are rare

runtime. Importance sampling (IS) has been applied to
certain instances of such systems, focusing on
single-class and/or homogeneous resource demands. In
this article, we formulate highly available services as
multiresource losstype systems, and we present two IS
methods for fast simulation, extending to multiple
classes and nonhomogeneous resource demands. First, for
the cases in which component failure rates are small,
we prove that static IS using the Standard Clock
(S-ISSC) method exhibits the bounded relative error
(BRE) property. Second, for estimating failure
probabilities due to large capacity or fast service in
systems that have nonrare component failure rates, we
propose adaptive ISSC (A-ISSC), which estimates the
relative probability of reaching each possible state of
system failure in every step of the simulation. Using
A-ISSC, IS methods which are proven to be efficient can
be extended to multidimensional cases, while still
retaining a very favorable performance, as supported by
our validation experiments.",

Any protocols developed for screening and surveillance
and any policy decisions regarding the availability of
CRC resources should consider the nature of the disease
and its impact over time on costs and quality-adjusted
life years in a population. Simulation models can
provide a flexible representation needed for such
analysis; however, the development of a credible
simulation model of the natural history of CRC is
hindered by limited data and incomplete knowledge. To
accommodate the extensive modeling and remodeling
required to produce a credible model, we created an
object-oriented simulation platform driven by a
model-independent database within the .NET environment.
The object-oriented structure not only encapsulated the
needs of a simulation replication but created an
extensible framework for specialization of the CRC
components. This robust framework allowed development
to focus modeling on the CRC events and their event
relationships, conveniently facilitating extensive
revision during model construction. As a
second-generation CRC modeling activity, this model
development benefited from prior experience with data
sources and modeling difficulties. A graphical user
interface makes the model accessible by displaying
existing scenarios, showing input variables and their
values, and permitting the creation of new scenarios
and changes to its input. Output from the simulation is
captured in familiar tabbed worksheets and stored in
the database. The eventual CRC model was conceptualized
through a series of assumptions that conformed to
beliefs and data regarding the natural history of CRC.
Throughout the development cycle, extensive
verification and validation calibrated the model. The
result is a simulation model that characterizes the
natural history of CRC with sufficient accuracy to
provide an effective means of evaluating numerous
issues regarding the burden of this disease on
individuals and society. Generalizations from this

infrastructure servicing billions of end-users
world-wide. Ongoing studies of the Internet's
operations show that data loss and increased latency
are occurring due to weaknesses in its interdomain
routing protocol, BGP. Many solutions have been
proposed, but few have experienced widespread adoption.
Both the delayed discovery of the protocol's
shortcomings, and apathy for its proposed solutions,
are partially due to inadequate testing practices.
Internet interdomain routing technologies are not
evaluated at appropriate scale. Better testing is
suggested, which incorporates the specification of
large-scale experimental topologies. This is necessary,
as BGP performs the distributed operation of
interdomain routing across the thousands of networks
composing the Internet. However, only small to
moderately sized topologies can be currently
accommodated by today's testing platforms.\par
A modeling methodology based on path preserving
scale-down is proposed to extend the topological scale
of interdomain routing experimentation. A given
Internet topology is reduced in terms of its autonomous
systems (ASes) using a combination of Gaussian
elimination and several graphical heuristics. The
interdomain routing paths generated by BGP on this
reduced topology are also preserved. Path preservation
keeps the length, composition, and ordering of these
routing paths unchanged. When the routing paths guiding
Internet traffic among ASes are preserved across the
size reduction, the large-scale traffic engineering
induced by BGP can be estimated at much lower scales.
Internet data losses due to certain inappropriate
interdomain routing behaviors can be identified. As an
example, a persistent multiple origin autonomous system
(MOAS) conflict is characterized over a topology
containing 8826 ASes. It is shown that this problem's
large-scale characterization can be obtained using
scale-down models that are 70\% smaller, and thus more
accommodating to common testing platforms (e.g.,
simulation and networking testbeds).",

abstract = "This article reports on the application of a framework
used to model, simulate and visualize the 3D structure
of astrophysical wind volumes. The modeling methodology
is similar to multidirectional medical tomography in
that the spatial structure of an extended target can be
reconstructed from a sequence of images obtained by
scanning that target from several directions. Even
though the controlled environment realized in
diagnostic radiology cannot be replicated in the study
of astrophysical phenomena, strong candidates for
astrophysical tomography do exist in hot, close double
stars locked in orbits around a common center of mass.
As the Keplerian orbit is traced out, the geometry
presented to the observer varies so that each star
constitutes an analyzer upon its companion's wind and
probes its structure. Since these targets are too far
to be resolved spatially, we study and model the UV
spectral lines of prominent wind ions, which scatter
photospheric UV light so that line shapes vary as the
stars revolve and as inhomogeneities form, propagate,
and evolve in the composite wind. The framework
presented is applied to two hot close binaries near the
applicability limits of the discussed methodology. Two
novel custom-made tools that aid the analysis of the
spectra and the visualization of the results are also
presented. The first of these, the {\em Spectrum
Analyzer and Animator}, automates the derivation of
light curves from the observed spectra and the
generation of synthetic binary wind-line profiles,
which reproduce the morphologies and variabilities of
the observed wind profiles. After the composite wind
structure of a binary has been recovered, the second
tool, the {\em Binary 3D Renderer\/} --- also authored
in IDL --- aids the visualization of the results by
simulating the motion of the system (stars, winds and
wind-interaction effects) around the binary's center of
mass. The {\em Binary 3D Renderer\/} thus repackages
the end product of a lengthy physical modeling process
to generate physically sound, realistic multimedia
content and increase the effectiveness and
communication impact of the research results.",

abstract = "As functionality is added to an aging piece of
software, its original design and structure will tend
to erode. This can lead to high coupling, low cohesion
and other undesirable effects associated with spaghetti
architectures. The underlying forces that cause such
degradation have been the subject of much research.
However, progress in this field is slow, as its
complexity makes it difficult to isolate the causal
flows leading to these effects. This is further
complicated by the difficulty of generating enough
empirical data, in sufficient quantity, and attributing
such data to specific points in the causal chain. This
article describes a framework for simulating the
structural evolution of software. A complete simulation
model is built by incrementally adding modules to the
framework, each of which contributes an individual
evolutionary effect. These effects are then combined to
form a multifaceted simulation that evolves a
fictitious code base in a manner approximating
real-world behavior. We describe the underlying
principles and structures of our framework from a
theoretical and user perspective; a validation of a
simple set of evolutionary parameters is then provided
and three empirical software studies generated from
open-source software (OSS) are used to support claims
and generated results. The research illustrates how
simulation can be used to investigate a complex and
under-researched area of the development cycle. It also
shows the value of incorporating certain human traits

of the function. SRFPs find application in a wide
variety of physical settings.\par
We develop a family of retrospective-approximation (RA)
algorithms called Bounding RA that efficiently solves a
certain class of multidimensional SRFPs. During each
iteration, Bounding RA generates and solves a
sample-path problem by identifying a polytope of
stipulated diameter, with an image that bounds the
given target to within stipulated tolerance. Across
iterations, the stipulations become increasingly
stringent, resulting in a sequence of shrinking
polytopes that approach the correct
solution.\par
Efficiency results from: (i) the RA structure, (ii) the
idea of using bounding polytopes to exploit problem
structure, and (iii) careful step-size and direction
choice during algorithm evolution. Bounding RA has good
finite-time performance that is robust with respect to
the location of the initial solution, and algorithm
parameter values. Empirical tests suggest that Bounding
RA outperforms Simultaneous Perturbation Stochastic
Approximation (SPSA), which is arguably the best-known
algorithm for solving SRFPs.",

abstract = "This article gives several methods for approximating a
closed queueing network with a smaller one. The
objective is to reduce the simulation time of the
network. We consider Jackson-like networks with
Markovian routing and with general service
distributions. The basic idea is to first divide the
network into two parts --- the core nodes of interest
and the remaining nodes. We suppose that only metrics
at the core nodes are of interest. The remaining nodes
are collapsed into a reduced set of nodes, in an effort
to approximate the flows into and out of the set of
core nodes. The core nodes and their interactions are
preserved in the reduced network. We test the network
reductions for accuracy and speed. By randomly
generating sample networks, we test the reductions on a
large variety of test networks, rather than on a few
specific cases. The main conclusion is that the
reductions work well when the squared coefficients of
variation of the service distributions are not all
small (that is, the network is not close to being
deterministic) and for nodes where the utilization is
not too high or too low.",

approximated by truncated normal random variables. The
interarrival times are assumed to be identically and
independently distributed (i.i.d.), with a general
distribution of bounded density. We are interested in
calculating the sensitivities of the total cumulative
waiting time of all passengers with respect to the
interdeparture times. For this general model where
neither the interarrival times nor the interdeparture
times are exponential, there is no analytical formula
available. However, the estimation of such

$(t,s)$-sequences such as the Sobol' sequence are
usually preferred. To overcome this problem, one
possible approach is to include permutations in the

{\em generalized Halton sequences\/} --- an idea that
goes back to almost thirty years ago, and that has been
studied by many researchers in the last few years. In
parallel to these efforts, an important improvement in
the upper bounds for the discrepancy of Halton
sequences has been made by Atanassov in 2004. Together,
these two lines of research have revived the interest
in Halton sequences. In this article, we review
different generalized Halton sequences that have been
proposed recently, and compare them by means of

generalized Halton sequence which, we believe, offers a

Quality of Service (QoS) while maximizing network

Virtual Private Networks (VPN) and Peer-to-Peer (P2P)

Engineering (FISTE) approach proposed in this article
is a prediction-based approach that maps the ingress
traffic levels of a network to the QoS of end-to-end

simulation analysis and closed-form analysis, it can
treat a complex network as a black box. When we
combined Simulated Annealing (SA) with FISTE, the
resulting approach can provide a traffic engineering
solution so that multiple end-to-end QoS requirements
are satisfied while the network resource utilization is
maximized. FISTE originated from the concept of
Importance Sampling (IS), and our approach differs from
the previous Importance Sampling based approaches since

possess some nontrivial internal structure that varies
across and differentiates among distinct types of links
or nodes. In this work, we abstract such additional
information as network {\em annotations}. We introduce
a network topology modeling framework that treats
annotations as an extended correlation profile of a
network. Assuming we have this profile measured for a
given network, we present an algorithm to rescale it in
order to construct networks of varying size that still
reproduce the original measured annotation
profile.\par
Using this methodology, we accurately capture the
network properties essential for realistic simulations
of network applications and protocols, or any other
simulations involving complex network topologies,
including modeling and simulation of network evolution.
We apply our approach to the Autonomous System (AS)
topology of the Internet annotated with business
relationships between ASs. This topology captures the
large-scale structure of the Internet. In depth
understanding of this structure and tools to model it

implementation of a general framework for optimizing
the expected value of a performance measure of a
stochastic simulation with respect to integer-ordered
decision variables in a finite (but typically large)
feasible region defined by linear-integer constraints.
The framework consists of a global-search phase,
followed by a local-search phase, and ending with a
``clean-up'' (selection of the best) phase. Each phase
provides a probability 1 convergence guarantee as the
simulation effort increases without bound: Convergence
to a globally optimal solution in the global-search
phase; convergence to a locally optimal solution in the
local-search phase; and convergence to the best of a
small number of good solutions in the clean-up phase.
In practice, ISC stops short of such convergence by
applying an improvement-based transition rule from the
global phase to the local phase; a statistical test of
convergence from the local phase to the clean-up phase;
and a ranking-and-selection procedure to terminate the
clean-up phase. Small-sample validity of the
statistical test and ranking-and-selection procedure is
proven for normally distributed data. ISC is compared
to the commercial optimization via simulation package
OptQuest on five test problems that range from 2 to 20
decision variables and on the order of 10$^4$ to
10$^{20}$ feasible solutions. These test cases

article focuses on continuous optimization problems. In
the stochastic simulation setting where replications
are expensive but noise in the objective function
estimate could mislead the search process, the
allocation of simulation replications can make a
significant difference in the performance of such
global optimization search algorithms. A new allocation
scheme is developed based on the notion of optimal
computing budget allocation. The proposed approach
improves the updating of the sampling distribution by
carrying out this computing budget allocation in an
efficient manner, by minimizing the expected
mean-squared error of the CE weight function. Numerical
experiments indicate that the computational efficiency
of the CE method can be substantially improved if the
ideas of computing budget allocation are applied.",

abstract = "In simulation of complex stochastic systems, such as
Discrete-Event Systems (DES), statistical distributions
are used to model the underlying randomness in the
system. A sensitivity analysis of the simulation output
with respect to parameters of the input distributions,
such as the mean and the variance, is therefore of
great value. The focus of this article is to provide a
practical guide for robust sensitivity, respectively,
gradient estimation that can be easily implemented
along the simulation of a DES. We study the
Measure-Valued Differentiation (MVD) approach to
sensitivity estimation. Specifically, we will exploit
the ``modular'' structure of the MVD approach, by
firstly providing measure-valued derivatives for input
distributions that are of importance in practice, and
subsequently, by showing that if an input distribution
possesses a measure-valued derivative, then so does the
overall Markov kernel modeling the system transitions.
This simplifies the complexity of applying MVD
drastically: one only has to study the measure-valued
derivative of the input distribution, a measure-valued
derivative of the associated Markov kernel is then
given through a simple formula in canonical form. The
derivative representations of the underlying simple
distributions derived in this article can be stored in
a computer library. Combined with the generic MVD
estimator, this yields an automated gradient estimation
procedure. The challenge in automating MVD so that it
can be included into a simulation package is the
verification of the integrability condition to
guarantee that the estimators are unbiased. The key
contribution of the article is that we establish a
general condition for unbiasedness which is easily
checked in applications. Gradient estimators obtained
by MVD are typically phantom estimators and we discuss
the numerical efficiency of phantom estimators with the
example of waiting times in the G/G/1 queue.",

abstract = "The asymptotic robustness of estimators as a function
of a rarity parameter, in the context of rare-event
simulation, is often qualified by properties such as
bounded relative error (BRE) and logarithmic efficiency
(LE), also called asymptotic optimality. However, these
properties do not suffice to ensure that moments of
order higher than one are well estimated. For example,
they do not guarantee that the variance of the
empirical variance remains under control as a function
of the rarity parameter. We study generalizations of
the BRE and LE properties that take care of this
limitation. They are named bounded relative moment of
order $k$ (BRM-$k$) and logarithmic efficiency of order
$k$ (LE-$k$), where $ k \geq 1$ is an arbitrary real
number. We also introduce and examine a stronger notion
called vanishing relative centered moment of order $k$,
and exhibit examples where it holds. These properties
are of interest for various estimators, including the
empirical mean and the empirical variance. We develop
(sufficient) Lyapunov-type conditions for these
properties in a setting where state-dependent
importance sampling (IS) is used to estimate
first-passage time probabilities. We show how these
conditions can guide us in the design of good IS
schemes, that enjoy convenient asymptotic robustness
properties, in the context of random walks with
light-tailed and heavy-tailed increments. As another
illustration, we study the hierarchy between these
robustness properties (and a few others) for a model of
highly reliable Markovian system (HRMS) where the goal
is to estimate the failure probability of the system.
In this setting, for a popular class of IS schemes, we
show that BRM-$k$ and LE-$k$ are equivalent and that
these properties become strictly stronger when $k$
increases. We also obtain a necessary and sufficient
condition for BRM-$k$ in terms of quantities that can
be readily computed from the parameters of the model.",

we derive the asymptotic distributional properties of

well as their bias, variance, and mean squared error.
We also study linear combinations of these estimators,

importance in modeling interactions between

Traditionally, game-theoretic analysis relied on highly
stylized models to provide interesting insights about
problems at hand. The shortcoming of such models is
that they often do not capture vital detail. On the
other hand, many real strategic settings, such as
sponsored search auctions and supply-chains, can be
modeled in high resolution using simulations. Recently,
a number of approaches have been introduced to perform
analysis of game-theoretic scenarios via
simulation-based models. The first contribution of this
work is the asymptotic analysis of Nash equilibria
obtained from simulation-based models. The second
contribution is to derive expressions for probabilistic
bounds on the quality of Nash equilibrium solutions
obtained using simulation data. In this vein, we derive
very general distribution-free bounds, as well as
bounds which rely on the standard normality
assumptions, and extend the bounds to infinite games
via Lipschitz continuity. Finally, we introduce a new

developed and applied to modeling and runtime
optimization of throughput in a mobile ad hoc network,
a self-organizing collection of mobile wireless nodes

models generated in profile-driven regression are used
to fit an overall model of throughput, and are also
used to optimize controllable factors at runtime.
Unlike others, the throughput model accounts for node
speed. The resulting optimization is very effective;
locally optimizing the network factors at runtime
results in throughput as much as six times higher than
that achieved with the factors at their default
levels.",

required precision, which may be close to machine
precision for smooth, bounded densities; the necessary
tables have moderate size. Our computational
experiments with the classical standard distributions
(normal, beta, gamma, $t$-distributions) and with the
noncentral chi-square, hyperbolic, generalized
hyperbolic, and stable distributions showed that our
algorithm always reaches the required precision. The
setup time is moderate and the marginal execution time
is very fast and nearly the same for all distributions.
Thus for the case that large samples with fixed
parameters are required the proposed algorithm is the
fastest inversion method known. Speed-up factors up to
1000 are obtained when compared to inversion algorithms
developed for the specific distributions. This makes
our algorithm especially attractive for the simulation

the effect of CRN on metamodel parameter estimation and

response-surface prediction. In brief, we confirm that
CRN is detrimental to prediction, but show that it
leads to better estimation of slope parameters and

criterion for the construction of efficient samplers,
Lyapunov inequalities are useful for finding more
precise information, in the form of bounds, for the
behavior of the coefficient of variation of the
associated importance sampling estimator in the
prelimit. In addition, Lyapunov inequalities provide
insight into the various mollification procedures that
are often required in constructing associated

grid. The inverse of the cumulative distribution
function is obtained by linear interpolation. In this
article, we apply a Hilbert transform method for the
characteristic function inversion. The Hilbert
transform representation for the cdf can be discretized
using a simple rule highly accurately. Most
importantly, the error estimates admit explicit and
computable expressions, which allow us to compute the
cdf to any desired accuracy. We present an explicit
bound for the estimation bias in terms of the range of
the grid where probabilities are tabulated, the step
size of the grid, and the approximation error for the
probabilities. The bound can be computed from the
characteristic function directly and allows one to
determine the size and fineness of the grid and
numerical parameters for evaluating the Hilbert
transforms for any given bias tolerance level in
one-dimensional problems. For multidimensional
problems, we present a procedure for selecting the grid
and the numerical parameters that is shown to converge
theoretically and works well practically. The inverse
transform method is attractive not only for L{\'e}vy
processes that are otherwise not easy to simulate, but
also for processes with special structures that could
be simulated in different ways. The method is very fast
and accurate when combined with quasi-Monte Carlo
schemes and variance reduction techniques. The main
results we derived are not limited to L{\'e}vy
processes and can be applied to simulating from
tabulated cumulative distribution functions in general
and characteristic functions in our analytic class in
particular.",

in simulation due to its flexibility in global fitting
and prediction. In the fitting of this metamodel, the
parameters are often estimated from the simulation
data, which introduces parameter estimation
uncertainties into the overall prediction error.
Traditional plug-in estimators usually ignore these
uncertainties, which can be substantial in stochastic
simulations. This typically leads to an underestimation
of the total variability and an overconfidence in the
results. In this article, a Bayesian metamodeling
approach for kriging prediction is proposed for
stochastic simulations to more appropriately account
for the parameter uncertainties. We derive the
predictive distribution under certain assumptions and
also provide a general Markov Chain Monte Carlo
analysis approach to handle more general assumptions on
the parameters and design. Numerical results indicate
that the Bayesian approach has better coverage and
better predictive variance than a previously proposed
modified nugget effect kriging model, especially in
cases where the stochastic variability is high. In
addition, we further consider the important problem of
planning the experimental design. We propose a
two-stage design approach that systematically balances

represents the processes associated with a system of

running in their own CSPs on different computers linked
together over a communications network via distributed
simulation software. The creation of a distributed
simulation with CSPs is still complex and typically
requires a partnership of problem owners, modelers, CSP
vendors, and distributed simulation specialists. In an
attempt to simplify this development and foster
discussion between modelers and technologists, the
SISO-STD-006-2010 Standard for COTS Simulation Package
Interoperability Reference Models has been developed.
The standard makes it possible to capture
interoperability capabilities and requirements at a DES
modeling level rather than a computing technical level.
For example, it allows requirements for entity transfer
between models to be clearly specified in DES terms
(e.g. the relationship between departure and arrival
simulation times and input element (queue, workstation,
etc.)), buffering rules, and entity priority, instead of
using specialist technical terminology. This article

over intervening points, thereby resulting in fast

that HLA supports both conservative and optimistic

some peculiarities of the optimistic approach, force
most simulators to use the conservative approach. In

a mapping allows transparent optimistic execution (and

is achieved without the need to modify the RTI services

depends on many design parameters and thus, requires a
significant effort to tune these parameters. In this
article, we introduce an Adaptive Equi-Energy (AEE)
sampler that automates the choice of the selection
mechanism when jumping onto a state of the
higher-temperature chain. We prove the ergodicity and a
strong law of large numbers for AEE, and for the
original Equi-Energy sampler as well. Finally, we apply

statistical data-structure that is sufficient for
nonparametric density estimation of massive,
multidimensional metric data. This data-structure is
formalized as statistical regular paving (SRP). A

selectively bisecting boxes along their first widest
side. SRP augments RP by mutably caching the
recursively computable sufficient statistics of the
data. The base Markov chain used to propose moves for
the Metropolis--Hastings chain is a random walk that
data-adaptively prunes and grows the SRP histogram
tree. We use a prior distribution based on Catalan
numbers and detect convergence heuristically. The
performance of our posterior mean SRP histogram is
empirically assessed for large sample sizes simulated

abstract = "Consider a system of $N$ identical hard spherical
particles moving in a $d$-dimensional box and
undergoing elastic, possibly multiparticle, collisions.
We develop a new algorithm that recovers the
precollision state from the post-collision state of the
system, across a series of consecutive collisions, with
essentially no memory overhead. The challenge in
achieving reversibility for an $n$-particle collision
(where, in general, $ n \ll N$) arises from the
presence of $ n d - d - 1$ degrees of freedom
(arbitrary angles) during each collision, as well as
from the complex geometrical constraints placed on the
colliding particles. To reverse the collisions in a
traditional simulation setting, all of the particular
realizations of these degrees of freedom (angles)
during the forward simulation must be tracked. This
requires memory proportional to the number of
collisions, which grows very fast with $N$ and $d$,
thereby severely limiting the de facto applicability of
the scheme. This limitation is addressed here by first
performing a pseudorandomization of angles, which
ensures determinism in the reverse path for any values
of $n$ and $d$. To address the more difficult problem
of geometrical and dynamic constraints, a new approach
is developed which correctly samples the constrained
phase space. Upon combining the pseudorandomization
with correct phase space sampling, perfect
reversibility of collisions is achieved, as illustrated
for $ n \leq 3$, $ d = 2$, and $ n = 2$, $ d = 3$. This
result enables, for the first time, reversible
simulations of elastic collisions with essentially zero
memory accumulation. In principle, the approach
presented here could be generalized to larger values of
$n$. The reverse computation methodology presented here
uncovers important issues of irreversibility in
conventional models, and the difficulties encountered
in arriving at a reversible model for one of the most
basic and widely used physical system processes,
namely, elastic collisions for hard spheres. Insights
and solution methodologies, with regard to accurate
phase space coverage with reversible random sampling
proposed in this context, can help serve as models and
/ or starting points for other reversible
simulations.",

systems. Researchers have studied a number of aspects
of the system, including its scalability, performance,
efficiency and fairness. However, the complexity of the
system has forced most prior analytical work to make a
number of simplifying assumptions, for example, user
homogeneity, or even ignore some central aspects of the
protocol altogether, for example, the rate-based
Tit-for-Tat (TFT) unchoking scheme, in order to keep
the analysis tractable. Motivated by this, in this
article we propose two analytical models that
accurately predict the performance of the system while
considering the central details of the BitTorrent
protocol. Our first model is a steady-state one, in the
sense that it is valid during periods of time where the
number of users remains fixed. Freed by the
complications of user time-dynamics, we account for
many of the central details of the BitTorrent protocol
and accurately predict a number of performance metrics.
Our second model combines prior work on fluid models
with our first model to capture the transient behavior
as new users join or old users leave, while modelling
many major aspects of BitTorrent. To the best of our
knowledge, this is the first model that attempts to
capture the transient behavior of many classes of
heterogeneous users. Finally, we use our analytical
methodology to introduce and study the performance of a
flexible token-based scheme for BitTorrent, show how
this scheme can be used to block freeriders and
tradeoff between higher-bandwidth and lower-bandwidth
users performance, and evaluate the scheme's parameters
that achieve a target operational point.",

aggregated network traffic, we focus on studying
isolated traffic flows. Per-application flow
characterization caters to the need of network control
functions such as traffic scheduling and admission
control at the edges of the network. Such control
functions necessitate differentiating network traffic
on a per-application basis. The ``entropy
fingerprints'' that we get from our entropy estimator
summarize many characteristics of each application's
network traffic. Not only can we compare applications
on the basis of peak entropy, but we can also
categorize them based on a number of other properties

The design is used to define alternative execution

on expending $c$ units of computer time to estimate a
quantity $ \alpha $. In comparing competing estimators
for $ \alpha $, a natural figure of merit is to choose
the estimator that minimizes the computation time
needed to reduce the error probability {$ P(| \alpha
(c) - \alpha | > \epsilon) $} to below some prescribed
value $ \delta $ . In this paper, we develop large
deviations results that provide approximations to the
computational budget necessary to reduce the error
probability to below $ \delta $ when $ \delta $ is
small. This approximation depends critically on both
the distribution of the estimator itself and that of
the random amount of computer time required to generate
the estimator, and leads to different conclusions
regarding the choice of preferred estimator than those
obtained when one requires the error tolerance $
\epsilon $ to be small. The ``small $ \epsilon $ ''
regime leads to variance-based selection criteria, and
has a long history in the simulation literature going
back to Hammersley and Handscomb.",

abstract = "Researchers in the area of grid/cloud computing
perform many of their experiments using simulations
that must capture network behavior. In this context,
packet-level simulations, which are widely used to
study network protocols, are too costly given the
typical large scales of simulated systems and
applications. An alternative is to implement network
simulations with less costly flow-level models. Several
flow-level models have been proposed and implemented in
grid/cloud simulators. Surprisingly, published
validations of these models, if any, consist of
verifications for only a few simple cases.
Consequently, even when they have been used to obtain
published results, the ability of these simulators to
produce scientifically meaningful results is in doubt.
This work evaluates these state-of-the-art flow-level
network models of TCP communication via comparison to
packet-level simulation. While it is straightforward to
show cases in which previously proposed models lead to
good results, instead we follow the critical method,
which places model refutation at the center of the
scientific activity, and we systematically seek cases
that lead to invalid results. Careful analysis of these
cases reveals fundamental flaws and also suggests
improvements. One contribution of this work is that
these improvements lead to a new model that, while far
from being perfect, improves upon all previously
proposed models in the context of simulation of grids
or clouds. A more important contribution, perhaps, is
provided by the pitfalls and unexpected behaviors
encountered in this work, leading to a number of
enlightening lessons. In particular, this work shows
that model validation cannot be achieved solely by
exhibiting (possibly many) ``good cases.'' Confidence
in the quality of a model can only be strengthened
through an invalidation approach that attempts to prove
the model wrong.",

abstract = "Analysts using simulation models often must assess a
large number of alternatives in order to determine
which are most effective. If effectiveness corresponds
to the likelihood of yielding the best outcome, this
becomes a multinomial selection problem. Unfortunately,
existing procedures were developed primarily for
evaluating small sets of alternatives, so parameters
required to implement them may not be readily available
or the sampling costs may be prohibitive when a large
number of alternatives are present. We propose a
truncated, sequential multinomial subset selection
procedure that restricts the maximum subset size.
Numerical comparisons show that our procedure can be
much more efficient than the leading unrestricted
procedure. Our procedure requires only one calculated
parameter rather than four. We provide extensive tables
for cases involving large numbers of alternatives.",

variety of applications, including econometrics and

scenario where the likelihood function cannot be
evaluated pointwise; in such cases, one cannot perform
exact statistical inference, including parameter
estimation, which often requires advanced computational
algorithms, such as Markov Chain Monte Carlo (MCMC). We
introduce a new approximation based upon Approximate
Bayesian Computation (ABC). Under some conditions, we
show that as $ n \to \infty $, with $n$ the length of
the time series, the ABC posterior has, almost surely,
a Maximum A Posteriori (MAP) estimator of the
parameters that is often different from the true
parameter. However, a noisy ABC MAP, which perturbs the
original data, asymptotically converges to the true
parameter, almost surely. In order to draw statistical
inference, for the ABC approximation adopted, standard
MCMC algorithms can have acceptance probabilities that
fall at an exponential rate in n and slightly more
advanced algorithms can mix poorly. We develop a new
and improved MCMC kernel, which is based upon an exact
approximation of a marginal algorithm, whose cost per
iteration is random, but the expected cost, for good
performance, is shown to be $ O(n^2)$ per iteration. We
implement our new MCMC kernel for parameter inference

studies a new class of kernels based on the

in statistical physics over the last decade. Though the
importance of this family of distributions is
attributed to its ability to generalize the Gaussian

almost all existing smoothing kernels. This motivates
us to study SF schemes for gradient estimation using
the $q$ -Gaussian distribution. Using the derived
gradient estimates, we propose two-timescale algorithms
for optimization of a stochastic objective function in

Estimators) that approximates the optimal simulation

Gaussian. We first characterize the nature of the
optimal simulation budget as a bi-level optimization
problem. We then show that under a certain asymptotic
limit, the solution to the bi-level optimization
problem becomes surprisingly tractable and is expressed
through a single intuitive measure, the score. We
provide an iterative SO algorithm that repeatedly
estimates the score and determines how the available
simulation budget should be expended across contending
systems. Numerical experience with the algorithm
resulting from the proposed sampling approximation is
very encouraging --- in numerous examples of
constrained SO problems having 1,000 to 10,000 systems,

of a computer simulation model of a system or process
often depends on many factors; many times, however,
only a few of these factors are important. Sequential
bifurcation is a method that has been considered by
several authors for identifying these important factors
using as few runs of the simulation model as possible.
In this article, we propose a new sequential
bifurcation procedure whose steps use a key stopping
rule that can be calculated explicitly, something not
available in the best methods previously considered.
Moreover, we show how this stopping rule can also be
easily modified to efficiently identify those factors
that are important in influencing the variability
rather than the mean of the output. In empirical
studies, the new method performs better than previously
published fully sequential bifurcation methods in terms
of achieving the prescribed Type I error. It also
achieves higher power for detecting moderately large
effects using fewer replications than earlier methods.
To achieve this control for midrange effects, the new
method sometimes requires more replications than other
methods in the case where there are many very large
effects.",

clustering techniques to describe the behavior of end
hosts as a function of multidimensional attributes and
group them into distinct classes, and then map the
classes to simulated routers so that we can generate
traffic in accordance with the cluster-level
statistics. The proposed traffic generator makes no
assumption on the target network topology. It is also
capable of scaling the generated traffic so that the
traffic intensity can be varied accordingly in order to
test applications under different and yet realistic

This article proposes a novel methodology to integrate

Constraint programming naturally allows the modeling of
dependencies among components of the problem as
constraints, facilitating the integration and use of
different forms of knowledge. The new paradigm,
referred to as constrained community network, uses
constraints to capture properties of the regulatory
networks (e.g., topological properties) and to guide
the integration of knowledge derived from different

Parameterized choices for the algorithmic method and

replacing them by the passage of time. We use TADSim to
quickly characterize the runtime performance and
algorithmic behavior for the otherwise long-running

extensions, such as speculative spawning of the
compute-bound stages, and predict performance
improvements without having to implement such a method.
Validation against the actual TAD code shows close

Interference is typically managed using operating
system scheduling support (e.g., gang scheduling), a
heavyweight approach with some drawbacks. We propose an
application-level approach to interference resilience
through alternative simulation scheduling and mapping
algorithms. More precisely, the most resilient
simulators allow dynamic mapping of simulation event
execution to processing resources (a work pool model).
However, this model has significant scheduling overhead
and poor cache locality. Thus, we investigate using
application-level interference mitigation where the
application detects the presence of interference and
reacts by changing the thread task allocation.
Specifically, we propose a locality-aware adaptive
dynamic mapping (LADM) algorithm that adjusts the
number of active threads on the fly by detecting the
presence of interference. LADM avoids having the
application stall when threads are inactive due to
context switching. We investigate different mechanisms

simulation as a method of reusing data to generate
variance estimators with asymptotically lower variance.
In this article, we apply the OBM method to stochastic
programming by formulating a variant of the multiple
replications procedure used for assessing solution
quality. We give conditions under which the resulting
optimality gap point estimators are strongly
consistent, the optimality gap interval estimators are
asymptotically valid, and the OBM variance estimators
for optimality gap have asymptotically lower variances
relative to their nonoverlapping counterparts [Meketon
and Schmeiser 1984; Welch 1987]. We investigate
computational efficiency, a combined measure of
variance and computation time, providing guidelines on
the degree of overlap. Numerical experiments on several
test problems are presented, examining the small-sample
behavior and the empirical computational efficiency of
the overlapping batches method in this context.",

applications in communication, computer, and
fabrication networks. Steady-state performance measures
associated with these networks is often a topic of
interset. Conceptually, under mild conditions, a
sequence of regeneration times exists in multiclass
networks, making them amenable to regenerative
simulation for estimating steady-state performance
measures. However, typically, identification of such a
sequence in these networks is difficult. A well-known
exception is when all interarrival times are
exponentially distributed, where the instants
corresponding to customer arrivals to an empty network
constitute a sequence of regeneration times. In this
article, we consider networks in which the interarrival
times are generally distributed but have exponential or
heavier tails. We show that these distributions can be
decomposed into a mixture of sums of independent random
variables such that at least one of the components is
exponentially distributed. This allows an easily
implementable embedded sequence of regeneration times
in the underlying Markov process. We show that among
all such interarrival time decompositions, the one with
an exponential component that has the largest mean
minimizes the asymptotic variance of the standard
deviation estimator. We also show that under mild
conditions on the network primitives, the regenerative
mean and standard deviation estimators are consistent
and satisfy a joint central limit theorem useful for
constructing asymptotically valid confidence
intervals.",

be more consistently and substantially increased by a
different transformation. We first transform the given
sequence to a sequence of mean-1 exponential random
variables, which is equivalent to a rate-1 Poisson
process. We then apply the classical
conditional-uniform transformation to convert the
arrival times into i.i.d. random variables uniformly
distributed on $[0, 1]$. And then, after those two
preliminary steps, we apply the original Durbin
transformation. Since these KS tests assume a fully

to avoid wasting time and resources on overoptimistic

most obvious choice. Moreover, the unique runtime
dynamics and configuration choices of Cloud and VM
platforms introduce new design considerations and
runtime characteristics specific to PDES over
Cloud/VMs. Here, an empirical study is presented to
help understand the dynamics, trends, and trade-offs in

uncovered is the fundamental mismatch in hypervisor
scheduler policies designed for general Cloud workloads
versus the virtual time ordering needed for PDES
workloads. This insight is supported by experimental
data revealing the gross deterioration in PDES
performance traceable to VM scheduling policy. To
overcome this fundamental problem, the design and

computationally infeasible. This article introduces a
grammar-based approach to formalize and identify the
existence and extent of emergence without the need for
prior knowledge of emergent properties. Our approach is
based on weak (basic) emergence that is both generated
and autonomous from the underlying agents. We employ
formal grammars to capture agent interactions in the
forms of words written on a common tape. Our formalism
captures agents of diverse types and open systems. We
propose an automated approach for the identification of
emergent behavior and show its benefits through
theoretical and experimental analysis. We also propose
a significant reduction of state-space explosion
through the use of our proposed degree of interaction
metrics. Our experiments using the boids model show the
feasibility of our approach but also highlight future
avenues of improvement.",

(connections) describe and constrain the communication,

Defining couplings between a large set of components in
an extensional manner-listing all existing couplings
individually-often proves to be rather tedious.
Moreover, if models change their structure, that is,
composition and interaction patterns and, in some
cases, even their interfaces during simulation,
questions about the consistency of the couplings arise.
For instance, an extensionally defined coupling may
refer to a model that no longer exists. Instead, an
intensional coupling definition, based on attributes of
the components to couple and dynamically translated
into concrete couplings during simulation, promises to
alleviate these problems. We propose a concept that
combines a flexible, yet expressive, definition of
couplings that rests on component interfaces announcing
attributes of interest. However, intensional couplings
come at a price, as they need to be translated during
simulation; in variable-structure models, this
translation has to happen frequently. We illuminate our
concept based on a revision of the modeling formalism
Multilevel Discrete Event System Specification (
ML-DEVS). Developed for multilevel modeling and
simulation, ML-DEVS exhibits another alternative to
intensional couplings, that is, sharing parts of model
states for up- and downward causation. The intricate

analyze the resulting estimator as the total

results. Then we show that improved convergence rates
can be obtained through the use of techniques other

indicate that the use of quasi-random sequences yields
a better convergence rate than independent sampling,

article, an enhanced Null-message algorithm called FNM
is presented that uses domain-specific knowledge to
improve the performance of the basic Null-message

The forecast information is carried in the enhanced

dynamic system lookahead that is much greater than what
the static system structure provides. This improved
lookahead allows better exploitation of the simulation
model's inherent parallelism and leads to better
performance. Compared with the basic Null-message
algorithm, FNM greatly reduces the amount of
Null-messages and improves parallel simulation
performance as a result, while at the same time it
guarantees simulation correctness as the basic

Hence, a natural question to consider is whether this
independence assumption can be relaxed while still
attaining an elegant and tractable model that permits
an efficient Monte Carlo algorithm for unreliability
estimation. In this article, we provide one possible
answer by considering a static network reliability
model with dependent link failures, based on a
Marshall-Olkin copula, which models the dependence via
shocks that take down subsets of components at
exponential times, and propose a collection of adapted
versions of permutation Monte Carlo (PMC, a conditional
Monte Carlo method), its refinement called the turnip
method, and generalized splitting (GS) methods to
estimate very small unreliabilities accurately under
this model. The PMC and turnip estimators have bounded
relative error when the network topology is fixed while
the link failure probabilities converge to 0, whereas
GS does not have this property. But when the size of
the network (or the number of shocks) increases, PMC
and turnip eventually fail, whereas GS works nicely
(empirically) for very large networks, with over 5,000
shocks in our examples.",

called single barrier (SBA) approach, was initially

Evolutionary Greedy Strategy (EGS), was implemented by
introducing multibarrier protection measures in order
to improve the efficiency of the final solution.
Finally, a Coevolutionary Cooperative Strategy (CCS),
has been introduced where all barriers are encoded in
the genotype and, because all the constituents parts of

differentiation waves and associated signaling
pathways. In the current work, we focus on the
Notch/Delta signaling pathway, which is not only known
to trigger such waves but also is used to achieve the
principle of lateral inhibition (i.e., a competition

signaling pathways, and extrinsic stochastic
fluctuations attributed to microenvironmental factors.
However, the effect of intrinsic and extrinsic noise on
cell fate determination is an open problem. Our goal is
to elucidate how the induction of extrinsic noise
affects cell fate specification in a lateral inhibition

abstract = "Serious problems with bridging multiple scales in the
scope of a single numerical model make computer
simulations too demanding computationally and highly
unreliable. We present a new concept of modeling
framework that integrates the particle method with
graph dynamical systems, called the particle automata
model (PAM). We assume that the mechanical response of
a macroscopic system on internal or external stimuli
can be simulated by the spatiotemporal dynamics of a
graph of interacting particles representing
fine-grained components of biological tissue, such as
cells, cell clusters, or microtissue fragments.
Meanwhile, the dynamics of microscopic processes can be
represented by evolution of internal particle states
represented by vectors of finite-state automata. To
demonstrate the broad scope of application of PAM, we
present three models of very different biological
phenomena: blood clotting, tumor proliferation, and
fungal wheat infection. We conclude that the generic
and flexible modeling framework provided by PAM may
contribute to more intuitive and faster development of
computational models of complex multiscale biological
processes.",

shared memory technologies to alleviate the high
latency experienced by off-chip memory transfers, but
the high architectural complexity of modern multicore
processors has presented many questions. To tackle the
design of efficient algorithms scheduling workloads
over available cores, this article presents a parallel
bioinspired model that simulates the utilization of
shared memory on multicore systems. The proposed model
is based on cellular automata (CA) and coupled with
game theory principles. CA are selected due to their
inherent parallelism and especially their ability to
incorporate inhomogeneities. Furthermore, the novelty
of the model is realized on the fact that multilevel CA
are used to simulate the different levels of cache
memory usually found in multicore processors. These
characteristics make the model able to cope with the
increasing diversity of cache memory hierarchies on
modern and future processors. Nonetheless, by acquiring
data from hardware performance counters and processing
them with the proposed model online, the performance of
the system can be calculated and a better scheduling
strategy can be adopted in real time. The CA-based
model was verified on the behavior of a real multicore
system running a multithreaded application, and it
successfully simulated the acceleration achieved by an
increased number of cores available for the execution
of the workload. More specifically, the example of
common pool resource from game theory was used with two
variations: a static and a variable initial endowment.
The static variation of the model approximates slightly
better the acceleration of a workload when the number
of available processor cores increases, whereas the
dynamic variation simulates better the moderate
differences due to operation system's scheduler
alternations on the same amount of cores.",

renewable generators in electrical power grids,
connection overloads are of increasing concern for grid
operators. The risk of an overload due to injection
variability can be described mathematically as a
barrier-crossing probability of a function of a
multidimensional stochastic process. Crude Monte Carlo
is a well-known technique to estimate probabilities,
but it may be computationally too intensive in this
case as typical modern power grids rarely exhibit
connection overloads. In this article, we derive an
approximate rate function for the overload probability
using results from large deviations theory. Based on
this large deviations approximation, we apply a rare
event simulation technique called splitting to estimate
overload probabilities more efficiently than Crude
Monte Carlo simulation. We show on example power grids
with up to 11 stochastic power injections that for a
fixed accuracy, Crude Monte Carlo would require tens to
millions as many samples as the proposed splitting
technique required. We investigate the balance between
accuracy and workload of three splitting schemes, each
based on a different approximation of the rate
function. We justify the workload increase of
large-deviation-based splitting compared to naive
splitting-that is, splitting based on merely the
Euclidean distance to the rare event set. For a fixed
accuracy, naive splitting requires over 60 times as
much CPU time as large-deviation-based splitting,

Event System Specification) formalism enables
hierarchical modeling, so it provides an efficiency in
the model development of complex models. However, the
hierarchical modeling incurs prolonged simulation
executions due to indirect event exchanges through the
model hierarchy. Although direct event paths are
applied to mitigate this overhead, the situation
becomes even worse when a model changes its structures
during simulation execution, called a dynamic structure
model. This article suggests Coupling Relation Graph
(CRG) and Strongly Coupled Component (SCC) concepts to
improve hierarchical and dynamic structure DEVS

representing DEVS model structure, and SCC is a group
of connected components in a CRG. Using CRG and SCC,
this article presents (1) how to develop CRG from a
DEVS model and (2) how to construct and update direct
event paths with respect to dynamic structural changes.
In particular, compared to the previous works, the
proposed method focuses on the reduction of the
updating costs for the direct event paths. Through
theoretical and empirical analyses, this article shows
that the proposed method significantly reduces the

model contains lots of components and changes its model

stochastic systems, the simulation is often driven by
input models estimated from finite real-world data. A
complete statistical characterization of system
performance estimates requires quantifying both input
model and simulation estimation errors. The components
of input models in many complex systems could be
dependent. In this paper, we represent the distribution
of a random vector by its marginal distributions and a
dependence measure: either product-moment or Spearman
rank correlations. To quantify the impact from
dependent input model and simulation estimation errors
on system performance estimates, we propose a
metamodel-assisted bootstrap framework that is
applicable to cases when the parametric family of
multivariate input distributions is known or unknown.
In either case, we first characterize the input models
by their moments that are estimated using real-world
data. Then, we employ the bootstrap to quantify the
input estimation error, and an equation-based
stochastic kriging metamodel to propagate the input
uncertainty to the output mean, which can also reduce

model that is able to study emergent behaviors in a
population of agents who compete, through adaptation,
for scarce resources. The original formulation of the
game was inspired by the W.B. Arthur's El Farol Bar
problem: a fixed number of people have to independently
decide, each week, whether to go to a bar having a
limited capacity. People's choices are only affected by
the information about the number of visitors who
attended the bar in the past weeks. Basic MG assumes
that the information about the past game outcomes is
publicly available, and it does not contemplate any
communication among players. This article proposes the
Dynamic Sociality Minority Game (DSMG). DSMG is an
original variant of the classic MG where (1)
information about the outcome of the previously played
game step is only known to agents that really attended
the bar the previous week, and (2) a dynamically
established acquaintance network is introduced to
propagate such information to nonattendant players.
Specific settings of the game are identified in which
DSMG is able to show a better coordination level among
players with respect to the standard MG. Emergent
properties of the DSMG along with players' wellness are
thoroughly analyzed through agent-based simulation of a
simple road-traffic model.",

molecules is small. Hence a stochastic
reaction-diffusion simulator capable of working at
scale can provide a more accurate view of molecular
dynamics within the cell. This article describes a
parallel discrete event simulator, Neuron Time
Warp-Multi Thread (NTW-MT), developed for the
simulation of reaction diffusion models of neurons. To
the best of our knowledge, this is the first parallel
discrete event simulator oriented toward stochastic
simulation of chemical reactions in a neuron. The
simulator was developed as part of the NEURON project.
NTW-MT is optimistic and thread based, which attempts
to capitalize on multicore architectures used in high
performance machines. It makes use of a multilevel
queue for the pending event set and a single rollback
message in place of individual antimessages to disperse
contention and decrease the overhead of processing
rollbacks. Global Virtual Time is computed
asynchronously both within and among processes to get
rid of the overhead for synchronizing threads. Memory
usage is managed in order to avoid locking and
unlocking when allocating and deallocating memory and
to maximize cache locality. We verified our simulator
on a calcium buffer model. We examined its performance
on a calcium wave model, comparing it to the
performance of a process based optimistic simulator and
a threaded simulator which uses a single priority queue
for each thread. Our multithreaded simulator is shown
to achieve superior performance to these simulators.
Finally, we demonstrated the scalability of our
simulator on a larger Calcium-Induced Calcium Release
(CICR) model and a more detailed CICR model.",

performance of Parallel Discrete Event Simulation
platforms relying on the Time Warp (optimistic)
synchronization protocol. Among them we can mention
optimized approaches for state restore, as well as
techniques for load balancing or (dynamically)
controlling the speculation degree, the latter being
specifically targeted at reducing the incidence of
causality errors leading to waste of computation.
However, in state-of-the-art Time Warp systems, events'
processing is not preemptable, which may prevent the
possibility to promptly react to the injection of
higher priority (say, lower timestamp) events. Delaying
the processing of these events may, in turn, give rise
to higher incidence of incorrect speculation. In this
article, we present the design and realization of a
fine-grain time-sharing Time Warp system, to be run on
multi-core Linux machines, which makes systematic use
of event preemption in order to dynamically reassign
the CPU to higher priority events/tasks. Our proposal
is based on a truly dual mode execution, application
versus platform, which includes a timer-interrupt-based
support for bringing control back to platform mode for
possible CPU reassignment according to very fine grain
periods. The latter facility is offered by an ad-hoc
timer-interrupt management module for Linux, which we
release, together with the overall time-sharing
support, within the open source ROOT-Sim platform. An
experimental assessment based on the classical PHOLD
benchmark and two real-world models is presented, which
shows how our proposal effectively leads to the
reduction of the incidence of causality errors,

Discrete Event Simulation (PDES) is universally
considered a viable solution to exploit the intrinsic

execution speedup. Yet it leads the PDES system to
execute events in an order that may generate causal
inconsistencies that need to be recovered via rollback,
which requires restoration of a previous (consistent)
simulation state whenever a causality violation is
detected. The rollback operation is so critical for the
performance of a Time Warp system that it has been
extensively studied in the literature for decades to
find approaches suitable to optimize it. The proposed
solutions can be roughly classified as based on either
checkpointing or reverse computing. In this article, we
explore the practical design and implementation of a
fully new approach based on the runtime generation of
so-called undo code blocks, which are blocks of
instructions implementing the reverse memory side
effects generated by the forward execution of the
events. However, this is not done by recomputing the
original values to be restored, as instead it occurs in
reverse computing schemes. Hence, the philosophy undo
code blocks rely on is similar in spirit to that of
undo-logs (as a form of checkpointing). Nevertheless,
they are not data logs (as instead checkpoints are);
rather, they are logs of instructions. Our proposal is
fully transparent, thanks to the reliance on static
software instrumentation (targeting the x86
architecture and Linux systems). Also, as we show, it
can be combined with classical checkpointing to further
improve the runtime behavior of the state
recoverability support as a function of the workload.
We also present experimental results related to our
implementation, which is released as free software and
fully integrated into the open source ROOT-Sim package.

generic model encompasses all functionality needed by
optimistic simulation using reverse computation. We
then describe a parser system that uses a standardized
gate library to create a specific model for simulation.
The generated model is composed of several functions,
including those needed for an accurate model of timing
behavior. To quantify the improvements that an
automatically generated model can have over a hand
written model, we compare two gate library models: an
automatically generated lsi-10k library model and a
previously investigated, handwritten, simplified gtech
library model. We conclude that the automatically
generated model is a more accurate model of actual
hardware. In comparison to previous results, we find
that the automatically generated model is able to
achieve better optimistic simulation performance when
measured against conservative simulation. To test the
automatically generated model, we evaluate the
performance of a simulation of a full-scale OpenSPARC
T2 processor model. This model consists of nearly 6

Parallelization of agent-based traffic simulations is

by a Logical Process (LP). There are data dependencies
between LPs which require synchronization of LPs. An
asynchronous protocol allows LPs to progress and

lookahead means less frequent synchronization
operations. High synchronization overhead is still a
major performance issue of large-scale parallel

methods to increase the lookahead of LPs for an

advantage of uncertainties in traffic simulation to

The bottom-up cloning strategy is an improved strategy

increased the amount of communication traffic. Hence,
it is necessary both in academia and industry to
research load distribution methods for mobile networks.
An evaluation environment for large-scale networks that
behaves like a practical system is necessary to
evaluate these methods, and either a physical
environment or simulation environment can be used.
However, physical and simulation environments each have
their advantages and disadvantages. A physical
environment is suitable for practical operation because
it is possible to obtain data from a real environment.
In contrast, the cost for a large number of nodes and
the difficulty of field preparation are its
disadvantages. Reproducing radio propagation is also a
challenge. Network simulators solve the disadvantages
of the physical environment by modeling the entire
evaluation environment. However, they do not exactly
reproduce the physical environment because the nodes
are abstracted. This article presents an evaluation
environment that combines a network simulator and
virtual machines with virtual wireless Local Area
Network (LAN) devices. The virtual machines reproduce
the physical environment with high fidelity by running
the programs of the physical machines, and the virtual
wireless LAN devices make it possible to emulate
wireless LAN communication using default operating
system drivers. A network simulator and virtual

burden of field preparation, and reproduce radio
propagation by modeling the evaluation environment. In
the evaluation, the proposed method decreased the

parallel architecture simulator called ParTejas.
ParTejas is a timing simulation engine that gets its
execution traces from instrumented binaries using a
fast shared-memory-based mechanism. Subsequently, the
waiting threads simulate the execution of multiple
pipelines and an elaborate memory system with support
for multilevel coherent caches. ParTejas is written in
Java and primarily derives its speedups from the use of
novel data structures. Specifically, it uses lock-free
slot schedulers to design an entity called a parallel
port that effectively models the contention at shared
resources in the CPU and memory system. Parallel ports
remove the need for fine-grained synchronization and
allow each thread to use its local clock. Unlike
conventional simulators that use barriers for
synchronization at epoch boundaries, we use a
sophisticated type of barrier, known as a phaser. A
phaser allows threads to perform additional work
without waiting for other threads to arrive at the
barrier. Additionally, we use a host of Java-specific
optimizations and use profiling to effectively schedule
the threads. With all our optimizations, we demonstrate
a speedup of 11.8$ \times $ for a multi-issue in-order
pipeline and 10.9$ \times $ for an out-of-order
pipeline with 64 threads, for a suite of seven Splash2
and Parsec benchmarks. The simulation error is limited
to 2\% to 4\% as compared to strictly sequential

assess the performance of a stochastic system, there
exist two sources of uncertainty in the performance

In this article, we develop a budget allocation
approach that can efficiently employ the potentially
tight simulation resource to construct a percentile
confidence interval quantifying the impact of the input
uncertainty on the system performance estimates, while
controlling the simulation estimation error.
Specifically, nonparametric bootstrap is used to
generate samples of input models quantifying both the
input distribution family and parameter value
uncertainty. Then, the direct simulation is used to
propagate the input uncertainty to the output response.
Since each simulation run could be computationally
expensive, given a tight simulation budget, we propose
an efficient budget allocation approach that can
balance the finite sampling error introduced by using
finite bootstrapped samples to quantify the input
uncertainty and the system response estimation error
introduced by using finite replications to estimate the
system response at each bootstrapped sample. Our
approach is theoretically supported, and empirical

to be effective tools in modelling a wide range of
dynamic systems, providing a high-level description

However, their application is sometimes hampered
because the quantitative details of many real-world

in machine learning, there has been work to develop
probabilistic programming languages, which provide
system descriptions that incorporate uncertainty and
leverage advanced statistical techniques to infer
unknown parameters from observed data. Unfortunately,
current probabilistic programming languages are
typically too low-level to be suitable for complex

instance of the probabilistic programming paradigm
being applied to a high-level, formal language, and its
supporting tool suite. We explain the semantics of the
language in terms of a quantitative generalisation of
Constraint Markov Chains and describe the
implementation of the language, discussing in some
detail the different inference algorithms available and
their domain of applicability. We conclude by
illustrating the use of the language on simple but

behave stochastically, for example, when inputs,
message delays, or failures conform to a probability
distribution. However, reasoning analytically about the
behavior of complex stochastic systems is generally
infeasible. While simulations of systems are commonly
used in engineering practice, they have not
traditionally been used to reason about formal
specifications. Statistical model checking (SMC)
addresses this weakness by using a simulation-based
approach to reason about precise properties specified
in a stochastic temporal logic. A specification for a
communication system may state that within some time
bound, the probability that the number of messages in a
queue will be greater than 5 must be less than 0.01.
Using SMC, executions of a stochastic system are first
sampled, after which statistical techniques are applied
to determine whether such a property holds. While the
output of sample-based methods are not always correct,
statistical inference can quantify the confidence in
the result produced. In effect, SMC provides a more
widely applicable and scalable alternative to analysis
of properties of stochastic systems using numerical and
symbolic methods. SMC techniques have been successfully
applied to analyze systems with large state spaces in
areas such as computer networking, security, and
systems biology. In this article, we survey SMC
algorithms, techniques, and tools, while emphasizing

is a special case of the multi-objective simulation

estimators, the decision space or number of systems is
finite, and each system can be sampled to some extent.
The solution to the bi-objective R8S problem is a set
of systems with non-dominated objective vectors, called
the set of Pareto systems. We exploit the special
structure of the bi-objective problem to characterize
the asymptotically optimal simulation budget
allocation, which accounts for dependence between the
objectives and balances the probabilities associated
with two types of misclassification error. Like much of
the R8S literature, our focus is on the case in which
the simulation observations are bivariate normal.
Assuming normality, we then use a certain asymptotic
limit to derive an easily-implementable Sampling
Criteria for Optimization using Rate Estimators (SCORE)
sampling framework that approximates the optimal
allocation and accounts for correlation between the
objectives. Perhaps surprisingly, the limiting SCORE
allocation exclusively controls for
misclassification-by-inclusion events, in which
non-Pareto systems are falsely estimated as Pareto. We
also provide an iterative algorithm for implementation.
Our numerical experience with the resulting SCORE

pedestrians move along path segments at rates that are
determined by the presence of other pedestrians, and
make their choice of the path segment to cross next at
the intersections of paths. Information about the
topology of the path network and the topography of the
landscape can be expressed as separate functional and
spatial aspects of the model by making use of Carma
language constructs for representing space. We use
simulation to study the impact on the system dynamics

of Collective Adaptive System, which consist of a set
of motes that are spatially distributed in an indoor or

conditions, such as humidity, intensity of light,
temperature, and vibrations, but also collects complex
information, such as images or small videos, and
cooperates with the whole set of motes forming the WSN
to allow the routing process. The traffic in the WSN
consists of packets that contain the data harvested by
the motes and can be classified according to the type
of information that they carry. One pivotal problem in
WSNs is the bandwidth allocation among the motes. The
problem is known to be challenging due to the reduced
computational capacity of the motes, their energy
consumption constraints, and the fully decentralised
network architecture. In this article, we study a novel
algorithm to allocate the WSN bandwidth among the motes
by taking into account the type of traffic they aim to
send. Under the assumption of a mesh network and
Poisson distributed harvested packets, we propose an
analytical model for its performance evaluation that
allows a designer to study the optimal configuration

model is not reversible, we show it to be $ \rho

self-adaptiveness properties to address unforeseen

extremely difficult (if not seemingly intractable) to
engineer reusable pieces of distributed behaviour to
make them provably correct and smoothly composable.
Building on the field calculus, a computational model
(and associated toolchain) capturing the notion of
aggregate network-level computation, we address this
problem with an engineering methodology coupling formal
theory and computer simulation. On the one hand,
functional properties are addressed by identifying the
largest-to-date field calculus fragment generating
self-stabilising behaviour, guaranteed to eventually
attain a correct and stable final state despite any
transient perturbation in state or topology and
including highly reusable building blocks for
information spreading, aggregation, and time evolution.
On the other hand, dynamical properties are addressed
by simulation, empirically evaluating the different
performances that can be obtained by switching between
implementations of building blocks with provably
equivalent functional properties. Overall, our
methodology sheds light on how to identify core
building blocks of collective behaviour and how to

random inputs used to generate replications are
identically distributed and independent within and
across systems, we show that for searches that use the
observed performance of explored systems to identify
new systems, the replications are conditionally

Through simulation experiments, we demonstrate that
reusing the replications taken during search in
selection and subset-selection procedures can result in
probabilities of correct and good selection well below
the guaranteed levels. Based on these negative
findings, we call into question the guarantees of
established ranking-and-selection procedures that reuse

ranking-and-selection procedures after search and
discuss how procedures that only provide guarantees in
the preference zone are ill-suited to this setting.",

chain is required. In this article, we use graph
analysis to obtain this knowledge. In particular, we
focus on knowledge of the shortest paths (in terms of
``rare'' transitions) to the goal state. We show that
only a subset of the (possibly huge) state space needs
to be considered. This is effective when the high
dependability of the system is primarily due to high

high redundancies. For several models, we compare our

abstract = "Processes in computer simulations tend to be highly
repetitive. In particular, parameter studies further
exasperate the situation as the same model is
repeatedly executed with only partially varying
parameters. Consequently, computer simulations perform
identical computations, with identical code, identical
input, and hence identical output. These redundant
computations waste significant amounts of time and
energy. Memoization, dating back to 1968, enables the
caching of such identical intermediate results, thereby
significantly speeding up those computations. However,
until now, automated approaches were limited to pure
functions. At ACM SIGSIM-PADS 2016 we published, to the
best of our knowledge, the first practical approach for
automated memoization for impure code. In this work, we
extend this approach and evaluate the performance
characteristics of a number of extensions that deal
with questions posed at PADS: (1) To reduce and bound
the memory footprint, we investigate several cache
eviction strategies. (2) We allow the original and the
memoized code to coexist via a runtime-switch and
analyze the crossover point, thereby mitigating
memoization overhead. (3) By optionally persisting the
Memoization Cache to disk, we expand the scope to
exploratory parameter studies where cached results can
now be reused across multiple simulation runs.
Altogether, automated memoization for impure code is a
valuable technique, the versatility of which we explore
further in this article. It sped up a case study of an
OFDM network simulation by a factor of more than 80
with an only marginal increase of memory consumption.",

followers' behaviors are calculated based on specific

its generality and effectiveness. The simulation

abstract = "In simulations, probabilistic algorithms, and
statistical tests, we often generate random integers in
an interval (e.g., $[0, s)$). For example, random
integers in an interval are essential to the
Fisher-Yates random shuffle. Consequently, popular
languages such as Java, Python, C++, Swift and Go
include ranged random integer generation functions as
part of their runtime libraries. Pseudo-random values
are usually generated in words of a fixed number of
bits (e.g., 32b, 64b) using algorithms such as a linear
congruential generator. We need functions to convert
such random words to random integers in an interval
($[0, s)$) without introducing statistical biases. The
standard functions in programming languages such as
Java involve integer divisions. Unfortunately, division
instructions are relatively expensive. We review an
unbiased function to generate ranged integers from a
source of random words that avoids integer divisions
with high probability. To establish the practical
usefulness of the approach, we show that this algorithm
can multiply the speed of unbiased random shuffling on
x64 processors. Our proposed approach has been adopted
by the Go language for its implementation of the
shuffle function.",

Interval'' by Lemire (2018) addressed the problem of
reducing the cost of machine instructions needed for
the random generation of integer values in a generic
interval $[0, s)$. The approach taken by the author is
the one of exploiting the rejection method (Neumann
1951) to build an algorithm that almost eliminates the
need for performing integer division operations-the
algorithm still exploits divisions by powers of two,
implemented in the form of cheap shift operations. In
more details, the likelihood of not requiring an
integer division in the proposed algorithm is $2^L - s
/ 2^L$, where $L$ denotes the number of bits used to
represent integer values. The author also presents a
comparative experimental study where the new algorithm,
and its implementation for x86 processors, are compared
with solutions offered by common software libraries for
different programming languages.",

abstract = "Cellular Automata (CA) are discrete simulation models,
thus producing spatio-temporal data through
experiments, as well as stochastic models, thus
generating multi-run data. Identifying temporal
patterns, such as cycles, is important to understand
the behavior of the model. Assessing variability is
also essential to estimate which parameter values may
require more runs and what consensus emerges across
simulation runs. However, these two tasks are currently
arduous as the commonly employed slider-based
visualizations offer little support to identify
temporal trends or excessive model variability. In this
article, we addressed these two tasks by developing,
implementing, and evaluating a new visual analytics
environment that uses several linked visualizations.
Our empirical evaluation of the proposed environment
assessed (i) whether modelers could identify temporal
patterns and variability, (ii) how features of
simulations impacted performances, and (iii) whether
modelers can use the familiar slider-based
visualization together with our new environment.
Results shows that participants were confident on
results obtained using our new environment. They were
also able to accomplish the two target tasks without
taking longer than they would with current solutions.
Our qualitative analysis found that some participants
saw value in switching between our proposed
visualization and the commonly used slider-based
version. In addition, we noted that errors were
affected not only by the type of visualizations but
also by specific features of the simulations. Future
work may combine and adapt these visualizations
depending on salient simulation parameters.",

consequential error: re-seeding the pseudorandom number

data presented by Kim et al. are thus individual
realizations of a random walk and not suited to judge

abstract = "Most pseudorandom number generators (PRNGs) scale
poorly to massively parallel high-performance
computation because they are designed as sequentially
dependent state transformations. We demonstrate that
independent, keyed transformations of counters produce
a large alternative class of PRNGs with excellent
statistical properties (long period, no discernable
structure or correlation). These counter-based PRNGs
are ideally suited to modern multicore CPUs, GPUs,
clusters, and special-purpose hardware because they
vectorize and parallelize well, and require little or
no memory for state. We introduce several counter-based
PRNGs: some based on cryptographic standards (AES,
Threefish) and some completely new (Philox). All our
PRNGs pass rigorous statistical tests (including
TestU01's BigCrush) and produce at least 264 unique
parallel streams of random numbers, each with period
2128 or more. In addition to essentially unlimited
parallel scalability, our PRNGs offer excellent
single-chip performance: Philox is faster than the
CURAND library on a single NVIDIA GPU.",

PRNG must be sufficiently long that the state space of
the PRNG will not be exhausted by any application, even
if run on large parallel machines for long periods of
time. One million cores, generating 10 billion random
numbers per second, will take about half an hour to
generate $2^{64}$ random numbers, which raises doubts
about the long-term viability of a single,
unpararameterized PRNG with a periods of `only'
$2^{64}$. On the other hand, exhausting the state space
of a multistreamable family of $2^{32}$ such
generators, or a single generator with a period of
$2^{128}$, is far beyond the capability of any
technology remotely like that in current computers.''",
remark-2 = "From the article, page 5: ``only a few conventional
PRNGs pass even one complete battery of Crush tests.
The multiple recursive generators, the multiplicative
lagged Fibonacci generators, and some combination
generators are reported to do so. On the other hand,
many of the most widely used PRNGs fail quite
dramatically, including all of the linear congruential
generators, such as drand48() and the C-language
rand(). The linear and general feedback shift register
generators, including the Mersenne Twister, always fail
the tests of linear dependence, and some fail many
more.''",

parallel random-number generation. The authors note
that large internal state (e.g., the Mersenne Twister
needs 2496 bytes) is impractical with a million cores,
or with GPUs that require awkward memory transfers
between GPU and CPU memory. They propose methods that
require little state, and are based on cryptographic
algorithms. They point out that a generator based on
the Advanced Encryption Standard with Intel AES-NI
hardware support becomes competitive with other
generators. The comparative Table 2 on page 8 shows
that the Threefish, Threefry, and Philox generators
require only 0.7 to 4.3 cycles per byte.",

abstract = "We describe a new algorithm SplitMix for an
object-oriented and splittable pseudorandom number
generator (PRNG) that is quite fast: 9 64-bit
arithmetic/logical operations per 64 bits generated. A
conventional linear PRNG object provides a generate
method that returns one pseudorandom value and updates
the state of the PRNG, but a splittable PRNG object
also has a second operation, split, that replaces the
original PRNG object with two (seemingly) independent
PRNG objects, by creating and returning a new such
object and updating the state of the original object.
Splittable PRNG objects make it easy to organize the
use of pseudorandom numbers in multithreaded programs
structured using fork-join parallelism. No locking or
synchronization is required (other than the usual
memory fence immediately after object creation).
Because the generate method has no loops or
conditionals, it is suitable for SIMD or GPU
implementation. We derive SplitMix from the DotMix
algorithm of Leiserson, Schardl, and Sukha by making a
series of program transformations and engineering
improvements. The end result is an object-oriented
version of the purely functional API used in the
Haskell library for over a decade, but SplitMix is
faster and produces pseudorandom sequences of higher
quality; it is also far superior in quality and speed
to java.util.Random, and has been included in Java JDK8
as the class java.util.SplittableRandom. We have tested
the pseudorandom sequences produced by SplitMix using
two standard statistical test suites (DieHarder and
TestU01) and they appear to be adequate for
``everyday'' use, such as in Monte Carlo algorithms and
randomized data structures where speed is important.",

value do not cause bits of the seed to flip; an
approximate proxy for how many bits of the seed will
flip might be the number of bit pairs of the form 01 or
10 in the candidate $\gamma$ value {\tt z}. Therefore
we require that the number of such pairs, as computed
by {\tt Long.bitCount(z ^ (z >>> 1))}, exceed 24; if it
does not, then the candidate z is replaced by the XOR
of {\tt z} and {\tt 0xaaaaaaaaaaaaaaaaL}, a constant
chosen so that (a) the low bit of {\tt z} remains 1,
and (b) every bit pair of the form 00 or 11 becomes
either 01 or 10, and likewise every bit pair of the

necessarily has more than 24 bit pairs whose bits

very fast, good-quality pseudorandom number generators.
Subsequent analysis by Panneton and L'Ecuyer has
lowered the expectations raised by Marsaglia's article,
showing several weaknesses of such generators.
Nonetheless, many of the weaknesses of xorshift
generators fade away if their result is scrambled by a
nonlinear operation (as originally suggested by
Marsaglia). In this article we explore the space of
possible generators obtained by multiplying the result
of a xorshift generator by a suitable constant. We
sample generators at 100 points of their state space
and obtain detailed statistics that lead us to choices
of parameters that improve on the current ones. We then
explore for the first time the space of
high-dimensional xorshift generators, following another
suggestion in Marsaglia's article, finding choices of
parameters providing periods of length $ 2^{1024} 1 $
and $ 2^{4096} 1 $. The resulting generators are of
extremely high quality, faster than current similar
alternatives, and generate long-period sequences
passing strong statistical tests using only eight
logical operations, one addition, and one
multiplication by a constant.",
