**Subject: Non-decomposable Sets of Linearly Dependent Columns**

Problem:

Finding all non-decomposable sets of linearly dependent columns of a matrix.

Our problem is as follows: Imagine you have a matrix A with m rows and

n columns whereby n>m and matrix A has full rank (m) (hence, the null

space of A has a dimension of n-m). We want to find all sets Si of

column vectors of A which fulfill the following two conditions:

* the column vectors contained in each Si are linearly dependent

* the set of Si is non-decomposable in the sense that removing any

of a vector of Si would mean that the remaining vectors of Si are

linearly INdependent.

An example: Given the following 2x4 matrix A:

first row of A: 1 -1 -1 0

second row of A: 0 1 1 -1

You would have the following 3 sets (c1 corresponds to

the first column of A, c2 to the second column and so on):

S1={c1,c2,c4}

S2={c1,c3,c4}

S3={c2,c3}

Please note that S4={c2,c3,c4} would not be a valid non-decomposable set

in our sense, because if vector c4 were removed from Sy, the vectors c2

and c3 would be still linearly dependent.

This can be a higly combinatorial problem for larger matrices. For

example, for a matrix with 91 rows and 109 columns we calculated over

450000 of such non-decomposable sets. The calculation time was over

50 hours (PC, 1.8 MHz). [Our algorithm is based on a tableau where Gaussian

combinations of rows are performed.]

Does anyone have a more efficient algorithm for calculating all these sets

(which are unique for any matrix A)?

Thanks

**Subject: Optimization Problem**

I have an optimization problem posed as follows:

If

{Sum(i=0 to N, i neq k) xi^(1/mi)}+ xk1^(1/2*mk) + xk2^(1/2*mk)

Term1= -------------------------------------------------------------

{Prod( i=0 to N, i neq k) xi^(1/mi)}*(xk1^(1/2*mk))*(xk2^(1/2*mk))

{Sum(i=0 to N) xi^(1/mi)}

Term2= -----------------------

{Prod( i=0 to N) xi^(1/mi)}

xi>0, mi>0 i=0,1,2....N

xk=xk1+ xk2, k=0,1,...N

Given {xi}'s and {mi}'s, which xk has to be selected such that its

components satisfy xk1=rk*xk2, where rk is positive,

So that (Term1-Term2) is maximized

**Subject: MATLAB Package for Singular BVPs in ODEs**

SBVP 1.0 (SingularBVP) is designed to solve first order BVPs for systems of

ODEs with a singularity of the first kind,

y'(t) = M(t)/(t-a) + f(t,y(t)), a < t <= b

B(y(a),y(b)) = 0,

where M(t) is a given nxn matrix and f, B are given nonlinear functions.

The program can also be used successfully to solve standard problems without

singularity.

The underlying numerical method is collocation. The default choice is

collocation at equidistant points, Gaussian points are optional. We control

the global error of the solution, which is estimated using a modified Defect

Correction idea. This global error estimate is the basis for a mesh

selection strategy where the mesh is adapted according to the

equidistribution of the global error. The code is suitable for a wide range

of tolerances. For efficiency, the order of the method is chosen with

respect to the prescribed solution accuracy.

The code is free. The source code and a manual are available at

http://www.math.tuwien.ac.at/~ewa

Follow the link "Software" in the left frame of the homepage.

Suggestions and remarks on functionality and performance of the code are

most welcome.

**Subject: PAPI 2.1 Release**

PAPI 2.1 Release

The Innovative Computing Laboratory at the University of Tennessee has

recently released PAPI 2.1. PAPI is a cross-platform library interface to

the hardware performance counters present on most modern microprocessors.

Hardware counter data have a variety of uses in application and system

performance evaluation and tuning. In addition to library routines,

PAPI defines a common set of performance metrics and maps these

metrics to native events on a given platform. By using PAPI calls and

metrics, the same instrumentation code can be used to collect comparable

performance data across platforms. PAPI has a simple

high-level interface with routines for starting, stopping, and reading

the counters. A more sophisticated low-level level interface supports

interrupt on overflow of a user-specified threshold, statistical profiling,

user-settable options, and native events. All routines are callable from C,

and all high-level and most of the low-level routines are callable from

Fortran. The 2.1 release fully supports software multiplexing

which uses time slicing to allow more events than the number of physical

counters to be counted simultaneously.

PAPI 2.1 supports the following platforms: Cray T3E; SGI IRIX on MIPS

R10K/R12K; IBM AIX on Power3; Linux/x86; Linux/IA64 (Itanium);

Sun Solaris on UltraSparc I-III; Windows NT/2000/XP.

Work on PAPI is supported by NSF PACI, DOE MICS, DOE SciDAC, and DoD HPCMP.

Index

Numerical spectral models of random processes and fields were developed

in the 1970s and have appeared to be very promising for various

applications. Nowadays, the spectral models are extensively used for

stochastic simulation in atmosphere and ocean optics, turbulence theory,

analysis of pollution transport for porous media, astrophysics, and

other fields of science. The book is divided into four chapters, which

deal with scalar spectral models and some of their applications,

vector-valued spectral models, convergence of spectral models, and

problems of optimisation and convergence for functional Monte Carlo

methods. In addition, the monograph includes four appendices, in which

auxiliary information is presented and additional problems are

discussed.

The book is intended for experts in Monte Carlo methods, as well as for

senior and post-graduate students, who are interested in the theory and

applications of stochastic simulation.

SHARCNET POSTDOCTORAL FELLOWSHIP -- McMaster University, Hamilton, Ontario

Applications are invited for a SHARCNET Postdoctoral Fellowship at

McMaster University. This position is supported by SHARCNET, a consortium

of seven Ontario universities and colleges established to promote world

class computational research in critical areas of science, engineering and

business, and comprising clusters of parallel processing supercomputers

designed for high-performance computing. McMaster's superb computational

facility consists of a 112 cpu Compaq alpha cluster (part of a combined

500 alpha cluster) capable of performing 121 billion arithmetic operations

per second, as well as an excellent desk-top computing environment.

The fellowship provides a unique opportunity for a talented recent Ph.D.

recipient in applied statistics or numerical analysis to spend up to two

years engaged in guided research working on large-scale industrial

problems in the nuclear industry, with a limited amount of teaching. The

successful candidate will work under the supervision of Dr. Fred Hoppe,

SHARCNET award holder, collaborating with Dr. Paul Sermer and other

scientists at Ontario Power Generation. Interest in developing and

applying statistical, mathematical, and computational tools in the

solution of hard and practical data analytic problems is essential as

important components of this research include modelling key parameters

related to reactor operations and performance, and developing statistical

techniques for model validation, including large-scale simulation.

Background in one or more of the following areas is necessary:

multivariate analysis, applied regression, computational methods. Working

knowledge of Matlab and Fortran/C required and acquaintance with SAS or

Splus would be an asset.

This fellowship is open to candidates of any nationality and selection

will be based upon the candidate's area of interest and research

potential.
