Subject: Question about Intellectual Property Rights
A friend of mine is thinking of taking a tenure track position at a US
department of Mathematics or Computer Science after having worked at a
European institute for a half decade.
He has developed a software package which, although not commercializable
in its current form, may become so in a few years. A similar, but more
restricted, package was licensed to a major European Engineering modeling
Is it true that some universities/colleges automatically have partial
ownership of commercial software or products developed by faculty and
graduate students while at their employ? If so, what is usually
considered benign, and what is "pushing it?" Any advice on what and
who to ask before signing one's life away?
Replies sent directly to me will be summarized. Indicate if you want

Subject: Software to Solve Large Systems of Non-linear Equations
We are graduate students at the departement of Economics at Stanford University.
Our research in general equilibrium economics requires us to solve systems of
upwards of 500 nonlinear equations with the property that the jacobian will be
singular in some subspaces not near the root. We have used routines employing
tensor product terms in the approximation for a Newton method to solve a
smaller system. We would greatly appreciate any suggestions you might have
concerning an appropriate software routine for solving such large systems.
(FORTRAN preferred but not necessarily).
Thank you very much in advance for your help!

Try this easy one:
Separate the sphere into octants. Subdivide each equilateral triangle
into fourths by bisecting the midpoints of each side:
. . . .
. . . .
. . . .
. . . .
The octant subdivision yields 2^3, and each subsequent subdivision yields
2^2. Subdividing the octants 8 times will give you 2^19 or 0.5E+6

Subject: The NetSolve Project
The NetSolve Project http://www.cs.utk.edu/netsolve/
The first public release of NetSolve is now available. NetSolve is a
network enabled solver that allows users to access computational
resources, such as hardware and software, distributed across the network.
The development of NetSolve was motivated by the need for an easy-to-use,
efficient mechanism for accessing computational resources remotely.
Ease of use is obtained as a result of different interfaces, such as
Fortran, C, and Matlab; good performance is ensured by a load-balancing
policy that enables NetSolve to allocate computational resources as
efficiently as possible. NetSolve offers the ability to look for
computational resources on a network, choose the best one available,
solve a problem (with retry for fault-tolerance), and return the answer
to the user.
The software and additional information is available from our home page:
This page provides information about the software release, plus papers and
manuals on NetSolve. If you have any questions, please mail us at
Brief Description of the System
NetSolve has three components: the client, which can be either a
user program or a user interacting with one of the NetSolve interfaces;
the NetSolve agent; and the pool of NetSolve resources. The entry
point into the NetSolve system is the client sending a problem request
to the agent. The agent analyzes this request and chooses a computational
resource. The problem and its input data are then sent to the chosen
NetSolve resource. The problem is solved by the appropriate software
package, and the result is sent back to the client. The system can be
set up on an intranet or over the internet. We have set up an agent and
a number of computational servers that can be used here in Tennessee.

Subject: Gordon Bell Prize for 1997
This is the 10th year of the Gordon Bell Prize for parallel
processing. Although he originally stated that he would fund the
prize for 10 years, Gordon has agreed to continue to offer the prize
until someone sustains at least 1 Tf/s on a real application. The
rules for 1997 are attached. Note that criteria other than raw
performance are considered.
The 1997 Gordon Bell Prizes
The Gordon Bell Prizes recognize achievements in large-scale
scientific computing. Entries for the next Prize are due on 1 May
1997, and finalists will be announced by 30 June 1997. Pending
approval by the Supercomputing '97 program committee, finalists will
be invited to present their work at a special session of that meeting
in November 1997. Winners and honorable mentions will be announced
following the presentations.
The 1997 prizes will be given for work in the following categories:
1. Performance: The entrant will be expected to convince the judges
that the submitted program is running faster than any other
comparable engineering or scientific application. Suitable evidence
will be the megaflop rate based on actual operation counts or the
solution of the same problem with a properly tuned code on a machine
of known performance, such as a Cray Y-MP. If neither of these
measurements can be made, the submitter should document the
performance claims as well as possible.
2. Price/performance: The entrant must show that the performance of
the application divided by the list price of the smallest system
needed to achieve the reported performance is better than that of
any other entry. Performance measurements will be evaluated as for
the performance prize. Only the cost of the CPUs, memory, and any
peripherals critical to the application need be included in the
price. For example, if the job can be run on diskless compute
servers, the cost of disks, keyboards, and displays need not be
3. Compiler parallelization: The combination of compiler and
application that generates the most speed-up will be the winner.
Speed-up will be measured by dividing the wall clock time of the
parallel run by that of a good serial implementation of the same
job. These may be the same program if the entrant can convince the
judges that the serial code is a good choice for a uniprocessor.
Compiler directives and new languages are permitted. However, anyone
submitting an entry in other than a standard, sequential language
will have to convince the judges that the parallelism was detected
by the compiler, not by the programmer.
There are some general conditions:
1. The submitted program must have utility; it must solve a problem
that is considered a routine production run, such as making daily
weather predictions or solving an important engineering or
scientific problem. It should not be a contrived or experimental
problem that is intended just to show high speed-up.
2. Entrants in the price/performance category must demonstrate that
the machine they used has real utility. (No fair picking up a few
used Z-80s for $1 each.) Only list prices of components should be
used. If the machine is not on the market, the entry is probably not
eligible although the judges will consider any reasonable estimate
of the price.
3. One criterion the judges will use for all categories is how much
the entry advances the state of the art of some field. For example,
an entry that runs at 100 Gflops but solves a problem in a day that
previously took a year might win over an entry that runs at 150
Gflops solving a more mundane problem. Entrants who believe their
submission meets this criterion are advised to document their claims
4. In all cases the burden of proof is on the contestants. The
judges will make an honest effort to compare the results of
different programs solving different problems running on different
machines, but they will depend primarily on the submitted material.
Contestants should send a three or four page executive summary to

Subject: New Optimization Technology
We invite to cooperation about the new Optimization Technology.
Our technology is designed for multimeasure (up to 100 and more
variables) optimization practical problems with continuous, breaking
nondifferentiative and stochastic goal functions.
I send you a short list of our optimization technology.
THE NEW TECHNOLOGY OF THE COMPLEX
TECHNICAL SYSTEMS EFFICIENCY INCREASING
At the moment the raise of effectiveness of the complex technical
systems (such as gas-turbine engines, flying vehicles etc.) is reached
by introduction of the new manufacturing technologies, by application of
the new conceptual solutions etc. However, for majority of engineering
systems it is possible to achieve an essential raise of their
effectiveness at the expense of multiparameter (50 and more variables)
and multicriteria optimization and reduction of cost of modernization
For this purpose the unique technology for optimization investigations
has been developed. The technology is oriented to researches, analysis,
search of ways to increase the efficiency and development forecasting of
complex technical systems by means of
- optimum designing of the separate elements and system as a whole;
- optimum matching of the elements, included in the systems;
- determination of the optimum control laws.
during their designing, operational development and modernization. The
technology is based on a new method of indirect optimization on the
basis of self-organizing - IOSO, which has been developed by DSc
The distinctive features of the technology are:
- multicriteria optimization possibility for the problems of large
dimensionality (up to 200 and more variables), that allows to reach the
object's efficiency increasing, which is up to 2...7 times higher than
under traditional optimization methods use.
- low costs for search of the optimum decision (reduction of a time
required for search of the decision up to 20 ...150 times depending on
complexity and dimensionality of a problem;
- multicriteria optimization for the problems in stochastic statement
(up to 100 variables), with a complex topology of the goal functions and
with a plenty of the constraints (the analogues of the decision of
similar problems are unknown);
- decision opportunity for the optimization problems of various classes,
including stochastic, multiextreme and nondifferentiated.
A distinctive feature of the given technology is its high effectiveness
in search for an optimum solution when investigating into technical
systems, modeled at high levels of complexity and hierarchy including
the last achievements in mathematical modeling (2-D and 3-D problems).
In an engine-building the given technology was used for the solution of
the following practical problems (for the "Aviadvigatel",Inc; "Lyulka
Saturn",Inc; SSTC "NK-Engines"; SNECMA, "AutoVAZ"):
1. Determination of the perfection level and analysis of the
possibilities to improve the characteristics of subsonic and supersonic
variable and non-variable axial flow compressors on the basis of the 2-D
axisymmetrical mathematical model (number of variables - up to 99;
number of constraints - up to 220; number of optimization criteria - up
2. Optimum control of aircraft gas-turbine engines for unsteady
operational modes (number of variables - up to 216; number of
constraints - up to 26).
3. Matching of flying vehicle and gas-turbine engine, and definition its
optimal control laws (number of variables - up to 70; number of
constraints - up to 8; number of optimization criteria - up to 2).
4. Reduction of the negative influence of the compressor flow path
erosion on the engine's characteristics.
5. Optimum calibration of the microprocessor control systems of a
automobile engine directly on a test stand for ensuring of a minimum of
the fuel consumption at a given emission level.
6. Definition of the parameters and structure of a covers of the engine
units for ensuring the given optical, thermal and strength
characteristics (number of variables - up to 20, number of constraints -
up to 50).
The technology is invariant as to the objects to be investigated and can
be easily adapted to using mathematical models of different complexity
level applied by design companies when solving a large series of
practical problems in various fields of science and engineering
(mechanical engineering, medicine, chemistry etc).
The more detailed technology description and the examples of its usage
for the aviation engines are cited in the following papers:
