Dear na-neters,

I am interested to find all the values for which a system

of the form:

Ax = cBx + (c*c)Dx,

where A,B and D are complex matrices, while c the (complex)

parameter, becomes degenerate. Any suggestions referring

to the numerical handling of these problems would be greatly

appreciated.

Thank you very much for your consideration and time.

**Subject: Help on Block Jacobi Method for SVD**

Hello,

I'm a DEA student of Grenoble and I'm doing a stage in the LMC laboratory.

I'm working on the SVD problem, and I would like to have some informations on

the block Jacobi method. More precisely, I can't find the computation of the

2*2 subproblem: compute Xij (a 2m/l*2m/l matrix) and Yij (a 2n/l*2n/l matrix),

where l is the number of blocks such that:

t [ Aii Aij ] [ Dii 0 ]

Xij [ ] Yij = [ ]

[ Aji Ajj ] [ 0 Djj ]

I know this is done in: Bishof & Van Loan "Computing the singular value

decomposition on a ring of array processors" (Large Scale Eigenvalue Problems,

Cullum & Willoughby eds, North-Holland, Amsterdam, 1986, p.51-66);

but I can't find this article.

Maybe someone can help me?

Manuel Matencio.

**Subject: RKTEC v2.1 Available**

RKTEC version 2.1 is now available. This is an ANSI C program for

computing truncation error coefficients of Albrecht's error expansion

for Runge-Kutta formulas. Albrecht's expansion is equivalent to

Butcher's but uses a different basis of elementary differentials and

enjoys some advantages over the classical approach.

With version 2.1 a radial stability region "plotter" has been added,

making the tool more convenient for formula comparison. For formula

derivation a Maple version is in the works. Let me know if you're

interested in the Maple version. (If there is sufficient interest

I will devote more time to it.)

Version 2.1 should be available from Netlib shortly. At present it can

be obtained by anonymous ftp to math.niu.edu in pub/papers/Hosea or by

gopher to math.niu.edu in the "Hosea" directory under "Faculty

Publications". The ANSI C source code (rktec21.c) and an MS-DOS

executable (rktecexe.uue) are there as well as a couple of related

preprints.

**Subject: High Level Numerical Computations Package**

I thought na-net readers might like to know of a public-domain

numerical computations package that I recently stumbled across. It's

called "Octave" and is distributed under the terms of the GNU General

Public License.

The program is similar in style to Matlab, using Gnuplot for graphical

output. The underlying numerical solvers used by the program are the

BLAS, LAPACK, LINPACK, ODEPACK etc

The latest released version of Octave is available via anonymous ftp

from ftp.che.utexas.edu in the directory /pub/octave. Complete source

and binaries for several popular systems are available.

**Subject: Adaptive Simulated Annealing**

Adaptive Simulated Annealing (ASA) version 3.13

The latest Adaptive Simulated Annealing (ASA) code and some related

(p)reprints can be retrieved via anonymous ftp from

ftp.alumni.caltech.edu [131.215.139.234] in the /pub/ingber directory.

A new OPTION now collects data during the global optimization process

to importance-sample the user's variables.

The latest version of ASA, ASA-x.y (x and y are version numbers), can

be obtained in several formats. ASA-shar.Z is a compress'd shar'd file

of the current code. For the convenience of users who do not have any

uncompress/gunzip utility, there is a file ASA-shar which is an

uncompress'd copy of ASA-shar.Z; if you do not have sh or shar, you

still can delete the first-column X's and separate the files at the

END_OF_FILE locations. There are tar'd versions in compress and gzip

format, ASA.tar.Z and ASA.tar.gz, respectively. There also is a

current zip'd version, ASA.zip, in which all files have been processed

through unix2dos. Directory /pub/ingber/0lower.dir contains links to

these files for some PC users who may have difficulty with upper case.

Sorry, I cannot assume the task of mailing out hardcopies of code or

papers. My volunteer time assisting people with their queries on my

codes and papers must be limited to electronic mail correspondence.

To get on or off the ASA_list e-mailings, just send an e-mail to

asa-request@alumni.caltech.edu with your request. Update notices are

sent to the ASA_list about every month or two, more frequently if

warranted, e.g., in cases of important bug fixes; these notices are the

only e-mail sent to the ASA_list.

Research Opportunities Parallelizing ASA and PATHINT

I am looking for one to several people with experience parallelizing C

code, e.g., on Crays, to work on parallelizing two specific

algorithms: (a) Adaptive Simulated Annealing (ASA), and (b) an

algorithm to calculate the time-development of multi-variable nonlinear

Fokker-Planck-type systems, using a powerful non-Monte Carlo path

integral algorithm (PATHINT). Some code and papers dealing with these

algorithms can be obtained from ftp.alumni.caltech.edu

[131.215.139.234] in the /pub/ingber directory.

I am PI of an award of Cray time on an NSF Supercomputer, and have

ported these codes successfully onto a C90. However, I am short of

time to further optimize these codes, which is an essential requirement

before doing production runs on C90 and T3D Crays. If necessary, I

will do this work myself, but I would rather share the work,

experience, and research with other interested people who also can

expedite these projects. All code will remain under my copyright under

the GNU General Public License (GPL), i.e., the least restrictive

Library GPL.

There are several immediate projects that are just waiting for detailed

calculations, using codes which already run on SPARCstations, but need

the power of supercomputers for production runs. All results of these

studies will be published in peer-reviewed scientific journals, and

only active participants on these projects will be co-authors on these

papers.

Examples of these projects include:

neuroscience

EEG correlates of behavioral states

short-term memory modeling

realistic chaos + noise modeling

financial applications

2- and 3-state term-structure security calculations

testing of trading rules

nonlinear modeling

persistence of chaos in the presence of moderate noise

If you are interested, please send me a short description of projects

you have worked on, and how many hours/week you are prepared to commit

to these projects for at least a period of 6-12 months.

**Subject: Supercomputer in Bangalore**

SCIENTIFIC SUPERCOMPUTING IN BANGALORE

A state-of-the-art supercomputer recently became operational in

Bangalore at the CSIR Centre for Mathematical Modelling and

Computer Simulation (C-MMACS). The system is an aircooled

supercomputer of the CONVEX C3800 series which is unique in its

use of advanced technology gallium arsenide gate arrays. The

system comprises of two CPUs, a main memory of 512 Mbytes and a

disk capacity of 34 GBytes. It is rated at 240 peak Mflops in 64-

bit and 480 peak Mflops in 32-bit computations. The C-MMACS

system has compilers which offer automatic interprocedural

optimisation, vectorisation and parallelisation. It also has a

powerful application visualisation system. The shared memory

vector processor architecture of the CONVEX supercomputer at C-

MMACS results in several advantages, namely, excellent

performance in large scientific problems which require

vectorisation, parallelisation and optimisation, availability of

proven mature compilers, and what is probably the most important

from the view point of users, extremely easy parallel

programming.

The CONVEX Computer Corporation, USA supplied the supercomputer

through WIPRO Infotech Ltd. The recent liberalisation of US

export control regulations made it possible to import this high

performance computer without any strings.

C-MMACS (pronounced see-max) was established by the Council of

Scientific and Industrial Research (CSIR) in 1988, with a view to

catalyzing, supporting, and strengthening the wide gamut of

scientific programmes in its laboratories. These programmes are

aimed at providing creative new approaches to the design and

analysis of complex systems through mathematical modelling and

computer simulation of their behavioural responses and evolving

structures. C-MMACS is located in the campus of the National

Aerospace Laboratories and it is headed by Dr.K.S.Yajnik. Its

primary objective is to develop and provide expertise and

facilities for modelling and simulation of a wide class of

natural and engineering systems that constitute the core of many

contemporary problems in science and technology. C-MMACS is

governed by a Management Committee under the chairmanship of

Prof. S.K. Joshi, Director General of CSIR.

Scientists at C-MMACS, National Aerospace Laboratories and

several other institutions, who have used the CONVEX

supercomputer at this centre, have found its performance and

capabilities highly satisfying - indeed exciting. They have

discovered that highly complex simulations in areas as widely

different as aerodynamics and molecular modelling, which require

massive computing, have now become possible in an acceptable

timeframe, thereby opening a new era of high-end scientific

computing in India.

**Subject: ICIAM 95, Congress Announcement**

THE THIRD INTERNATIONAL CONGRESS ON

INDUSTRIAL AND APPLIED MATHEMATICS

July 3 - 7, 1995

HAMBURG, GERMANY

The congress organizers are developing a programme that will focus

worldwide attention on the importance of mathematical and computational

methods in the solution of real world problems. A major exposition of

computer hardware and software exhibits and demonstations will enable

you to explore state-of-the-art technology.

In addition to a programme highlighting important advances in research

and applications, there will be many opportunities for you to meet your

colleagues from other countries.

The first International Congress on Industrial and Applied Mathematics

was held 1987 in Paris. ICIAM 87 attracted eighteen hundred scientists

from applied and computational mathematics and applied sciences. This

number climbed to over two thousand at ICIAM 91 in Washington, DC.

ICIAM 95 will be hosted by GAMM.

ICIAM 95 President is Oskar Mahrenholtz,

A minisymposia is a session of speakers focusing on a single topic. The

organizer of a minisympoisium invites the speakers and decides on the

topic they are to deliver. If you would like to organize a minisym-

posium, you must submit a proposal on an ICIAM 95 minisymposium form.

To obtain a form and guidelines for submitting a minisymposium proposal,

please send a message to:

**Subject: Postdoc Position at INRIA**

10-MONTH POST-DOCTORAL POSITION AT INRIA/IRISA

Scientific computing group

Rennes, France

Applications are called for a post-doctoral position at INRIA/IRISA

in parallel scientific computing. The position will be open

in September 1994 for 10 months.

This award is funded by a european grant (Human Capital and Mobility)

and is available ONLY for CITIZENS from the EUROPEAN COMMUNITY (CEE)

who are NOT FRENCH.

Applicants must have a Ph-D in Applied Mathematics, Computer Science

or a related field.

IRISA is a joint institute of INRIA-Rennes (the head is at Rocquencourt),

CNRS (associated laboratory), the University

(Computer Science department) and INSA (Computer Science department).

The group called "Advanced Algorithms for Scientific Computing"

studies numerical algorithms which should be both parallel and

numerically reliable. The domains of interest cover linear algebra

on sparse matrices and differential equations. Of special concern

are the projection methods using Krylov subspaces.

The algorithms are applied to large numerical simulations as

for example Computational Fluid Dynamics. The project is also

interested in programming environments for scientific computing.

The team is leaded by B. Philippe and is composed of about

10 persons.

The HCM contract is coordinated by the CERFACS (Toulouse, France)

and involves 9 institutes from France, Italy, GB, Switzerland,

Belgium, Sweden. It is entitled

"A modular approach to research in computational fluid dynamics,

iterative methods and high performance computing."

The IRISA (INRIA-Rennes) part is devoted to the application

of the Newton-GMRES algorithm to discretisations of the steady

Navier-Stokes equations as well as to implicit time-stepping

schemes. The procedure can be seen as an approximate Newton

algorithm which is matrix-free.

The candidate selected will work on this subject and related issues.

Salary : 14,764 French Francs per month (out of charges).

Applicants should send their CV, the names of 2 referees and a

brief description of research interests.

Applications will be considered until 15 JUIN 1994, along with

already received applications.

ONLY EUROPEAN CITIZENS FROM THE CEE WHO ARE NOT FRENCH ARE

ALLOWED TO APPLY.

Electronic submission is preferred. Letters should be addressed to

Subject: Addendum to V. 94, # 23

Hi all--

The NA Digest we sent out yesterday started off with a note about

SIAM's Ed Block, who is in the hospital. The SIAM office has

asked that we NOT call Ed at the number given in the note.

They say Ed would be very pleased to hear from all of his friends,

but only in writing for now.

Sorry, Ed. Get well soon. Hope to see you in San Diego next month.
