NA News Digest Now Coming from Oak Ridge
If you look at the mail header for this week's NA News Digest,
you should see that it is coming from Oak Ridge National Laboratory,
and not from Stanford University. As we announced in last week's
digest, all NA-NET services are being moved to Oak Ridge.
Thanks, again, to Gene Golub and Mark Kent who established NA-NET
at Stanford, to Jack Dongarra and Bill Rosener who are now
handling things at Oak Ridge and the University of Tennessee,
and to Sequent Computers, who have provided the na-net and netlib
machine at Oak Ridge. (The Internet mail addresses "na-net.ornl.gov"
and "netlib.ornl.gov" are aliases for "surfer.epm.ornl.gov".)
As the comments in the mail header now indicate, submissions for the
NA New Digest should be mailed to
na.digest@na-net.stanford.edu
Information on NA-NET, including how to join and how to send
individual mail to other members, can be obtained by sending mail to
na.help@na-net.stanford.edu
It doesn't matter what the mail message to na.help actually says; you
will automatically get a reply consisting of last week's annoucement.

Subject: CERFACS Short Course on Parallel Programming
CERFACS
(European Centre for Research and Advanced Training in
Scientific Computation)
Will Organize
An Introduction to Parallel Computing
A three-day advanced short course
Monday 22nd April - Wednesday 24th April 1990
Toulouse, France
AIM OF COURSE
This course on parallel computing will be held at CERFACS, Toulouse from
April 22nd to 24th, 1991 under the auspices of CERFACS.
The course is aimed at scientists in industry and academia who wish to
learn about parallel computing and familiarize themselves through hands-on
experience with a range of parallel computers.
On the first day, some introductory lectures on vector and parallel
architectures will be followed by a more detailed description of the
parallel computers available to students on the course. These will include
a BBN TC2000, an Alliant FX/80 and FX/2812, a TMC Connection Machine CM-2,
an INTEL hypercube, a CRAY 2 and an IBM 3090/VF.
The second day will examine techniques for programming these machines and
tools available to assist in their use. These lectures will be followed by
a discussion of basic numerical algorithms and software.
The final day will address more large scale computing on such
architectures, including the solution of sparse equations, and will provide an
opportunity for students to run their own codes on the machines.
Throughout the course, there will be a strong emphasis on hands-on
experience and it is the intention that students will finish the course
with a basic knowledge of parallelism and how to appreciate, compare, and
use a range of different parallel architectures.

Montpellier, France
Organized by
CNUSC: Centre National Universitaire Sud de Calcul
CNSF: Cornell National Supercomputer Facility
INRIA: Institut National de Recherche en Informatique et en Automatique
IBM
This is the second in a series of biennial symposia, the goal being an
overview of innovations in the high performance computing field. During
the last decade, intensive computing (parallelism, vectorization, and
scalar) has drawn a large audience in the world of engineers and
researchers, particularly in the field of classical computations. This
has opened several "new" perspectives which were impossible to realize
or conceptualize previously.
The main purpose of this meeting is to bring scientists from various
fields together in order to investigate areas such as Architectures of
Supercomputers, Compilers, Algorithms, Computational Methods, Numerical
Applications, etc.
You are invited to submit a paper on one of the following topics:
1) Architectures and parallel algorithms.
2) Tools and numerical methods oriented to parallel/vector computations.
3) Applications on supercomputers:

Subject: World Congress of Nonlinear Analysts
WORLD CONGRESS OF NONLINEAR ANALYSTS
Melbourne, Florida USA
August 19-26, 1992
FIRST ANNOUNCEMENT: The Global Scientific Advisory Committee (GSAC) is
pleased to announce that the First World Congress of Nonlinear Analysts will
be held from Wednesday, August 19 through Wednesday, August 26, 1992 at Florida
Institute of Technology in Melbourne, Florida, USA.
The interest in mathematical analysis of nonlinear phenomena has led to
increased interdependency and cooperation among scientists across traditional
disciplinary barriers, and this collaboration has proved to be rewarding
and stimulating. Also, industrial recognition of using nonlinear mathematical
models for solving problems of technology is increasing because of the fast development of large-scale computers. It is, therefore, clear that the attempt to
understand the nonlinear world will dominate large parts of mathematics in
most areas of science and technology in future years. Thus, there is a
definite need to have a forum, on a global basis, to forge unity in diversity
and for bringing more cooperation and collaboration into the world community
of nonlinear analysts. It is with this spirit we feel that it is desirable
to have, periodically, a world congress.
GLOBAL SCIENTIFIC ADVISORY COMMITTEE: K.J. Arrow, F.E. Browder, K.C. Chang,
R. Conti, K.V. Frolov, J. Hale, K. Ito, W. Jager, T. Kato, M.A. Krasnoselskii,

C. Olech, I. Prigogine, P.A. Samuelson, A.A. Samarsky and M.P. Singh.
SCIENTIFIC PROGRAM: There will be approximately 20 invited expository
addresses covering recent developments in major areas of Nonlinear Analysis
and about 120 invited lectures divided into the following six main sections
that will have subsections:
1. Nonlinear Operators
2. Calculus of Variations and Optimization; Control Theory; and
Systems Analysis
3. Numerical and Computational Aspects; Mathematical Modelling
4. Dynamic Systems
