Subject: A National Software Exchange for the HPCC

To facilitate the development and distribution of software enabling
technologies for high performance computing we have set up a
National Software Exchange (NSE) for the High Performance Computing
and Communications community.

The project has the following goals:

o Wide availability of high-quality, public-domain software for
high performance computers.

o Promotion of software reuse.

o Collaboration and information sharing between
universities, research laboratories, and industry.

o Active participation by Grand Challenge groups and other
research scientists, both in contributing to and in using the NSE.

o Promotion of technology transfer and software capitalization.

A prototype system is in place and can be accessed through the URL:

As an overview to the system, information is provided on the following topics:

Subject: GNU Survey

I thought that some NA Digest readers may wish to respond to the
enclosed survey by Project GNU:

Project GNU of the Free Software Foundation is conducting a survey to
determine the kinds of mathematical software commonly utilized by scientists
and mathematicians. Your answers will help us to determine the programming
tasks we present to our volunteers. This will ultimately result in a more
complete set of math programs and subroutines available as free software.

Please answer the following questions with regard to scientific,
mathematical, and/or statistical software:

1. What packages are commonly used?

2. What programs and subroutines are desired, but not available?

3. What freeware currently exists?

4. Where else can we ask these questions?

Please give as much detail as you can, including package name, author,
language, and where it can be found.

Send responses to

Thank you!

Subject: High Performance Fortran Workshop


High Performance Fortran (HPF) - Four-Day Workshop
October 18 - 21, 1994
At the Swiss Scientific Computing Center, CSCS-ETHZ
Manno (Ticino), Switzerland

Applied Parallel Research (APR), in cooperation with the Swiss Scientific
Computing Center (CSCS-ETHZ), offers a four-day workshop on High Performance
Fortran (HPF). This will be an intensive training session with hands-on
experience using APR's HPF compilation system, xhpf. Attendees are encouraged
to prepare their own application codes for parallelization over a distributed
memory workstation cluster during the workshop.

This workshop will feature a programming tutorial on MPP systems and HPF, and
offer an opportunity to gain experience parallelizing real Fortran
applications using APR's newest parallelization tools. Ample time has been
allocated to allow each attendee, working at their own pace and with the
instructors and CSCS staff, to parallelize and evaluate real benchmark
programs and their own application codes. CSCS will provide access to MPP
systems on which to run parallelized codes.

The instructors will be John Levesque and Richard Friedman of Applied
Parallel Research. The workshop languages will be English and Fortran.

Workshop Outline:

Day 1 Morning
o Distributed Memory Parallel Architectures Overview
o Data vs. Task Parallelism
o SPMD Programming Paradigm

Day 1 Afternoon
o The Fortran 90 Subset in HPF
o HPF Data Distribution Directives
o Extrinsics

Day 2 Morning
o xhpf Batch Parallelizer
o FORGE 90 Distributed Memory Parallelizer (DMP)
o APR's Extensions to HPF

Day 2 Afternoon
o Using APR's Analysis and Parallelization Tools over
CSCS's Parallel Cluster on Tutorial Example Codes

Day 3 Morning
o Data Parititioning and Loop Distribution
o Data Storage Considerations
o Inhibitors to DO Loop Parallelizations

Day 3 Afternoon
o Parallelization of a Simple Grid Relaxation Code

Day 4 All Day
o Parallelization of Attendee's Codes or Other Examples
Using APR's Parallelization Tools.

Spaces in this workshop are limited and will be available on a first come,
first served basis. It is recommended that you reserve a place by contacting
APR as soon as possible. The tuition fee for this four-day workshop will be
$1500 US. A reduced fee of $1250 applies to organizations with active FORGE
licenses. Full payment must be received at APR by September 16, 1994 to hold
a place.

Requests for further information and advanced registration should be directed
to APR at the addresses given below. CSCS will provide lists of recommended
hotels in the area.

Applied Parallel Research, Inc., based in California, is a leading developer

applications. Its FORGE family of tools include interactive FORGE 90 and
Explorer, and the batch automatic parallelizers DPF and XHPF. APR is an
active participant in the High Performance Fortran Forum (HPFF). Further
information about APR and its FORGE products is available over the Internet,

The workshop host, CSCS, the Swiss National Scientific Computing Center, is
part of the Federal Institute of Technology Zurich (ETHZ), and is located in
Manno, near Lugano in the Ticino region of Switzerland. Its basic mission is
to provide computing services and consulting to Swiss universities, research
institutes, and commercial companies. CSCS contributes its own research and
development and education projects in High Performance Computing. This
workshop is part of CSCS' Parallel Computer Systems and Education Laboratory,

o to present the current state of the art in applying wavelet
theory to image processing,

o to explore the application of large-scale scientific
computation, especially massively parallel supercomputers

o to process and compress huge image data,

o to investigate new challenges demanded by new technologies
in medical imaging, HDTV, virtual reality, multimedia, 3D
images, etc.

The expectation is that new research ideas, motivation, appli-
cations, and collaboration will be generated by this meeting.

Subject: Postdoc position in numerical analysis at IPS / ETH Zurich


At the Interdisciplinary Project Center for Supercomputing (IPS)
of the Federal Institute of Technology (ETH) in Zurich, Switzerland,
we anticipate the availability of funding for a two-year postdoc position
linked to a project on iterative methods for solving very large (linear or
nonlinear) systems of equations. We have a special interest in Lanczos-type
methods, but other approaches may be considered too. Principal investigator
is Martin H. Gutknecht, the head of IPS.
The project aims at both theoretical work and at the production of
reliable state-of-the-art software. Applicants should be qualified and
interested in both these aspects of the project. The earliest possible
starting date is October 1, but a postponing of several months is possible.
Partial funding for a graduate student working in the same area may
also become available.
The Interdisciplinary Project Center for Supercomputing (IPS)
was founded in 1988 to support and promote supercomputing at ETH Zurich.
Its service duties include the individual support of supercomputers users
and software developers at ETH, and the occasional organization of courses.
Besides, research in numerical analysis, computational chemistry, computational
physics, and other application areas is performed, partially in cooperation
with other institutes. IPS also has a well equipped visualization lab.
A wide variety of high-performance and parallel computers are
accessible: NEC SX-3, Cray Y-MP, Cray T3D, Paragon, Parsytec, MasPar,
workstation clusters, etc. However, the US Department of Commerce imposes
restrictions on the usage of some of these computers. In particular, accounts
cannot be opened for citizens of the People's Republic of China, Iran, Iraq,
Lybia, North Korea, Syria, Vietnam, countries from the former Soviet union,
and a number of other formerly communist countries.

Applicants should submit their resume by Aug. 31 to

IPS, ETH-Zentrum
CH-8092 Zurich
