June 8 --- June 10, 1993

Domaine de Corbeville, Orsay, France

Is it wise to trust the simulation results produced by computers using
finite precision arithmetic ? When a computation takes place in a neighborhood
of a singularity, then the computing error cannot be made small and all the
digits can be wrong~: such computations are said to be ``impossible''.
Is it possible, however, to go beyond this classical view of computation, and
retrieve the meaning which, at first sight, is clouded by computing errors~?

This module presents the latest approaches for studying the reliability
of computer solutions and the robustness of numerical models. Several problems
are addressed. The necessity of distinguishing between various sources of
instability (algorithms, numerical methods, models...) is emphasized.
Moreover, it is known that an underlying singularity may damage seriously the
quality of computations~: the distance to singularity, viewed by the computer
becomes an essential parameter for interpreting computational processes; but
the influence of a singularity can also be dramatically increased under the
variation of certain parameters, such as the departure from normality for
matrix computations, the Reynolds number in CFD, the resistivity in MHD...

We present a qualitative approach for analysing computer results, which provides
insightful information on condition numbers and distances to singularity,
using intensively various graphical tools such as perturbed spectra, level
curves of resolvent...

This module offers about 20 hours of courses, aimed at engineers and researchers
involved in computer simulation. Lecture notes will be provided to all

Subject: Symposia on Massively Parallel Computing and Applications



In 1993 - 1994, CWI (Centre for Mathematics and Computer Science Amsterdam)
and RUU (University of Utrecht) are organising a series of Symposia on
Massively Parallel Computing and Applications.

As far as the computing part is concerned, we are interested in
contributions on the optimization and analysis of generic numerical
algorithms on massively parallel computers. In particular, we think of
iterative methods for large sparse systems of equations, multigrid methods
for various types of PDEs, parallel methods for the solution of ordinary
differential equation, software tools for parallelization, etc.

On the applications side, we seek contributions in fields where optimization
and analysis of numeric and nonnumeric algorithms for massively parallel
computers are instrumental for real progress. In particular we think of
environmental problems, number theory and cryptography, multiple-particle
systems, chemical reactions, computational fluid dynamics,
seismic problems etc.

The following advisory board will assist in the selection of the
Symposium programs:

P. Aerts, Dutch National Computing Facilities Foundation NCF
O. Axelsson, Catholic University Nijmegen
L.O. Hertzberger, University of Amsterdam
P.A.J. Hilbers, Royal Shell Laboratory Amsterdam
P.J. van der Houwen, CWI and University of Amsterdam
W. Loeve, National Aerospace Laboratory NLR
N. Petkov, University of Groningen
M. Rem, Technical University Eindhoven
J.G. Verwer, CWI
H. Wijshoff, University of Leiden
P. De Wilde, Technical University Delft

We intend to organise bi-monthly one- or half-day meetings each of which
will be centred around a class of numerical algorithms or around a coherent
applications field.
The first three dates will be June 4, 1993, Sept. 24, 1993 and Nov. 26, 1993.
The first meeting will be devoted to application of massively parallel
computing in environmental problems.
Refereed proceedings will be published.

Abstracts of possible contributions are solicited now. Please send an
abstract to Herman J.J. te Riele, CWI, Kruislaan 413, 1098 SJ Amsterdam,
The Netherlands (email: and indicate your preference, if any,
for one of the above three dates. The deadline for submission of abstracts
for the meeting of June 4, 1993 is May 1, 1993; for the other two meetings
the deadline is June 1, 1993.
Notification of acceptance for the first meeting will be sent by May 20, 1993,
and for the two subsequent meetings by July 1, 1993.
(For the symposia meetings in 1994 a new call for abstracts will be issued in
due time.)
A limited budget is available for contributors from abroad to partially cover
travel and lodging expenses.

Subject: HPC/Fujitsu Canadian Scholarship

1993 High Performance Computing Scholarships

HPC, the National High Performance Computing Centre, and Fujitsu
Systems Business of Canada, Inc. announce a joint scholarship
program in scientific computing. The objective of the program
is to foster use of high performance computing for scientific
research at Canadian universities. The program emphasizes
scientific, rather than computational, issues. Efficient use of
the computational resources will also be expected from the
participants, but it is not the primary goal of the competition.

The program has two main parts. A number of 1993 HPC High
Performance Computing Scholarships will be awarded, chosen
competitively among the pool of applicants. All HPC Scholarship
awardees will compete for the annual Fujitsu Scholarship. The
Fujitsu Scholarship will reward the most significant scientific
results obtained on the Fujitsu VPX240 by an HPC Scholarship

While the scholarship program is targeted toward graduate
students, both student and research advisor will be named in the
award. In case of a team application, all the members of the
team will be named.

The awards will consist principally in computer time on the
Fujitsu VPX240 Vector supercomputer operated by the HPC Centre
in Calgary. The Fujitsu VPX240 is a single-CPU machine, with a
peak performance of 2.5 GigaFLOPS. It is presently the only
vector supercomputer publically accessible in Canada.

1993 HPC High Performance Computing Scholarships

Scholarships/grants-in-time will be offered, on a competitive
basis, by Fujitsu and the HPC Centre, to graduate students
enrolled in a full-time, degree-granting program in a Canadian
university. Collaborative efforts are also welcome, especially
international collaborations, but the main applicant will be a
graduate student enrolled in a Canadian university. Selected
applicants will be granted access for an extended period of time
to the Fujitsu VPX240 operated by HPC Centre. The exact number
selected will depend upon the quality of the proposals submitted
and the amount of resources being requested.

The scholarships will cover exclusively charges for computer use
at the facility operated by the HPC Centre, in conditions
determined by the HPC Centre, and limited to remaining resources
not sold to commercial customers, actually available on those
facilities. For the 1993 program, the application deadline is
May 4, 1993. Awards will be announced at SS'93, the 1993
Canadian High Performance Computing Symposium. to be held in
Calgary, June 7-9, 1993. Awardees will be granted access to the
VPX240 during a nine months periods starting July 1, 1993. At
their own discretion, the HPC Centre and Fujitsu may extend that
period to June 30, 1994, to participants who request an
extension. 1993 awardees may apply again in the 1994

As a condition for participation, all 1993 awardees agree to
submit a paper summarizing their results for presentation at
SS'94, the 1994 Canadian High Performance Computing Symposium,
and to submit a copy of that paper to the HPC/Fujitsu Scientific
Commission by May 4, 1994. Those papers will serve as the basis
for selection of the Fujitsu Scholarship Award by the
