Subject: Announcement of the GSCI Digest

Announcement of the GSCI Digest

GSCI is the monthly newsletter of the special interest group
'Scientific Computing' of the Deutsche Mathematikervereinigung (German
Mathematical Association). However, GSCI is of course completely open
to anyone who is interested in scientific computing.

GSCI will accept and and distribute information which is of interest to
the scientific computing community, including announcements of books
and papers, workshops and conferences, job opportunities, mathematical
software and tools. Unlike other newsletters (like NaNet, Wavelet
Digest, MgNet, Opt-Net, SIAM's SC-Net, etc) the scope of GSCI is
scientific computing in general, including mathematics, applications
and computer science. Like the Belgian SCME digest, GSCI focuses on
topics of regional (German) interest. It will therefore accept
contributions in English or in German.

To be included in the permanent distribution list (which will
replace the present preliminary one), please send a message to
Anyone interested, in particular also students and colleagues in
industry are invited to participate and subscribe to the GSCI digest.

If you have information which may be of interest to the
scientific computing community, please do not hesitate to send it to
the address given above.

Finally, please note that the German Scientific Computing Pages at URL
provide a companion archive service in the World Wide Web,
including an archive of GSCI digests.

Subject: Collecting Information about Simulation Codes

I am writing a chapter on simulation tools for a book on computational
science (part of the D.O.E. CSEP project). This chapter deals with
the use of computer simulation codes for doing science. For example,
codes such as GAUSS, Spice, and DYNA. Part of the chapter will be
a survey of the simulation codes that are widely used in different
fields. Toward that end, I am collecting information from scientists
about what simulation codes they regularly use in their own research.
If you know of or use simulation codes in your research, I would much
appreciate a note about what code or codes you use. How do these
codes fit into your research and how important are they to your work?
Do they take the place of having to write your own simulation codes,
or merely supplement codes you develop yourself? Also, any information
about who produces the code and a contact name and phone number
(or e-mail address) would be very valuable. If you have information
about the codes I mentioned (GAUSS, Spice, and DYNA), I would appreciate
that too since I am not personally that familiar with them.

To clarify what I mean by simulation codes, I am thinking of codes
for modeling physical phenomena in a general way but targeted at
a specific field. For example, codes for doing general molecular
structure calculations, codes for modeling the structural response
of arbitrary solids (buildings, bridges, cars, whatever), or
codes for modeling groundwater flow. I am excluding from this
definition codes such as MATLAB, Maple, and Mathematica which
are not really physical simulation codes but rather general
mathematical tools.

Subject: UniCalc Solver

In the Russian Institute of Artificial Intelligence a mathematical
problem solver UniCalc is developed, based on a combination of
interval mathematics and an artificial intelligence field called
"constraint propagation". It is designed to handle arbitrary systems
of algebraic and algebraic-differential equations and inequalities,
possibly with imprecise or interval data. Important features of
UniCalc are that it does not require transforming the initial problem
to an another form more easy to solve and specifying an initial
approximation for systems of arbitrary complexity. UniCalc can handle
both real-valued and integer-valued problems, as well as problems
involving variables of both types. UniCalc is a multi-windowed
integrated environment including an editor, setup facilities, interval
graphics, symbolic differentiation subsystem, and a set of built-in
methods for solving differential equations.
The following types of problems can be solved with UniCalc: linear
and nonlinear systems of equations and inequalities, problems with
imprecise or interval data, integer-valued problems, optimization
problems, systems of differential and algebraic-differential
At present, versions of UniCalc have been implemented for IBM PC
compatible computers running MS DOS or MS Windows.

The demo-version of UniCalc (without graphics and differential
equations) for MS DOS is placed in the anonymous ftp area of site

in the directory


The software and additional information are compressed with:

Subject: EPA Graduate Student Fellowships

1995 Graduate Student Fellowships
Sponsored by the
U.S. Environmental Protection Agency

The U.S. Environmental Protection Agency (EPA) invites
applications for graduate fellowships in academic disciplines at
the forefront of environmental science and technology: the
physical, biological, and social sciences; mathematics and
computer science; and engineering. These fellowships are
intended to help defray costs associated with advanced
environmentally-oriented study leading to the masters or doctoral
degree. EPA expects to award approximately 100 new multi-year
graduate fellowships in 1995.


The mission of the EPA is to provide leadership in the nation's
environmental science, research, education, and assessment
efforts; make sound regulatory and program decisions; and carry
out effective programs and policies to improve and preserve the
quality of the national and global environment. Science and
technology are central to virtually every aspect of environmental
protection and seem certain to take on progressively greater
importance during the foreseeable future.


Applicants must be citizens of the United States or its
territories or possessions, or lawfully admitted to the United
States for permanent residence.

EPA graduate fellowships are intended for students already
enrolled into a full-time graduate program at an accredited U.S.
college or university.

Women, minorities, and disabled students who are pursuing
graduate degrees in one of the eligible fields are especially
encouraged to apply.


The term of a graduate fellowship is negotiated with students and
ordinarily covers a period of 9 to 12 months for each fellowship
year; funds for unutilized months are forfeited. Students
seeking a masters degree are supported for a maximum period of
two years; students seeking doctoral degrees are supported for a
maximum period of three years.


The Graduate Fellowship Program provides up to $34,000 per year
of support. A maximum of $68,000 will be provided for masters
fellows (2 years) while doctoral fellows can receive up to
$102,000 in support (3 years). Individuals accepting this
support may not concurrently hold other Federal scholarships,
fellowships, or traineeships. The $34,000 annual support covers
stipend, tuition, and expenses as follows:

Stipends during 1995-96 will be $17,000 for 12-month
tenures and prorated monthly at a maximum of $1,417
for shorter periods. Stipends are paid directly to
the Fellow. At its discretion, each fellowship
institution may supplement a Fellow's stipend from
institutional funds in accordance with the supple-
mentation policy of the fellowship institution.

Tuition support will be up to $12,000 per year,
depending upon the policies of the fellowship
institution, paid directly to the institution.

An expense allowance of up to $5,000 (paid to the
institution) will be provided for the direct benefit
of the Fellow, e.g., for health insurance, books,
supplies, and travel to scientific meetings.


Each applicant will be evaluated in terms of his/her potential
for successful graduate study, as evidenced by academic records,
faculty recommendations, and career goals and objectives.
Applicants pursuing a masters degree will be evaluated further on
their outlined plan of study and/or proposed thesis research.
Applicants pursuing the doctoral degree will be evaluated further
on the technical merit of their plan of proposed dissertation
research and its relevance to the EPA mission. Panels of
scientists, mathematicians, and engineers selected by EPA will
perform the reviews.

Subject: Multigrid Course 1995

GMD - Multigrid Course 1995
April 24 - 28, 1995
Bad Honnef near Bonn, Germany

The GMD (The German National Research Center for Computer Science)
will give a multigrid course on April 24 - 28, 1995 at Bad Honnef near Bonn,

The principal lecturer is Professor Achi Brandt from the Weizmann
Institute, Rehovot, Israel, one of the pioneers of multigrid.
The other lecturers are members of the GMD multigrid research group.
The topics of this course will cover the basic principles of
multigrid, recent developments and applications.

The main scope of the course is to provide with an understanding of multigrid.
The visitor will, at the end of the course, be able to write a multigrid
program for model problems. Additionally, the course will supply with an
overview of multigrid application and recent research activities.
The course is especially designed for all those which have to solve partial
differential equations in practice.

For scalar linear elliptic model problems the efficiency of multigrid
algorithms was established at the very beginning of multigrid research.
These methods turned out to be the most efficient techniques for
solving elliptic partial differential equations. The theory states that
a multigrid solution is generally obtained in a time directly proportional
to the number of unknowns on serial computers.
The inherent locality of the multigrid components allows a very efficient
parallelization with nearly optimal speed up.

Multigrid, or more general multilevel computational methods
have evolved into an independent discipline by itself,
interacting with numerous engineering application areas and impacting
fundamental developments in several sciences. The recent past
shows an increased development of multilevel solvers for various areas,
including: aerodynamics, atmospheric and oceanic research, structural
mechanics, quantum mechanics and VLSI-Design.

of Pumps in Olomouc for his thesis Numerical solution of
incompressible viscous fluid in parts of a hydraulic machine by
the finite element method.

The prize as well as the diplomas will be awarded every year and
they are connected with a financial support.

The prize was established by an outstanding Czech mathematician
Ivo Babuska. He was born in Prague in 1926 and after
graduating from the Faculty of Civil Engineering of the Czech
Technical University in Prague he started his work in the
Mathematical Institute of the Czechoslovak Academy of Sciences.
He was appointed professor at the Charles University in Prague
in 1968 and since fall 1968 he has been working at the
University of Maryland, College Park, MD (U.S.A.) where he was
appointed professor.

His scientific work is focused on numerical and applied
mathematics and computational mechanics, and their use in
practice. His results in the finite element method belong to
the fundamentals of the method. He is the author of several
monographs and has initiated several famous scientific meetings
both in Europe and the United States. He established the
journal Applications of Mathematics (formerly Aplikace
matematiky) in 1956. Last year he was awarded the G. Birkhoff
Medal. He was also awarded the degree of Doctor of Science
Honoris Causa by the University of Westminster in London in

Subject: Templates Workshop

February 6, 1995
The Fifth Symposium on the Frontiers of Massively Parallel Computing
sponsored by the IEEE
McLean Hilton, McLean, VA
Jack Dongarra/Univ. Tennessee, Knoxville
Robert Ferraro/Jet Propulsion Laboratory
Geoffrey Fox/Syracuse Univ.

The term "Templates" has recently gained attention in the parallel
processing community, yet is an evolving concept with several definitions.
The primary motivation for constructing templates is to rapidly infuse
into common usage state-of-the-art algorithms in a form which can be
adapted to specific application requirements. This implies that the
template retains the desired numerical properties but is cast in a form
which is independent of parallel architecture, data layout, and programming
language. Many users would like to see templates go beyond pseudo-code,
which can be found in textbooks and research papers, to become objects
which are directly compilable on multiple architectures. This workshop will
explore the issues involved in constructing an algorithm template which is
portable, scalable, and adaptable to application requirements, yet retains
the numerical properties which make the algorithm desirable in the first

The success of this workshop will depend on the participation of a mix of
scientists who write parallel applications, parallel numerical algorithms
researchers, and parallel programming environments researchers. Persons from
these communities with an interest in portability, pedagogy, and maximizing
reusability of parallel algorithms are invited to attend. Computational
scientists are particularly encouraged to voice their requirements.

This is a half-day workshop in conjunction with Frontiers '95, consisting
of invited presentations and an open discussion among all participants.

To properly explore the workshop theme, the organizers have invited experts
in certain topics to address the problems applications writers face in
1) constructing portable parallel applications, 2) using "state of the art"
parallel algorithms, and 3) reusing "state of the art" numerical methods
developed by others or for different applications. The invited presentations

Oxford University Computing Laboratory consists of three main groups,
the Programming Research Group, the Numerical Analysis Group and
Oxford Parallel. It is a full academic department of the University and
at the present time there are twenty-seven academic staff, forty-five
research officers and sixty-five doctoral students, engaged in teaching
and carrying out research in computing science and numerical analysis.

Oxford Parallel, the Parallel Applications Centre of the University of
Oxford, has developed a parallel time domain electromagnetic code
which is capable of delivering broadband RCS predictions on
unstructured meshes for scatterers with complex geometries and is about
to begin new work aimed at improving the handling of boundary
conditions in such problems.

We seek someone with strong mathematical ability and some experience
in one or more of the following areas:

* electromagnetic computations
* numerical solution of pde's
* finite element or finite volume methods on unstructured
tetrahedral meshes
* absorbing boundary conditions.

The ideal candidate will already be a good Fortran programmer with
experience of parallel programming, but we will provide training in
these aspects if necessary.

We seek a Research Officer, preferably with a PhD or MSc in some
aspect of computation, who is able to express the fruits of their research
in practical form.

Salary be on the experience related RS1A scale, currently #13,941 to
#20,953 per annum.

Applications, stating the post being applied for, should be in the form of
a full curriculum vitae together with the names of two referees. They
should be sent to arrive before the closing date of 25th January 1995, to:
