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 scicomp@informatik.tu-muenchen.de 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 http://www5.informatik.tu-muenchen.de/sci-comp/home.html provide a companion archive service in the World Wide Web, including an archive of GSCI digests.

Prentice Date: Fri, 13 Jan 1995 17:07:47 -0700 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. Thanks! John John K.

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 equations. 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 ftp.rus.uni-stuttgart.de in the directory pub/systems/pc/windows/education The software and additional information are compressed with: PKZIP -P -R. Please contact me if you have any questions or problems with UniCalc. Alexander Semenov Novosibirsk Division of the Russian Research Institute of Artificial Intelligence pr.

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.

Tennessee, Knoxville Robert Ferraro/Jet Propulsion Laboratory Geoffrey Fox/Syracuse Univ. WORKSHOP THEME 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 place. WHO SHOULD ATTEND 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. AGENDA 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 are: Traditional Libraries Lennart Johnsson Harvard U & Thinking Machines Corp. Benchmarks/Kernels Tony Hey University of Southampton Algorithm Templates James Demmel UC Berkeley Class Libraries Roldan Pozo NIST Archetypes Dan Meiron Caltech REGISTRATION The facilities will limit attendance to approximately 60 participants, so advanced registration for the workshop is required.
