Dates are: Febr. 2nd, April 6th, June 8th, Sept. 7th and Nov. 2nd 1990. Place is CWI Amsterdam, The Netherlands. Attention focuses on new developments in numerical algorithms for parallel computing systems, on software tools for parallel computing (including libraries) and on applications in science and technology (e.g., fluid dynamics, mechanics, chemistry). The organising committee consists of Prof.dr. Th.J. Dekker (UvA), Dr. H.J.J. te Riele (CWI) and Prof.dr. H.A. van der Vorst (TUD and CWI). ABSTRACTS OF POSSIBLE CONTRIBUTIONS TO THE FOURTH AND FIFTH MEETINGS (SEPTEMBER 7th and NOVEMBER 2nd, 1990) ARE SOLICITED NOW. The deadline for submission of abstracts is May 15th, 1990. Notification of acceptance will be sent by June 15th, 1990. Please send abstract to: Herman J.J. te Riele, CWI, Kruislaan 413, 1098 SJ Amsterdam, The Netherlands (email: herman@cwi.nl). A special issue of the IMACS Journal "Applied Numerical Mathematics" will be devoted to the proceedings of the symposia. Contributions will be subject to the usual refereeing process of IMACS. The program for June 8th reads as follows: O. Axelsson (KU Nijmegen): Parallel implementations of algebraic multilevel iteration methods T.L. Freeman (Univ. of Manchester, UK): A parallel variable metric algorithm for unconstrained optimization D. Goovaerts (KU Leuven, Belgie): Parallel implementation of domain decomposed preconditioners K. Potma (Univ. of Amsterdam): Implementing Linear Algebra Algorithms on a MEIKO Computing Surface W.

Hockney, Reading Parallel Architectures G.C. Fox, CALTECH Hypercube Architectures and Applications K.C Bowler, Edinburgh Transputer Machines and Applications J. Richardson, TM Connection Machine and Applications I. Guyon, AT&T Bell Labs Neural Networks and Applications R. Gruber, EPFL Software Development Strategies for Parallel Architectures with Distributed Memory Topics Parallel architectures The course will present an overview on parallel architectures in general with special focus on parallel machines with distributed memory. Strong and weak points of the different types of architectures are critically discussed and compared. Software development environments and tools for parallel architectures are presented and the importance of these tools for the strongly application oriented user is explained. Models describing the performance of parallel architectures with shared and distributed memory architectures are discussed. Software development strategies for parallel architectures After presenting an introduction to numerical modelization in general, the course will discuss the different phases, starting from real experiment, switching to physical and numerical modeling. Special focus is on the adaptation of numerical approaches to modern parallel architectures. Neural networks The course will describe the current state-of-the-art in neural computing. It will not assume prior expertise in neural networks. The six lessons presented will cover machine learning and biological computation, learning rules and implementations for adaptive artificial neurons, neural network systems, applications like pattern recognition and signal processing, and a review of existing software design tools, hardware implementations, neural network journals, books, and conferences. Applications A major fraction of the course is dedicated to the presentation of the successful implementation of a broad spectrum of applications drawn from physics, engineering, computer science and other areas. The usefulness of the distinct types of parallel architectures for a collection of very CPU-intensive applications is compared, and, depending on the type of architecture, concrete techniques are presented, by means of which these applications can be mapped to the hardware in an optimal fashion. Organization During the five days of the course, there will be six hours of lectures each day, supplemented by informal discussion sessions during the day and in the evening. A detailed program and abstracts of the lectures will be issued to those attending. The full collection of the written versions of the lectures will become available at the time of the summer course. The proceedings will be published in a special issue of Computer Physics Reports.
