The course is aimed at scientists in industry and academia who wish to learn about parallel computing and familiarize themselves through hands-on experience with a range of parallel computers. On the first day, some introductory lectures on vector and parallel architectures will be followed by a more detailed description of the parallel computers available to students on the course. These will include a BBN TC2000, an Alliant FX/80 and FX/2812, a TMC Connection Machine CM-2, an INTEL hypercube, a CRAY 2 and an IBM 3090/VF. The second day will examine techniques for programming these machines and tools available to assist in their use. These lectures will be followed by a discussion of basic numerical algorithms and software. The final day will address more large scale computing on such architectures, including the solution of sparse equations, and will provide an opportunity for students to run their own codes on the machines. Throughout the course, there will be a strong emphasis on hands-on experience and it is the intention that students will finish the course with a basic knowledge of parallelism and how to appreciate, compare, and use a range of different parallel architectures.

During the last decade, intensive computing (parallelism, vectorization, and scalar) has drawn a large audience in the world of engineers and researchers, particularly in the field of classical computations. This has opened several "new" perspectives which were impossible to realize or conceptualize previously. The main purpose of this meeting is to bring scientists from various fields together in order to investigate areas such as Architectures of Supercomputers, Compilers, Algorithms, Computational Methods, Numerical Applications, etc. You are invited to submit a paper on one of the following topics: 1) Architectures and parallel algorithms. 2) Tools and numerical methods oriented to parallel/vector computations. 3) Applications on supercomputers: E-mail: SHPC@FRMOP11.Bitnet Scientific Organizing Committee F.

The interest in mathematical analysis of nonlinear phenomena has led to increased interdependency and cooperation among scientists across traditional disciplinary barriers, and this collaboration has proved to be rewarding and stimulating. Also, industrial recognition of using nonlinear mathematical models for solving problems of technology is increasing because of the fast development of large-scale computers. It is, therefore, clear that the attempt to understand the nonlinear world will dominate large parts of mathematics in most areas of science and technology in future years. Thus, there is a definite need to have a forum, on a global basis, to forge unity in diversity and for bringing more cooperation and collaboration into the world community of nonlinear analysts. It is with this spirit we feel that it is desirable to have, periodically, a world congress. GLOBAL SCIENTIFIC ADVISORY COMMITTEE: K.J. Arrow, F.E. Browder, K.C. Chang, R. Conti, K.V. Frolov, J.
