1. For User Familiar Parallel Processing The giant leaps taken in recent years in the improvement of computer performance have brought about an enormous enhancement of the scientific research and technology development. Nevertheless, to cope with demands such as extremely large-scale computer simulation or for a further speedup and precision in calculations, it is absolutely necessary to vastly introduce the parallel processing technique on our hands, so that an environment be realized where end-users may freely utilize the parallel computing at its full advantage. The Center for Promotion of Computational Science and Engineering (CCSE) is a new-born department of JAERI, organized in April, 1995, for the purpose of establishing a common technical basis for parallel processing with a goal of contributing to the promotion of advanced computational science and engineering in Japan. CCSE supersedes the former JAERI Information Systems Center and assumes all its responsibilities, too. 2. A Mecca of Supercomputers In early 1996 CCSE introduced the Complex Parallel Computer System (COMPACS) at its Nakameguro site in Tokyo and also installed a system consisting of massively parallel and a vector parallel supercomputers at its Neyagawa site in Osaka. COMPACS is a really unique system composed of five sets of parallel computers of different machine architectures and is to be used in the parallel processing R&D. As of the end of FY 1995 CCSE operates 10 sets of super-computers in total. In addition to these supercomputers three mainframes and numerous servers and terminal equipment constitute the JAERI Computer and Network System which is unparalleled of this kind in the world, in view of its scale and effectiveness.
