APPLICATION-DRIVEN CONSIDERATIONS FOR THE DESIGN OF A MULTIPLE-PROCESSOR TERAFLOP S COMPUTER-SYSTEM/

Three-dimensional, time-dependent, computational fluid dynamics simula tions in complex geometries are used to outline the computational need s of advanced problems in science and engineering. We discuss how thes e requirements could be met by a teraflop/s multiprocessor supercomput er with integrated visualization facilities. Specifically, we have in mind a parallel/vector/superscalar machine consisting of 64 CPUs. Simp lified benchmarking methods, to be run on existing supercomputers, are proposed to aid the development of such a computer and its system sof tware. Several graphics and operating system software projects for dev eloping the facility are outlined.
