The Computing and Communications Division at the Los Alamos National Laboratory has designed and is building a parallel microprocessor system (PuPS) to serve as a research tool for evaluating parallel processing of large-scale scientific codes. PuPS is an experimental architecture consisting of an orthogonal array of 20 processing elements by 32 memory elements, establishing a tightly coupled, shared-memory (16-Mbyte) machine. The hardware incorporates VLSI components, such as 16-bit microprocessors, floating-point co-processors, and dynamic random access memories. The design replaces conventional MSI/SSI circuitry with programmable array logic, logic sequencers, and logic arrays. This experimental system, which is only 1 element of the parallel processing research being done by the Laboratory's Computing and Communications Division, will enable direct comparisons of speedups of algorithms for a variety of multiprocessor architectures.
