Applications of parallel supercomputers: Scientific results and computer science lessons
Parallel Computing has come of age with several commercial and inhouse systems that deliver supercomputer performance. We illustrate this with several major computations completed or underway at Caltech on hypercubes, transputer arrays and the SIMD Connection Machine CM-2 and AMT DAP. Applications covered are lattice gauge theory, computational fluid dynamics, subatomic string dynamics, statistical and condensed matter physics,theoretical and experimental astronomy, quantum chemistry, plasma physics, grain dynamics, computer chess, graphics ray tracing, and Kalman filters. We use these applications to compare the performance of several advanced architecture computers including the conventional CRAY and ETA-10 supercomputers. We describe which problems are suitable for which computers in the terms of a matching between problem and computer architecture. This is part of a set of lessons we draw for hardware, software, and performance. We speculate on the emergence of new academic disciplines motivated by the growing importance of computers. 138 refs., 23 figs., 10 tabs.
