Performance results for two of the NAS parallel benchmarks
David A. Bailey, Paul O. Frederickson · 1991
Two problems from the recently published NAS Parallel Benchmarks have been implemented on three advanced computer systems. These two benchmarks are the following: (1) an embarrassingly parallel Monte Carlo statistical calculation and (2) a Poisson partial differential equation solver based on three-dimensiona l fast Fourier transforms. The first requires virtually no interprocessor communication, while the second has a substantial communication re quirement. This paper briefly describes the two problems stud ied, discusses the implementation schemes employed, and gives performance results on the Cray Y-MP, the Intel iPSC/860 and the Connection Machine-2.
