Two problems from the recently published "NAS Parallel Benchmarks" have been implemented on three advanced parallel 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-dimensional fast Fourier transforms. The first requires virtually no interprocessor communication, while the second has a substantial communication requirement. This paper briefly describes the two problems studied, discusses the implementation schemes employed, and gives performance results on the Cray Y-MP, the Intel iPSC/860 and the Connection Machine-2.
