Shared memory vs.message passing:the COMOPS benchmark experiment

摘要

This paper presents the comparison of the COMOPS benchmark performance in MPI and shared memory on three different shared memory platforms:the DEC AlphaServer 8400/300,the SGI Power Challenge,and the HP-Convex Exemplar SPP 1600.The paper also qualitatively analyzes the obtained performance data based on an understanding of the corresponding architecture and the MPI implementations.Some conclusions are made for the inter-processor communication performance on these three shared memory platforms.
