Performance comparison of the CRAY-2 and CRAY X-MP/416 supercomputers

Conference ·
DOI:https://doi.org/10.1007/BF00127878· OSTI ID:6728393

The serial and parallel performance of one of the world's fastest general purpose computers, the CRAY-2, is analyzed using the standard Los Alamos Benchmark Set plus codes adopted for parallel processing. For comparison, architectural and performance data are also given for the CRAY X-MP/416. Factors affecting performance, such as memory bandwidth, size and access speed of memory, and software exploitation of hardware, are examined. The parallel processing environments of both machines are evaluated, and speed-up measurements for the parallel codes are given. 14 refs., 2 figs., 9 tabs.
