Performance comparison of the Cray-2 and Cray X-MP/416
Margaret L. Simmons, Harvey J. Wasserman · 2003
The serial and parallel performance of 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 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 speedup measurements for the parallel codes are given.>
