The performance of two second-generation supercomputers, the NEC SX-3 and the Fujitsu VP2600, is analyzed using the Standard Los Alamos Benchmark Set, the Mendez Fluid Dynamics Codes, and some highly vectorizable production-type codes from Los Alamos. For comparison, data are also given for a single processor of the CRAY Y-MP8/264. Factors affecting performance such as memory bandwidth, vector register organization, and the effects of multiple vector pipelines are examined. On a highly vectorizable code that can take advantage of multiple vector pipes, the SX-3 and VP2600 are faster than the single CRAY Y-MP processor by factors of seven to eight.
