ResumoThis article describes the performance evaluation through benchmarking of computers with vector-computing capabilities for general-purpose, large-scale scientific computation. This study differs from others in several respects. The author compared three major classes of machines: scalar mainframe computers, mainframe computers, mainframe computers with integrated vector facilities, and supercomputers. He evaluated throughput (measured by total elapsed time) of these machines using a collection of 20 end-user codes. He also measured the speed of execution of each individual code. He recorded the relative ease with which these codes were converted to run, perhaps at less than optimal performance, in each new environment. Finally he attempted to optimize a few of the codes in order to realize the full potential of the particular machine being benchmarked.
