Perfect Benchmarks decomposition and performance on VAX multiprocessors

Abstract

The authors present the methods for decomposition and the performance of the Perfect Benchmark suite on two VAX multiprocessors. Results indicate that it was possible to obtain significant performance gains on both VAX multiprocessors, relative to a uniprocessor case. A methodology that can be applied to decompose other existing scientific and engineering applications is proposed. Guidelines for autodecomposing compiler improvements are provided. The authors discuss and quantify the effect of different cache designs on the multiprocessor performance.<>
