DEISA Benchmark Suite

DEISA produced a benchmark suite to help computer scientists assess the performance of parallel supercomputer systems. The benchmark comprises a number of real applications codes taken from a wide range of scientific disciplines. A structured framework allows compilation, execution and analysis to be configured and carried out via standard input files. The codes were chosen as representative of the scientific projects performed on the DEISA supercomputers. The codes and associated datasets were selected for benchmarking systems with peak performances ranging up to hundreds of teraflops, machines which are more powerful than a desktop
