The SPEC OMP2001 Benchmark on the Fujitsu PRIMEPOWER System

The SPEC OMP2001 benchmark suite has recently become available. This suite can be used as a yardstick for measuring and comparing shared-memory systems, which support the OpenMP API. We describe the separate benchmark components in the benchmark suite. We present the results of this benchmark suite on the PRIMEPOWER 2000 system, as officially submitted to SPEC in June 2001. We have run the benchmark on this flat SMP System with up to 128 processors. We analyze the benchmark results. We give some recommendations for an OpenMP programming style.
