OpenMP is a relatively new industry standard for programming parallel computers with a shared memory programming model. Given that clusters of workstations are a cost-effective solution for building parallel platforms, it would of course be highly interesting if the OpenMP model could be extended to these systems as well as to the standard shared memory architectures for which it was originally intended.We present in this paper a fully compliant implementation of the OpenMPsp ecification 1.0 for C targeting networks of workstations. We have used an experimental software distributed shared memory system called Coherent Virtual Machine to implement a run-time library which is the target of a source-to-source OpenMP translator also developed in this project.The system has been evaluated using an OpenMP micro-benchmark suite as to evaluate the effect of some memory coherence protocol improvements. We have also used OpenMP versions of three Splash-2 applications concluding in reasonable speedups on an IBM SP2 machine. This also is the first study to investigate the subtle mechanisms of consistency in OpenMP on software distributed shared memory systems.
