Project Description

The Open MPI Project is an open source Message Passing Interface implementation that is developed and maintained by a consortium of academic, research, and industry partners. Open MPI is therefore able to combine the expertise, technologies, and resources from all across the High Performance Computing community in order to build the best MPI library available.

OLCF staff use Open MPI as a research vehicle for R&D projects based on the MPI standard. Open MPI also serves as the basis for IBM’s Specrtrum MPI product, deployed on OLCF’s SummitDev and Summit systems.
