Open MPI is a Message Passing Interface (MPI) library project combining technologies and resources from several other projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI). It is used by many TOP500supercomputers including Roadrunner, which was the world's fastest supercomputer from June 2008 to November 2009,[3] and K computer, the fastest supercomputer from June 2011 to June 2012.[4][5]
with contributions from the PACX-MPI team at the University of Stuttgart. These four institutions comprise the founding members of the Open MPI development team.
The Open MPI developers selected these MPI implementations as excelling in one or more areas. Open MPI aims to use the best ideas and technologies from the individual projects and create one world-class open-source MPI implementation that excels in all areas. The Open MPI project specifies several top-level goals:
to create a free, open source software, peer-reviewed, production-quality complete MPI-3.0 implementation
to provide extremely high, competitive performance (low latency or high bandwidth)
to involve the high-performance computing community directly with external development and feedback (vendors, 3rd party researchers, users, etc.)
to provide a stable platform for 3rd-party research and commercial development
to help prevent the "forking problem" common to other MPI projects[6]
Bullx MPI—In 2010 Bull announced the release of bullx MPI, based on Open MPI[7]
Consortiumedit
Open MPI development is performed within a consortium of many industrial and academic partners. The consortium also covers several other software projects such as the hwloc (Hardware Locality) library which takes care of discovering and modeling the topology of parallel platforms.
