The Open MPI Project is an open source MPI-2 implementation that is
developed and maintained by a consortium of academic, research, and
industry partners.  Open MPI is therefore able to combine the experise,
technologies, and resources from all across the High Performance
Computing community in order to build the best MPI library available.
Open MPI offers advantages for system and software vendors, application
developers and computer science researchers.

Open MPI represents the merger between three well-known MPI
implementations:
    * FT-MPI from the University of Tennessee
    * LA-MPI from Los Alamos National Laboratory
    * LAM/MPI from Indiana University
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.  Each of these MPI implementations excelled
in one or more areas.  The driving motivation behind Open MPI is to
bring the best ideas and technologies from the individual projects and
create one world-class open source MPI implementation that excels in all
areas.
