    (description
     "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 expertise, 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.")
