description         A High Performance Message Passing Library
long_description    Open MPI is a project combining technologies and resources \
            from several other projects (FT-MPI, LA-MPI, LAM/MPI, and \
            PACX-MPI) in order to build the best MPI library available. A \
            completely new MPI-2 compliant implementation, Open MPI offers \
            advantages for system and software vendors, application developers \
            and computer science researchers.

# Since mpi is just a compiler wrapper, compiling it as universal needs to be
# supported upstream since it'd be a constantly moving target, for reference
# see, https://trac.macports.org/ticket/20240
