description         Message Passing Interface (MPI) Library

long_description    MPICH is a high-performance and widely portable\
                    implementation of the Message Passing Interface (MPI) \
                    standard (MPI-1, MPI-2 and MPI-3). The goals of MPICH are:\
                    (1) to provide an MPI implementation that efficiently\
                    supports different computation and communication platforms\
                    including commodity clusters (desktop systems,\
                    shared-memory systems, multicore architectures), high-speed\
                    networks (10 Gigabit Ethernet, InfiniBand, Myrinet,\
                    Quadrics) and proprietary high-end computing systems (Blue\
                    Gene, Cray) and (2) to enable cutting-edge research in MPI\
                    through an easy-to-extend modular framework for other\
                    derived implementations. \n\
                    \n\
                    The mpich port follows the latest mpich 3.x line, and is \
                    the successor to the mpich2 port. Starting with the major \
                    release in November 2012, the project is renamed back to \
                    MPICH (from MPICH2) with a version number of 3.0.
