description         Message Passing Interface (MPI) Library

long_description    MPICH2 is an implementation of the Message-Passing \
                    Interface (MPI). The goals of MPICH2 are to provide an \
                    MPI implementation for important platforms, including \
                    clusters, SMPs, and massively parallel processors. It \
                    also provides a vehicle for MPI implementation research \
                    and for developing new and better parallel programming \
                    environments.
