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.
