%description
MPICH is a high performance and widely portable implementation of the Message
Passing Interface (MPI) standard.

The goals of MPICH are:

 * 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 and proprietary high-end computing systems
   (Blue Gene, Cray)
 * to enable cutting-edge research in MPI through an easy-to-extend modular
   framework for other derived implementations

MPICH is a freely available, portable implementation of MPI, the
Standard for message-passing libraries. This package contains manpages,
headers and libraries needed for developing MPI applications.

This RPM contains the static library files, which are packaged separately from
the dynamic library and headers.
