Description:

MPICH2 is a high-performance and widely portable implementation of the
MPI standard. This release has all MPI-2.1 functions and features
required by the standard with the exeption of support for the
"external32" portable I/O format.

The mpich2 binaries in this RPM packages were configured to use the default
process manager 'MPD' using the default device 'ch3'. The ch3 device
was configured with support for the nemesis channel that allows for
shared-memory and TCP/IP sockets based communication.

This build also include support for using '/usr/sbin/alternatives'
and/or the 'module environment' to select which MPI implementation to use
when multiple implementations are installed.
