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 tool for MPI implementation research and for developing new and
better parallel programming environments. MPICH2 replaces MPICH1. [
