MPICH is a high-performance and widely portable implementation of the MPI-3.1 standard from the Argonne National Laboratory. It efficiently supports different computation and communication platforms including commodity clusters, SMPs, massively parallel systems, and high-speed networks. This release has all MPI 3.1 functions and features required by the standard with the exception of support for the "external32" portable I/O format and user-defined data representations for I/O.

This package includes the program binaries necessary to run MPICH programs.
