mpich

Portable implementation of MPI-1, MPI-2 and MPI-3

MPICH is an implementation of the Message-Passing Interface (MPI) standard. The goal of MPICH is to provide an MPI implementation that supports different computation and communication platforms including commodity clusters, high-speed networks and proprietary high-end computing systems. It also enables cutting-edge research in MPI through an easy-to-extend modular framework for other derived implementations. See also <https://github.com/pmodels/mpich>.
