History

MPICH development began in 1992, when a standard for message passing in parallel and distributed computing was still being discussed. MPICH tracked the development of the MPI standard as it evolved. This served dual purpose: to prove that the MPI standard could be implemented as defined, and that it could be done efficiently on all major platforms.

. The CH part of the name was derived from "Chameleon", which was a portable parallel programming library developed by William Gropp, one of the founders of MPICH. In 2001, work began on a new code base to replace the MPICH1 code and support the MPI-2 standard. Until November 2012, this project was known as "MPICH2". As of November 2012, the MPICH2 project renamed itself to simply "MPICH". MPICH v3.0 implements the MPI-3.0 standard. MPICH v4.x implements the MPI-4.x standard. MPICH is one of the most popular implementations of MPI. It is used as the foundation for many other MPI implementations, including IBM MPI (for
