==Official implementations==

* The initial implementation of the MPI 1.x standard was [[MPICH]], from [[Argonne National Laboratory]] (ANL) and [[Mississippi State University]]. [[IBM]] also was an early implementor, and most early 90s [[supercomputer]] companies either commercialized MPICH, or built their own implementation. [[LAM/MPI]] from [[Ohio Supercomputer Center]] was another early open implementation. ANL has continued developing MPICH for over a decade, and now offers MPICH-4.3.20, implementing the MPI-34.1 standard.

* [[Open MPI]] (not to be confused with [[OpenMP]]) was formed by the merging FT-MPI, LA-MPI, [[LAM/MPI]], and PACX-MPI, and is found in many [[TOP-500]] [[supercomputer]]s.
