+[[!meta  title="Message passing interface"]]
+
+The [MPI][] framework allows separate processes in a parallel program
+to communicate.  The [standards][] are maintained by the [MPI
+Forum][].  There are several implementations, and the main ones are
+[MPICH2][] and [Open MPI][].  I've used both and they are fairly
+interchangeable.
+
+There are also several [[Python]] bindings for MPI, but the most
+popular seems to be [mpi4py][].
