The Message Passing Interface (MPI) is, strictly speaking, a standard describing a set of subroutines, functions, objects, etc., with which one can write parallel programs in a distributed memory environment. Many different implementations of the standard have been produced, such as Open MPI, Intel MPI, MPICH, and MVAPICH. The standard describes how MPI should be called from Fortran, C, and C++ languages, but unofficial "bindings" can be found for several other languages. Note that MPI 3.0 dropped official C++ bindings but instead you can use the C bindings from C++, or Boost MPI. For Python we give examples using the MPI for Python package mpi4py.
