Message Passing Interface (MPI)

The Message Passing Interface (MPI) is a computer communications protocol. It is a de facto standard for communication among the nodes running a parallel program on a distributed memory system. MPI implementations consist of a library of routines that can be called from Fortran, C, C++ and Ada programs. The advantage of MPI over older message passing libraries is that it is both portable (because MPI has been implemented for almost every distributed memory architecture) and fast (because each implementation is optimized for the hardware on which it runs). Often compared with PVM and at one stage merged with PVM to form PVMMPI.
