MPICH-1.2 (Message Passing Interface)
The MPI library is a standard message passing library for parallel applications. MPI supports parallel programming across a network of computer systems through a technique known as message passing. MPI establishes a practical, portable, efficient, and flexible standard for message passing that makes use of the most attractive features of a number of existing message passing systems, rather than selecting one of them and adopting it as the standard.
