MPI
MPI (Message Passing Interface) is a library, which is designed to provide the information exchange between different tasks of a distributed memory parallel program. It is presently the de-facto standard to implement message passing in programs written in Fortran, C or C++.
It consists of a group of functions which supports different communication operations.
