The Message-Passing Interface (MPI) is a standard for expressing distributed parallelism via message passing. MPI consists of a header file, a library of routines and a runtime environment. When you compile a program that has MPI calls in it, your compiler links to a local implementation of MPI, and then you get parallelism; if the MPI library isn’t available, then the compile will fail. MPI can be used in Fortran, C and C++.Computer SciencePresentation
