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 is a library of routines that can be called from
Fortran and
C programs. MPI's advantage 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 optimised for the hardware it runs on).
