Message Passing Interface
The Message Passing Interface
(MPI) is a computer
. It is a de facto standard
among the nodes running a parallel program on a distributed memory system. MPI is a library of routines that can be called from Fortran
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).
The most common implementation in use is MPICH.
