Q. Explain the Message Passing Interface?
The Message Passing Interface (MPI) is a universal benchmark for providing communication among multiple simultaneous processes on a distributed memory system. Most of the popular parallel computing platforms provide at least one implementation of MPI. It was developed by the MPI forum comprising various experts from industry and academics. MPI has been applied as the library of routines which can be known as from languages such as FORTRAN, C, C++ and Ada programs. MPI was created in two phases MPI-1 and MPI-2.
