Merits of MPI

  • Runs on any shared or distributed memory architectures;
  • Can be used on a wider range of troubles than OpenMP;
  • Every process has its own local variables; and
  • Distributed memory computers are not costly rather than large shared memory computers.

  • Needs more programming changes to go from serial to parallel version.
  • Can be harder to debug, and
  • Performance is partial by the communication network among the nodes.
