At the risk of hyperbole, there was probably no greater achievement of practical utility for the advancement of high performance computing (HPC) than the development of MPI. While the application programming interface itself contains hundreds of commands, the HPC practitioner generally only needs a small subset of these to create a wide array of parallel applications.
