Is MPI Large or Small?


Up: Background Next: Where to use MPI? Previous: Features not in MPI


  • MPI is large (125 functions)
    -- MPI's extensive functionality requires many functions
    -- Number of functions not necessarily a measure of complexity

  • MPI is small (6 functions)
    -- Many parallel programs can be written with just 6 basic functions.

  • MPI is just right
    -- One can access flexibility when it is required.
    -- One need not master all parts of MPI to use it.
