Foil 4 MPI Overview -- Comparison with HPF -- II

From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox
HPF runs on SIMD and MIMD machines and is high level as it expresses a style of programming or problem architecture
MPI runs on MIMD machines (in principle it could run on SIMD but unnatural and inefficient) -- it expresses a machine architecture
Traditional Software Model is
  • Problem --> High Level Language --> Assembly Language --> Machine
  • -------- Expresses Problem -- Expresses Machine
So in this analogy MPI is universal "machine-language" of Parallel processing
