HPF runs on SIMD and MIMD machines and is high level as it expresses a style of programming or problem architecture
|
2 |
MPI runs on MIMD machines (in principle it could run on SIMD but unnatural and inefficient) -- it expresses a machine architecture
|
3 |
Traditional Software Model is
-
Problem --> High Level Language --> Assembly Language --> Machine
-
Expresses Problem Expresses Machine
|
4 |
So in this analogy MPI is universal "machine-language" of Parallel processing
|
5 |
MPI can be built efficiently at low risk whereas HPF compiler is difficult project with many unsolved issues
