- You need a portable parallel program.
- You are writing a parallel library.
- You have irregular or dynamic data relationships that do not fit a data parallel model.
Where not to use MPI:
- You can use HPF or a parallel Fortran 90.
- You don't need parallelism at all.
- You can use libraries (which may be written in MPI).
