MPI_STUBS
Dummy MPI Library


MPI_STUBS is a FORTRAN90 library which provides "stub" versions of some MPI routines.

MPI_STUBS is intended to include stubs for the most commonly called MPI routines. Most of the stub routines don't do anything. In a few cases, where it makes sense, they do some simple action or return a value that is appropriate for the serial processing case.

MPI_STUBS can be used as a convenience, when a real MPI implementation is not available, and the user simply wants to test-compile a code. It may also be useful in those occasions when a code has been so carefully written that it will still execute correctly on a single processor.

MPI_STUBS is based on a similar package supplied as part of the LAMMPS program, which allow that program to be compiled, linked and run on a single processor machine, although it is normally intended for parallel execution.
