[mpich-discuss] How can one test C\C++ code which uses MPI calls: is there any set of mock functions, that I can use?

[Jeff Hammond]

I recall that both LAMMPS and PETSc have a stub MPI implementation,
although I've only read the latter.  I doubt either is complete but
rather contains only a set of necessary MPI-1 routines.
