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. Jeff On Thu, Jan 24, 2013 at 7:17 AM, Anton Daneyko <[email protected]> wrote:

Here's an example:

#include <mpi.h> double f() { double timer = MPI_Wtime(); return timer; }

What I am searching for is some set of mock MPI functions, so I can #include <mpi_mocks.h> instead of mpi.h and get it compiled without linking to MPI library. It could also be something like #define MOCK which will trigger this behavior in mpi.h. It feels, like I've stumbled on something like this, but I cannot find it right now.
