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

[Anton Daneyko]

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.
