[mpich-discuss] MPI Conditional Compile

[Anthony Chan]

There are couple ways of doing what you want.  You could add macros
to your fortran MPI program around all MPI calls, and enable those
calls conditionally through preprocessor (I think intel compiler supports
this, if not, you can always use GNU's cpp).  The 2nd way is that you can
gather all MPI calls used in your code and implement a null MPI library
when MPI isn't available.
