Open MPI and MPICH are both implementations of the MPI standard. As
such, correct MPI applications should be completely source-portable
between Open MPI and any other MPI implementation (including MPICH).

Hello,
I want to know if I need to make any modifications to my source code
to replace MPICH-1.2.6 with Openmpi-1.2.7?? I mean are the function
interfaces exactly the same in both MPISH and OMPI?? please let me
know.
Thanks.
