[mpich-discuss] help with hybrid programming of OPenMP and MPI

[Jeff Hammond]

Read the Intel Fortran compiler manual for Windows to see what the
appropriate flag to use to enable OpenMP is.  This is not in any way
related to MPICH2, by the way.

You will get the appropriate MPI options by using the MPI wrapper
scripts once you've build MPICH2 appropriately using the Intel
compilers.

You should be able to extend the canonical cpi test to use OpenMP
rather trivially (especially since you work at a software company) to
verify that your build is correct.
