Compiling Explicitly

If you choose not to use the OpenMPI compilation scripts (mpicc/mpiCC/mpif77/mpif90) then you will have to compile and link your MPI program explicitly, specifying all of your include and library paths (and libraries) yourself.

If you need to find PGI-specific include files, they should be located in /home/software/rhel4/pgi/linux86/pgi-version.

We strongly recommend compiling using the OpenMPI versions we have created.
