Don't use the mpif.h from that site; Open MPI ships with its own.
mpif90 will find it -- you don't need to copy it into the same
directory as your .f sources.

Thanks for your reply Eugene.
Here is the result of the mpif90 -showme
/state/partition1/apps/intel/fce/10.1.015/bin/ifort -I/share/apps/
openmpi-1.2.6-intel/include -pthread -I/share/apps/openmpi-1.2.6-

The mpif.h file I got off the site. I used the Google "site:
mcs.anl.gov mpif.h" search and placed it into the same directory as
the main program.
So if it is the correct one, I am not sure.

I and new to OpenMPI and have looked for this, but not getting
anywhere.
I got an example program off this site:
The compute PI in Fortran example.
http://www.mcs.anl.gov/research/projects/mpi/usingmpi/examples/simplempi/main.htm
Compiled it with "mpif90" and no errors.
Then used the qsub -I and tried both executing directly and "mpirun"
and still receive these errors:
[MGT-2-1:02994] *** An error occurred in MPI_Comm_rank
[MGT-2-1:02994] *** on communicator MPI_COMM_WORLD
[MGT-2-1:02994] *** MPI_ERR_COMM: invalid communicator
[MGT-2-1:02994] *** MPI_ERRORS_ARE_FATAL (goodbye)
Any guidance in the right direction would be appreciated.
First, the example works fine for me.
You seem to be bombing in MPI_Comm_rank and before it asks you for
any input. I guess it's having problems with the MPI_COMM_WORLD
communicator being passed to MPI_Comm_rank? Maybe it's having
problems finding the mpif.h include file? It's finding *some*
mpif.h include file, but presumably not the right one. Make sure
the mpif90 and mpirun commands are the ones you think you should be
getting and, if they are, try adding -showme to the mpif90 line to
see where it's looking for the mpif.h include file.
