Hi Gerry
You may need to compile a hybrid OpenMPI
using gcc for C, PGI f90 for Fortran on the OpenMPI configure script.
This should give you the required mpicc and mpif90 to do the job.
I guess this is what Elvedin meant on his message.
I have these hybrids for OpenMPI and MPICH2 here
(not Myrinet but GigE), and they work
fine with a WRF relative (CAM3, atmospheric climate).
Two cents from

Elvedin,
Yeah, I thought about that after finding a reference to this in the
archives, so I redirected the path to MPI toward the gnu-compiled
version. It died in THIS manner:
make[3]: Entering directory `/home/gerry/WRFv3/WRFV3/external/RSL_LITE'
mpicc -cc=gcc -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -c c_code.c
pgcc-Error-Unknown switch: -cc=gcc
make[3]: [c_code.o] Error 1 (ignored)
Methinks the wrf configuration script and make file will need some tweeks.
Interesting thing: I have another system (alas, with mpich) where it
compiles just fine. I'm trying to sort this out, as on 2 systems, with
openMPI, it does odd dances before dying.
I'm still trying things. I've gotta get this up both for MY research
and to support other users.
Thanks, Gerry

WRF almost requires that you use gcc for the C/C++ part and the PGI
Fortran compilers, if you choose that option. I'd suggest compiling
OpenMPI in the same way as that has resolved our various issues. Have
you tried that with the same result?

Howdy,
I'm new to this list. I've done a little review but likely missed
something specific to what I'm asking. I'll keep looking but need to
resolve this soon.
I'm running a Rocks cluster (centos 5), with PGI 7.2-3 compilers,
Myricom MX2 hardware and drivers, and OpenMPI1.3
I installed the Myricom roll which has OpenMPI compiled with gcc. I
recently compiled the openmpi code w/ PGI.
I've the MPICH_F90 pointing to the right place, and we're looking for
the right includes and libs by means of LD_LIBRARY_PATH, etc.
When I tried to run, I got the following error:
make[3]: Entering directory `/home/gerry/WRFv3/WRFV3/external/RSL_LITE'

Note that I had modified the makefile to use PGI in place of gcc, and
thus, the PGI-compiled openMPI.
Thanks, Gerry
