Can you compile Open MPI with the same compiler options?

I will have to try this latter, in theory if the library is compiled
with the options it will have the needed information.
ST (the makers of PGI) got back and I quote:
"You can try -Mipa=fast,inline,safe"
"I think for now, all libraries are safe. It is more a matter of how

Hi everyone,
Another little mystery for you all!
I have a relatively small MPI Fortran code which I can compile
successfully with Intel and PGI compiled OpenMPI 1.3.0 (and 1.2.5). No
problems with this.
On a separate machine I have a GNU Gfortran 4.3 OpenMPI 1.3.0
installation and I get
This error message is indicating that MPI_Comm_f2c is being invoked
before MPI_INIT.
Can you see if that is happening?
If it helps, you can run with the MCA parameter mpi_abort_print_stack
set to 1. This will print the stack when we abort. Or run with the
MCA parameter mpi_abort_delay se
For the app I am using, ORCA (a Quantum Chemistry program), when it was
compiled using openMPI 1.2.8 and run under 1.2.8 with the following in
the openmpi-mca-params.conf file:
btl=self,openib
the app ran fine with no traffic over my Ethernet network and all
traffic over my Infiniband network.

Sounds very strange, indeed. You might want to check that your app is
actually getting the MCA param that you think it is. Try adding:
-mca mpi_show_mca_params file,env
to your cmd line. This will cause rank=0 to output the MCA params it
thinks were set via the default files and/or environme
Thanks for the advice. Unfortunately the command line is internally
generated by the app and then invoked so I can't see it.
But, it doesn't matter anyway. It seems the Ethernet utilization
"problem" I thought I had does not exist.
So, I'm still looking for why my app using 1.2.8 is 50% faster
Is there an environment variable (or variables) I can set to do the
equivalent?
