Thanks, I'll give it a try!

Probably the easiest solution is to tell OMPI not to use the second NIC. For
example, if that NIC is eth1, then you could do this:
mpirun -mca oob_tcp_if_exclude eth1 -mca btl_tcp_if_exclude eth1 ...
This tells both the MPI layer and the RTE to ignore the eth1 interface.

Thank you Jody and Ralph. Your suggestions got me up and running (well sort
of). I have run into another issue that I was wondering if you have had any
experience with. My server has one NIC that is static and a second that is
DHCP on a corp network (the only way to get to the outside world). M
See, it was a simple thing. Thank you for the information. I am trying it
now. Have to recompile and re-install openmpi for a heterogeneous network.
Now, knowing what to search for, I found that I can set the configuration of
the cluster in a file that mpirun and mpiexec can read.
mpirun --app
Also, did you remember to configure with --enable-heterogeneity?

Hi
I'm not sure i completely understood.
Is it the case that an application compiled on the dell will not work
on the PS3 and vice versa?
If this is the case, you could try this:
shell$ mpirun -np 1 --host a app_ps3 : -np 1 --host b app_dell
where app_ps3 is your application compiled on the PS3
