Hi Dmitry
Yes, we do it here.
Besides Bill's recommendations
you can also use different host/interface names
for, say, eth0 and eth1, in /etc/hosts.
Moreover, you should set OpenMPI to use only the specific
subnet/ports you want to dedicate to MPI, say, eth1.
See these faq:
http://www.open-mpi.org/faq/?category=tcp#tcp-selection
http://www.open-mpi.org/faq/?category=sysadmin#sysadmin-mca-params
Also, add "sm" to the -mca btl parameters.
My $0.02.

Hi,
is it possible to have NFS and openmpi running on different NICs?
Yes. Just make sure that the two subnets for the NICs don't overlap and
that your routing tables are correct.
As for channel bonding, I'll let someone who has actually used it
address that question. :-)
