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
Hi,
is it possible to have NFS and openmpi running on different NICs? By the way,
is it possible to have openmpi using multiple NICs without hardware support for
bonding?
Thank you in advance.

Hi,
no, I never tried Open MPI's checkpointing. But there are two Howto's
from which you may get some ideas to integrate it with SGE:

I have already been using the processor and memory affinity options to
bind the processes to specific cores. Does the presence of the
irqbalance daemon matter? I saw some recommendation to disable this
for a performance boost. Or is this irrelevant?

There are some proposals for Non-blocking collectives before the MPI

Let's start with this: You generate non-blocking sends (MPI_Isend).
Those sends are not completed anywhere. So, strictly speaking, they
don't need to be executed. In practice, even if they are executed, they
should be "completed" from the user program's point of view (MPI_Test,

Hi Reuti,
Yes, I sent a job with SGE and I checkpointed the mpirun process, by
hand, entering into the mpi master node. Then I killed the job with qdel
and after that I did the ompi-restart.
I will try to integrate with SGE creating a ckpt environment but I think
that it could be a bit difficu

do a successful restart... Maybe there was something wrong in the
