I am trying to use Jumbo frames but mpirun will not start the job.
I am using OpenMPI v1.1 shipped with the latest Rocks (4.2).
Ifconfig is reporting that all the NIC on the cluster are using an MTU
of 9000 and the switch (HP Procurve) should be able to use Jumbo

Is there any special flag I need to pass to mpirun or a configuration
file I need to edit?
