Thank you Ralph. I was able to ssh back and forth between nodes. It also
seemed that the environment variables were all set fine. Turning the
firewall down seems to make this work just fine.

Hi Yevgeny,
Thanks.
Here is the output of /usr/bin/ibv_devinfo:
hca_id: mlx4_0
transport: InfiniBand (0)
fw_ver: 2.8.000
node_guid: 0002:c903:0010:a85a
sys_image_gui
I have discovered slightly more information:When I replace node 'B' from the
new cluster with node 'C' from the old clusterI get the similar behavior but
with an error message:mpirun -H A,A,A,A,A,A,A ring (works from either node)
mpirun -H C,C,C ring (works from either node)
mpirun -H A
There are no firewalls by default. I can ssh between both nodes without a
password so I assumed that all is good with the comms.I can also get both nodes
to participate in the ring program at the same time.Its just that I am limited
to inly 2 processes if they are split between the nodes
ie:mpi
I'm going to move this over to the devel list...

Have you disabled firewalls between your compute nodes?

This appears to be similar to the problem described in:
https://svn.open-mpi.org/trac/ompi/ticket/2043
However, those fixes do not work for me.
I am running on an - i5 sandy bridge under Ubuntu 10.10 8 G RAM

Hi Jeff,
I am willing to help test OpenMPI with the NAG compiler from time to time but
not sure how. If you could give me specific instructions I am very happy to
help.
As for this technical issue, I did some research online. It appears that a
later version of Libtool (probably 2.2.10+) added
