Sorry -- I missed many of these mails today due to mail filtering (don't ask).
FWIW:
- I'm not opposed to adding LOOPBACK checks into OMPI to avoid this problem
(I'm waiting for a patch, actually). I'm just saying that we're not going to
get a release out immediately with this fix. Our next

It does appear to work on OFED 1.4 and on 2.6.26 based on ucmatose. Is the
problem really with rdma_bind_addr succeeding, or with
On my OFED 1.4.1 RHEL4u6 systems, rdma_bind_addr() fails when attempting to

This is what I see over IB on 2.6.26, with a couple extra prints added to
cmatose:
Sean, can you try openmpi? It fails for me, and yet ucmatose succeeds.
I don't understand the difference yet...

I believe the issue is that rdma_bind_addr succeeds (returns 0), but no device
is assigned to the rdma_cm_id (verbs field is NULL).
This was a change from commit

Ah, yes! Per the OMPI code you cited, I amended my printf's and see:
