Hello!

after migrating a infiniband cluster to SL6.1 we noticed
that the MPI jobs can't use openib anymore. So we checked
first with perftest but verbs is working. Even IPOIB
works. 

So we looked at the openmpi package, and observe that our 
self compiled openmpi  package is still working as expected.

So we would really prefer to go with the SL openmpi package,
has anybody experienced the same problems? Is there any known SL6.1
problem with openmpi??

Kernel: 2.6.32-220.2.1.el6.x86_64
openmpi-1.4.3-1.1.el6.x86_64


best regards!
