iWARP _requires_ the RDMA-CM for connection setup...

So OMPI as it stands today won't work over iwarp devices.

Right now, the only non-uDAPL MPI solution that will work with the iwarp
stable svn branch + 2.6.17 RNFS is MVAPICH2.

If you utilize uDAPL, then Intel and HP have MPI libs that might work...
