Hi: I recently tried to build my MPI application against OpenMPI 1.3.3. It worked fine with OMPI 1.2.9, but with OMPI 1.3.3, it hangs part way through. It does a fair amount of comm, but eventually it stops in a Send/Recv point-to-point exchange. If I turn off the openib btl, it runs to completion. Also, I built 1.3.3 with memchecker (which is very nice; thanks to everyone who worked on that!) and it runs to completion, even with openib active.
Our cluster consists of dual dual-core opteron boxes with Mellanox
MT25204 (InfiniHost III Lx) HCAs and a Mellanox MT47396 Infiniscale-III
switch. We're running RHEL 4.8 which appears to include OFED 1.4. I've
built everything using GCC 4.3.2. Here is the output from ibv_devinfo.
"ompi_info --all" is attached.

I'd appreciate any tips for debugging this.
Thanks,
