I'm redeploying the servers right now. I'll test this ASAP. ``` $ /usr/lib64/mpi/gcc/openmpi2/bin/ompi_info | grep osc MCA osc: pt2pt (MCA v2.1.0, API v3.0.0, Component v2.1.2) MCA osc: rdma (MCA v2.1.0,...

Also: - the IMB-MPI1 bench works fine in this setup - Both IMB-MPI1 and IMB-EXT works fine with openmpi 1.10.7

Here's what I get ``` [rdma03:14356] mca: base: components_register: registering framework osc components [rdma03:14356] mca: base: components_register: found loaded component pt2pt [rdma03:14356] mca: base: components_register: component pt2pt register function successful...

Doing this gets it working: ``` mpirun --host 192.168.0.1,192.168.0.2 -np 2 --allow-run-as-root --mca btl openib --mca osc ^rdma /usr/lib64/mpi/gcc/openmpi2/tests/IMB/IMB-EXT ```

You're right, the osc/rdma is not available in 1.10.7 (at least in our build) Using openmpi 1.10.7 ``` rdma03:~/:[0]# mpirun --mca osc_base_verbose 10 --host 192.168.0.1,192.168.0.2 -np 2 --allow-run-as-root /usr/lib64/mpi/gcc/openmpi/tests/IMB/IMB-EXT [rdma04:14655]...

I have an openmpi 3.0.0 package available that I can test quickly if that's of any interest. Anything else will need some more time

@ggouaillardet openmpi 3.0.0 behaves exactly like 2.1.3 and stalls
