See the description of cm vs. ob1 in the OMPI README. Here's the latest

The selection of cm is not wrong per se. You will find that the psm mtl is much

Hello,
I am using the latest trunk version of OMPI, in order to take advantage of the
new CUDA RDMA features (smcuda BTL). RDMA support is superb, however, I have to
give a manual parameter
mpirun --mca pml ob1 ...
to have the OB1 upper layer selected and, consequently, to get smcuda
