With 1.10.3 we saw the following errors with mpirun: [font2.cora.nwra.com:13982] [[23220,1],10] selected pml cm, but peer [[23220,1],0] on font1 selected pml ob1 which crashed MPI_Init. We worked around this by passing "--mca pml ob1". I notice now with openmpi 2.0.2 without that option I no longer see errors, but the mpi program will hang shortly after startup. Re-adding the option makes it work, so I'm assuming the underlying problem is still the same, but openmpi appears to have stopped alerting me to the issue.
