[David M. Race]

I ran with the following configurations:

mpiexec.hydra -machinefile ./hostfile -np 64 ./mpibench FAILED
mpiexec.hydra -machinefile ./hostfile -np 64 -genv MV2_IBA_HCA mlx4_1 
-genv MV2_NUM_HCAS 1 ./mpibench         PASSED
mpiexec.hydra -machinefile ./hostfile -np 64 -genv MV2_IBA_HCA mlx4_0 
-genv MV2_NUM_HCAS 1 ./mpibench         PASSED
