Hi,
can you please run again with
--mca pml ob1
if Open MPI was built with mxm support, pml/cm and mtl/mxm are used

Cheers,

Hi folks,
I saw a performance degradation of openmpi-2.0.0 when I ran our application
on a node (12cores). So I did 4 tests using osu_bw as below:
1: mpirun –np 2 osu_bw bad(30% of test2)
2: mpirun –np 2 –mca btl self,sm osu_bw good(same as openmpi1.10.3)
