[mpich-discuss] Verify infiniband communication

[Chandler]

Hi all,
I configured and installed mpich-3.2.1 on our cluster with Mellanox 
infiniband adapters.  I used this command:

./configure --prefix=/opt/mpich-install --with-device=ch3:nemesis:mxm 
--with-mxm=/opt/hpcx-v2.0.0-gcc-inbox-redhat6.9-x86_64/mxm

which worked fine without errors, then "make install".  Now would like 
to verify that MPICH will use our infiniband network by default (the 
cluster also has 1Gbps ethernet network).  Can you let me know some test 
commands to run to verify the infiniband devices are used?

Thanks,
