Hi, You can run /opt/mpich-install/examples/cpi to test the basic functionality of MPICH/mxm. For example: mpiexec -np 2 -ppn 1 -f <hostfile> ./cpi For more testing options, you can find information at http://www.mpich.org/documentation/guides/ Thanks, Min On 2018/01/23 19:09, Chandler wrote:
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,
