[Beowulf] How to debug error with Open MPI 3 / Mellanox / Red Hat?

I agree with Gus that you should be asking this question on the OpenMPI 
mailing list where there's more expertise specific to OpenMPI.  Based on 
your error message

> mca_base_component_repository_open: unable to open
> mca_btl_usnic: libpsm_infinipath.so.1: cannot open shared object file:
> No such file or directory (ignored)

It looks like it's not a problem with IB libraries in general, but that 
you are missing the PSM libraries. PSM is an additional library used by 
QLogic cards, so installing Mellanox OFED will not help you out here. In 
fact, it will probably just make things worse. Since Intel bought QLogic 
a while back, I think you need to install the Intel PSM RPMs.

If you are not using QLogic cards in your cluster, you will need to 
rebuild OpenMPI without PSM support.

Did you build this software on one system and install it on a shared 
filesystem, or copy it to the other nodes after the build? If so, the 
build system probably has the proper libraries installed. The 
configuration command-line for this build doesn't explicitly mention PSM:

When something is included that isn't explicitly stated on the 
configuration line, that usually means the configure script looked for 
the supporting libraries, found them, and so decided to include the 
support for that feature.
