I am having issues building OpenMPI 4.0.2 using the PGI 19.10 compilers. OS is CentOS 7.7,
MLNX_OFED 4.7.3
It dies at:

AMD, list the minimum supported kernel for EPYC/NAPLES as RHEL/Centos
kernel 3.10-862, which is RHEL/CentOS 7.5 or later. Upgraded kernels can
be used in 7.4.

Is there a way to determine, at run time, as to what choices OpenMPI
made in terms of transports that are being utilized? We want to verify
we are running UCX over Infiniband.
I have two users, executing the identical code, with the same mpirun
options, getting vastly different execution time

As a test, I rebooted a set of nodes. The user could run on 480 cores,
on 5 nodes. We could not run beyond two nodes previous to that.
We still get the VM_UNMAP warning, however.

compilers. We could run with no issues.
