Create a Slurm topology.conf file to get the correct node and switch Infiniband connectivity.
The OFED command ibnetdiscover.
On EL8/9 Linux this is part of the infiniband-diags RPM package.
Usage: slurmibtopology.sh [-c]
where:
-c: comments in the output will be filtered
-V: Version information
-h: Print this help information
The comments are useful to understand the output of ibnetdiscover,
but you may want to filter them using -c.
