I'm getting poor performance on OpenMPI tasks on a new AMD 7401P EPYC
server. I suspect hwloc providing a poor topology may have something to do
with it as I receive this warning below when creating a job.
Requested data files available at http://static.skysight.io/out.tgz
Cheers,
Matthew

* The following FAQ entry in the hwloc documentation may help:
* What should I do when hwloc reports "operating system" warnings?
* Otherwise please report this error message to the hwloc user's mailing
list,
