Dear all, a small update.

So, maybe this wouldn't be a big disadvantage, if that allows us to use 32 slots on the "16 Cores with 2 SMT" Xeons in the PowerEdge R720 machines with Ubuntu 20.04Has anyone else encountered this problem? Is there a better/proper for using all SMT/HT cores?
It took about half an hour - with no jobs running, besides some test jobs - for the node to fall into "drained" state again:

Thus,NodeName=ekgen[8] RealMemory=250000 Sockets=2 CoresPerSocket=16 ThreadsPerCore=1 State=UNKNOWN
isn't a working node declaration either.The question remains why a declaration matching the output of slurmd -C doesn't work with Ubuntu-20.04
