[slurm-users] Node specs for Epyc 7xx3 processors?

I'm wondering whether there is some rule-of-thumb to translate the core
config listed in https://en.wikipedia.org/wiki/Epyc to the node information
Slurm expects in "Sockets=x CoresPerSocket=y"? ("ThreadsPerCore=2" is clear.)

We'll be getting Epyc 7313 and 7513 machines, and perhaps add a single 7713
one - "lscpu" outputs are wildly different, while the total number of cores
is correct.

Will I have to wait until the machines have arrived, and do some experiments,
or did someone already retrieve the right numbers, and is willing to share?
