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

[Stuart MacLachlan]

Hi Steffan,

Not sure if the output from 'numactl --hardware' is more consistent and easier to parse with a script or similar?

Kind Regards,
Stuart

Hello,

I'm wondering whether there is some rule-of-thumb to translate the core config listed in https://urldefense.proofpoint.com/v2/url?u=https-3A__en.wikipedia.org_wiki_Epyc&d=DwIDAw&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=WRHOCjWNhD-hk2AQTjbVUqX9gELcVS7wxFXQqbJ02hk&m=tinTJJMaVo42Y9_sd_6GFqebHHPSHkAU7HWSxq9pJJk&s=4qtrnAVSz-nrQqws1E9H4JixtZQpj0dg3dtPszJpW1g&e= 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?

Thanks,
 Steffen
