Hi Artem, Granted I have never used SLURM on a large NUMA system but I would think that having one node is fine as long as SLURM properly recognizes your socket and core count. If you want to allocate sockets not cores then I would suggest using the consumable resources select plugin with either CR_Socket or CR_Socket_Memory for the value of SelectTypeParameter. Hopefully some other folks will chime in :)
