Plese help [CPUs=24 Boards=1 SocketsPerBoard=1 CoresPerSocket=16 ThreadsPerCore=1]
I am installing slurm on a small cluster of 3 identical computers at the university. It turns out that I get the message when starting: error: NodeNames=hugo-big-1 CPUs=24 match no Sockets, Sockets*CoresPerSocket or Sockets*CoresPerSocket*ThreadsPerCore. Resetting CPUs. error: NodeNames=hugo-big-2 CPUs=24 match no Sockets, Sockets*CoresPerSocket or Sockets*CoresPerSocket*ThreadsPerCore. Resetting CPUs. error: NodeNames=hugo-big-3 CPUs=24 match no Sockets, Sockets*CoresPerSocket or Sockets*CoresPerSocket*ThreadsPerCore. Resetting CPUs. if I run sudo slurmd -C I get NodeName=hugo-big-1 CPUs=24 Boards=1 SocketsPerBoard=1 CoresPerSocket=16 ThreadsPerCore=1 RealMemory=128586 reading many post it seems there is a bug starting in version 18. However I had modify the slurm.conf file NodeName=hugo-big-1 CPUs=24 Boards=1 SocketsPerBoard=1 CoresPerSocket=16 ThreadsPerCore=1 RealMemory=128586 Gres=gpu:nvidia_geforce_rtx_3090:2 to several different version where I do not specify CPUs or sockets and I failed everytime. I do need help, any idea? warm regards Hugo Solis BTW. if I run lscpu I got that any product of Thread, cores or sockets do not result in 24.

Hi Hugo. i[3-9] have 2 kinds of cores: the more performant ones with hyperthreading and the slower ones without. From https://www.intel.com/content/www/us/en/products/docs/processors/core/core-1... : -8<-- These processors feature performance hybrid architecture1, combining two core microarchitectures on a single processor die. This architecture features Performance-cores, Efficient-cores and Intel® Thread Director2. With up to 24 cores (8 Performance-cores and 16 Efficient-cores) and up to 32 threads. -8<-- (similar to what's written in the page for 12th gen i9). How to handle these strange beasts in Slurm is another issue and I have no idea... We're only using Xeons (and AMDs) that have omogeneous cores.

dear people, Few days ago I wrote this email. Diego Zuccato kindly reply with an email that lead to the proper solution. I disabled hyperthreading in the bios, the computers gave now 16 Cpus and Slurm is not complaining. Very nice now. Knowing the possible mistake I did a search with better results on google and I got this link https://utcc.utoronto.ca/~cks/space/blog/linux/IntelHyperthreadingSurprise It seems it explains details but I did not go thru it since I was able to keep moving on my work. cheers On 2/16/25 21:41, Hugo Solís wrote:
