Hello, Yes, I know system is single-socket, but in a similar computer, this configuration works fine... After some tests, I have realized that with SLURM 23.11.0 I can assign CPUs in "gres.conf" (and, then, use half CPU for one GPU and other half for other GPU), but with SLURM 24.11.4 I receive " _check_core_range_matches_sock". I have read "NEWS" file inside sources files in 24.11.4 tgz and it says: […] * Changes in Slurm 23.11.7 ========================== […] -- Fix issue that only left one thread on each core available when "CPUs=" is configured to total thread count on multi-threaded hardware and no other topology info ("Sockets=", "CoresPerSocket", etc.) is configured. […] So, I suppose, in version 23.11.7 SLURM corrected that behaviour. Could someone confirm that? Thanks.
