Hello,

I have compiled SLURM-24.11.3 and I have configured two GPUs in my system (slurmctld and slurmd are running in the same computer). Computes has a old processor Intel i7 with 4 cores and 4 hyperthreading. Node is configured with “NodeName=mysystem CPUs=8 Boards=1 SocketsPerBoard=1 CoresPerSocket=4 ThreadsPerCore=2 RealMemory=7940 Gres=gpu:geforce_gtx_titan_x:1,gpu:geforce_gtx_titan_black:1”. “lscpu” command returns:

Architecture:        x86_64

CPU op-mode(s):      32-bit, 64-bit

Byte Order:          Little Endian

CPU(s):              8

On-line CPU(s) list: 0-7

Thread(s) per core:  2

Core(s) per socket:  4

Socket(s):           1

NUMA node(s):        1

BIOS Vendor ID:      Intel(R) Corporation

Model name:          Intel(R) Core(TM) i7 CPU         950  @ 3.07GHz

BIOS Model name:     Intel(R) Core(TM) i7 CPU         950  @ 3.07GHz

File gres.conf is:

NodeName=mysystem Autodetect=off Name=gpu Type=geforce_gtx_titan_x File=/dev/nvidia0 CPUs=0-1

NodeName=mysystem Autodetect=off Name=gpu Type=geforce_gtx_titan_black File=/dev/nvidia1 CPUs=2-3

However, when I start daemon “slurmctld”, system returns this error:

[2025-04-28T09:35:41.003] error: _check_core_range_matches_sock: gres/gpu GRES core specification 0-1 for node aopcvis5 doesn't match socket boundaries. (Socket 0 is cores 0-3)

[2025-04-28T09:35:41.003] error: Setting node aopcvis5 state to INVAL with reason:gres/gpu GRES core specification 0-1 for node aopcvis5 doesn't match socket boundaries. (Socket 0 is cores 0-3)

Where is my configuration error?

Thanks.
