byBy seeing the systemctl configuration you've provided, I can tell this things:
1- As for slurmdslurmd, the HW configuration you defined in slurm.conf is not correct. What are the HW specifications of the node this configuration will run on?
(Mar 05 05:57:17 thoma-Lenovo-Legion-5-15IMH05H slurmd[6514]: slurmd: error: Node configuration differs from hardware: CPUs=12:12(hw) Boards=1:1(hw) SocketsPerBoard=12:1(hw) CoresPerSocket=1:6(hw) ThreadsPerCore>)
According to this output, your values for SocketsPerBoardSocketsPerBoard and CoresPerSocketCoresPerSocket, should be 11 and 66 respectively.
2- Regarding slurmctldslurmctld, the initial node status should be UNKNOWNUNKNOWN, like this.
NodeName=localhost CPUs=12 RealMemory=30517 State=UNKNOWN PartitionName=localhost Nodes=ALL Default=YES MaxTime=INFINITE State=UP
NOTE: I have seen you have put "8000""8000" as your RealMemoryRealMemory value. Try using the value "8192""8192" instead, as Slurm uses MiB values :)
Try changing these, then restartrestart both slurmdslurmd and slurmctldslurmctld and let me know if that helps.
Cheers!
