But the 'Low RealMemory' is incorrect. The entry in slurm.conf for
node012 is:
NodeName=node012 CPUs=4 Boards=1 SocketsPerBoard=2 CoresPerSocket=2
ThreadsPerCore=1 RealMemory=10193 State=UNKNOWN
Thanks for the info. Some questions arise:
1. Is slurmd running on the node?
2. What's the output of "slurmd -C" on the node?
3. Define State=UP in slurm.conf in stead of UNKNOWN
4. Why have you configured TmpDisk=0? It should be the size of the /tmp
filesystem.
Since you run Slurm 20.02, there are some suggestions in my Wiki page
https://wiki.fysik.dtu.dk/Niflheim_system/Slurm_configuration/#compute-node-configuration
where this might be useful:
Note for Slurm 20.02: The Boards=1 SocketsPerBoard=2 configuration gives error
messages, see bug_9241 and bug_9233. Use Sockets= in stead:
I hope changing these slurm.conf parameters will help.
Best regards,
Ole
