[slurm-users] Having Issue in Slurm cluster setup

[Ole Holm Nielsen]

Your slurm.conf line doesn't specify the node's physical memory:

NodeName=ozd2485u Gres=gpu:2 Sockets=2 CoresPerSocket=14 
ThreadsPerCore=2 State=UNKNOWN

See "man slurm.conf":

    RealMemory
               Size of real memory on the node in megabytes (e.g. 
"2048").  The default value is 1.
