[slurm-users] Gres GPU Resource Issue

[Marcus Wagner]

Andrew,

you could try change it to the following:

/etc/slurm/slurm.conf:
NodeName=node[1-3]      CPUs=40 RealMemory=48000 Sockets=2 
CoresPerSocket=10 ThreadsPerCore=2 Feature="p4000" Gres=gpu:pascal:8 
State=UNKNOWN
NodeName=node[4-5,7-10] CPUs=8  RealMemory=48000 Sockets=2 
CoresPerSocket=4  ThreadsPerCore=1 Feature="p1000" Gres=gpu:pascal:4 
State=UNKNOWN
NodeName=node[6]        CPUs=24 RealMemory=30000 Sockets=2 
CoresPerSocket=6  ThreadsPerCore=2 Feature="p1000" Gres=gpu:pascal:4 
State=UNKNOWN

/etc/slurm/gres.conf
NodeName=node[1-3]  Name=gpu Type=pascal File=/dev/nvidia[0-7]
NodeName=node[4-10] Name=gpu Type=pascal File=/dev/nvidia[0-4]

Best
Marcus
