Hi, I am setting up Slurm on our lab's 3 node cluster and I have run into a problem while adding GPUs (each node has an NVIDIA 4070 ti) as a GRES. There is an error at the 'debug' log level in slurmd.log that says that the GPU is file-less and is being removed from the final GRES list. This error according to some older posts on this forum might be fixed by reinstalling / reconfiguring Slurm with the right flag (the '--with-nvml' flag according to this <https://groups.google.com/g/slurm-users/c/cvGb4JnK8BY> post).
Line in /var/log/slurmd.log: [2024-04-03T15:42:02.695] debug: Removing file-less GPU gpu:rtx4070 from final GRES list Does this error require me to either reinstall / reconfigure Slurm? What does 'reconfigure Slurm' mean? I'm about as clueless as a caveman with a smartphone when it comes to Slurm administration and Linux system administration in general. So, if you could, please explain it to me as simply as possible. slurm.conf without comment lines: ClusterName=DlabCluster SlurmctldHost=server1 GresTypes=gpu ProctrackType=proctrack/linuxproc ReturnToService=1 SlurmctldPidFile=/var/run/slurmctld.pid SlurmctldPort=6817 SlurmdPidFile=/var/run/slurmd.pid SlurmdPort=6818 SlurmdSpoolDir=/var/spool/slurmd SlurmUser=root StateSaveLocation=/var/spool/slurmctld TaskPlugin=task/affinity,task/cgroup InactiveLimit=0 KillWait=30 MinJobAge=300 SlurmctldTimeout=120 SlurmdTimeout=300 Waittime=0 SchedulerType=sched/backfill SelectType=select/cons_tres JobCompType=jobcomp/none JobAcctGatherFrequency=30 SlurmctldDebug=debug2 SlurmctldLogFile=/var/log/slurmctld.log SlurmdDebug=debug2 SlurmdLogFile=/var/log/slurmd.log NodeName=server[1-3] RealMemory=128636 Sockets=1 CoresPerSocket=64 ThreadsPerCore=2 State=UNKNOWN Gres=gpu:rtx4070:1 PartitionName=mainPartition Nodes=ALL Default=YES MaxTime=INFINITE State=UP gres.conf (only one line): AutoDetect=nvml While installing cuda, I know that nvml has been installed because of this line in /var/log/cuda-installer.log: [INFO]: Installing: cuda-nvml-dev Thanks! PS: I could've added this as a continuation to this post <https://groups.google.com/g/slurm-users/c/p68dkeUoMmA>, but for some reason I do not have permission to post to that group, so here I am starting a new thread.
