ourcluster->category[gpucategory]->roles]% use slurmclient [ourcluster->category[gpucategory]->roles[slurmclient]]% show ... RealMemory 196489092 ... [ ciscluster->category[gpucategory]->roles[slurmclient]]% Values are specified in MB and this line is saying that our node has 196TB of RAM. I set this using cmsh: # cmsh % category % use gpucategory % roles % use slurmclient % set realmemory 191846 % commit The value in /etc/slurm/slurm.conf was conflicting with this especially when restarting slurmctld.
