Also set "JobAcctGatherType=jobacct_gather/linux" +for enforcement (periodic sampling of memory use by the job). + +Configure "TaskPlugin=task/affinity" and remove the "auto-affinity.so" +SPANK plugin with equivalent functionality. + +Remove the "preserve-env.so" SPANK plugin. The functionality is now +directly in SLURM. + +SLURM version 2.0 must use a database daemon (slurmdbd) at version 2.0 +or higher. While we are testing version 2.0, set "AccountingStoragePort=????". +Once we upgrade the production slurmdbd to version 2.0, this change will +not be required. + +SLURM state files in version 2.0 are different from those of version 1.3. +After installing SLURM version 2.0, plan to restart without preserving +jobs or other state information. While SLURM version 1.3 is still running, +cancel all pending and running jobs (e.g. +"scancel --state=pending; scancel --state=running"). Then stop and restart +daemons with the "-c" option or use "/etc/init.d/slurm startclean". -- GitLab
