We are pleased to announce the availability of Slurm version 23.11.6.

The 23.11.6 release includes two different problems with the priority/multifactor plugin: a crash and a miscalculation of AssocGrpCPURunMinutes after a slurmctld reconfiguration/restart. The wsrep_on errors that sites running MySQL or older MariaDB should happen much less frequently and has a clarifying statement when it is an innocuous error.

Slurm can be downloaded from https://www.schedmd.com/downloads.php .

• Changes in Slurm 23.11.6

========================== -- Avoid limiting sockets per node to one when using gres enforce-binding. -- slurmrestd - Avoid permission denied errors when attempting to listen on the same port multiple times. -- Fix GRES reservations where the GRES has no topology (no cores= in gres.conf). -- Ensure that thread_id_rpc is gone before priority_g_fini(). -- Fix scontrol reboot timeout removing drain state from nodes. -- squeue - Print header on empty reponse to `--only-job-state`. -- Fix slurmrestd not ending job properly when xauth is not present and a x11 job is sent. -- Add experimental job state caching with SchedulerParameters=enable_job_state_cache to speed up querying job states with squeue --only-job-state. -- slurmrestd - Correct dumping of invalid ArrayJobIds returned from 'GET /slurm/v0.0.40/jobs/state'. -- squeue - Correct dumping of invalid ArrayJobIds returned from `squeue --only-job-state --{json|yaml}`. -- If scancel --ctld is not used with --interactive, --sibling, or specific step ids, then this option issues a single request to the slurmctld to signal all jobs matching the specified filters. This greatly improves the performance of slurmctld and scancel. The updated --ctld option also fixes issues with the --partition or --reservation scancel options for jobs that requested multiple partitions or reservations. -- slurmrestd - Give EINVAL error when failing to parse signal name to numeric signal. -- slurmrestd - Allow ContentBody for all methods per RFC7230 even if ignored. -- slurmrestd - Add 'DELETE /slurm/v0.0.40/jobs' endpoint to allow bulk job signaling via slurmctld. -- Fix combination of --nodelist and --exclude not always respecting the excluded node list. -- Fix jobs incorrectly allocating nodes exclusively when started on a partition that doesn't enforce it. This could happen if a multi-partition job doesn't specify --exclusive and is evaluated first on a partition configured with OverSubscribe=EXCLUSIVE but ends up starting in a partition configured with OverSubscribe!=EXCLUSIVE evaluated afterwards. -- Setting GLOB_SILENCE flag no longer exposes old bugged behavior. -- Fix associations AssocGrpCPURunMinutes being incorrectly computed for running jobs after a controller reconfiguration/restart. -- Fix scheduling jobs that request --gpus and nodes have different node weights and different numbers of gpus. -- slurmrestd - Add "NO_CRON_JOBS" as possible flag value to the following: 'DELETE /slurm/v0.0.40/jobs' flags field. 'DELETE /slurm/v0.0.40/job/{job_id}?flags=' flags query parameter. -- Fix scontrol segfault/assert failure if the TRESPerNode parameter is used when creating reservations. -- Avoid checking for wsrep_on when restoring streaming replication settings. -- Clarify in the logs that error "1193 Unknown system variable 'wsrep_on'" is innocuous. -- accounting_storage/mysql - Fix problem when loading reservations from an archive dump. -- slurmdbd - Fix minor race condition when sending updates to a shutdown slurmctld. -- slurmctld - Fix invalid refusal of a reservation update. -- openapi - Fix memory leak of /meta/slurm/cluster response field. -- Fix memory leak when using auth/slurm and AuthInfo=use_client_ids.
