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.
