We are pleased to announce the availability of Slurm version 21.08.6.
This includes a number of fixes since the last maintenance release was
made in December, including an import fix to a regression seen when
using the 'mpirun' command within a job script.
Slurm can be downloaded from https://www.schedmd.com/downloads.php .

* Changes in Slurm 21.08.6
==========================
-- Handle typed shared GRES better in accounting.
-- Fix plugin_name definitions in a number of plugins to improve logging.
-- Close sbcast file transfers when job is cancelled.
-- job_submit/lua - allow mail_type and mail_user fields to be modified.
-- scrontab - fix handling of --gpus and --ntasks-per-gpu options.
-- sched/backfill - fix job_queue_rec_t memory leak.
-- Fix magnetic reservation logic in both main and backfill schedulers.
-- job_container/tmpfs - fix memory leak when using InitScript.
-- slurmrestd / openapi - fix memory leaks.
-- Fix slurmctld segfault due to job array resv_list double free.
-- Fix multi-reservation job testing logic.
-- Fix slurmctld segfault due to insufficient job reservation parse validation.
-- Fix main and backfill schedulers handling for already rejected job array.
-- sched/backfill - restore resv_ptr after yielding locks.
-- acct_gather_energy/xcc - appropriately close and destroy the IPMI context.
-- Protect slurmstepd from making multiple calls to the cleanup logic.
-- Prevent slurmstepd segfault at cleanup time in mpi_fini().
-- Fix slurmctld sometimes hanging if shutdown while PrologSlurmctld or
EpilogSlurmctld were running and PrologEpilogTimeout is set in slurm.conf.
-- Fix affinity of the batch step if batch host is different than the first
node in the allocation.
-- slurmdbd - fix segfault after multiple failover/failback operations.
-- Fix jobcomp filetxt job selection condition.
-- Fix -f flag of sacct not being used.
-- Select cores for job steps according to the socket distribution. Previously,
sockets were always filled before selecting cores from the next socket.
-- Keep node in Future state if epilog completes while in Future state.
-- Fix erroneous --constraint behavior by preventing multiple sets of brackets.
-- Make ResetAccrueTime update the job's accrue_time to now.
-- Fix sattach initialization with configless mode.
-- Revert packing limit checks affecting pmi2.
-- sacct - fixed assertion failure when using -c option and a federation
display
-- Fix issue that allowed steps to overallocate the job's memory.
-- Fix the sanity check mode of AutoDetect so that it actually works.
-- Fix deallocated nodes that didn't actually launch a job from waiting for
Epilogslurmctld to complete before clearing completing node's state.
-- Job should be in a completing state if EpilogSlurmctld when being requeued.
-- Fix job not being requeued properly if all node epilog's completed before
EpilogSlurmctld finished.
-- Keep job completing until EpilogSlurmctld is completed even when "downing"
a node.
-- Fix handling reboot with multiple job features.
-- Fix nodes getting powered down when creating new partitions.
-- Fix bad bit_realloc which potentially could lead to bad memory access.
-- slurmctld - remove limit on the number of open files.
-- Fix bug where job_state file of size above 2GB wasn't saved without any
error message.
-- Fix various issues with no_consume gres.
-- Fix regression in 21.08.0rc1 where job steps failed to launch on systems
that reserved a CPU in a cgroup outside of Slurm (for example, on systems
with WekaIO).
-- Fix OverTimeLimit not being reset on scontrol reconfigure when it is
removed from slurm.conf.
-- serializer/yaml - use dynamic buffer to allow creation of YAML outputs
larger than 1MiB.
-- Fix minor memory leak affecting openapi users at process termination.
-- Fix batch jobs not resolving the username when nss_slurm is enabled.
-- slurmrestd - Avoid slurmrestd ignoring invalid HTTP method if the response
serialized without error.
-- openapi/dbv0.0.37 - Correct conditional that caused the diag output to
give an internal server error status on success.
-- Make --mem-bind=sort work with task_affinity
-- Fix sacctmgr to set MaxJobsAccruePer{User|Account} and MinPrioThres in
sacctmgr add qos, modify already worked correctly.
-- job_container/tmpfs - avoid printing extraneous error messages in Prolog
and Epilog, and when the job completes.
-- Fix step CPU memory allocation with --threads-per-core without --exact.
-- Remove implicit --exact when --threads-per-core or --hint=nomultithread
is used.
-- Do not allow a step to request more threads per core than the
allocation did.
-- Remove implicit --exact when --cpus-per-task is used.
