[slurm-announce] Slurm version 21.08.3 is now available

[Tim Wickberg]

We are pleased to announce the availability of Slurm version 21.08.3.

This includes a number of fixes since the last release a month ago, 
including one critical fix to prevent a communication issue between 
slurmctld and slurmdbd for sites that have started using the new 
AccountingStoreFlags=job_script functionality.

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

>  -- Bring slurm_completion.sh up to date with changes to commands.

>     array per scheduling cycle instead of bb_array_stage_cnt jobs per scheduling
>     cycle.
>  -- Fix checking if the dependency is the same job for array jobs.
>  -- Fix checking for circular dependencies with job arrays.
>  -- Restore dependent job pointers on slurmctld startup to avoid race.

>  -- Correctly handle requested GRES when used in job arrays.
>  -- Fix error in pmix logic dealing with the incorrect size of buffer.
>  -- Fix handling of no_consume GRES, add it to allocated job allocated TRES.
>  -- Fix issue with typed GRES without Files= (bitmap).
>  -- Fix job_submit/lua support for 'gres' which is now stored as a 'tres'
>     when requesting jobs so needs a 'gres' prefix.
>  -- Fix regression where MPS would not deallocate from the node properly.
>  -- Fix --gpu-bind=verbose to work correctly.
>  -- Do not deny --constraint with special operators "[]()|*" when no changeable
>     features are requested, but continue to deny --constraint with special
>     operators when changeable features are requested.

>  -- openapi/v0.0.37 - request node states query includes MIXED state instead of
>     only allocated.
>  -- mpi/pmix - avoid job hanging until the time limit on PMIx agent failures.
>  -- Correct inverted logic where reduced version matching applied to non-SPANK
>     plugins where it should have only applied to SPANK plugins.

>  -- Limit max_script_size to 512 MB.
>  -- Fix shutdown of slurmdbd plugin to correctly notice when the agent thread
>     finishes.
>  -- slurmdbd - fix issue with larger batch script files being sent to SlurmDBD
>     with AccountingStoreFlags=job_script that can lead to accounting data loss
>     as the resulting RPC generated can exceed internal limits and won't be
>     sent, preventing further communication with SlurmDBD.
>     This issue is indicated by "error: Invalid msg_size" in your log files.
>  -- Fix compile issue with --without-shared-libslurm.
