We are pleased to announce the availability of Slurm release 22.05.0.
To highlight some new features in 22.05:
- Support for dynamic node addition and removal
(https://slurm.schedmd.com/dynamic_nodes.html)
- Support for native Linux cgroup v2 operation
- Newly added plugins to support HPE Slingshot 11 networks
(switch/hpe_slingshot), and Intel Xe GPUs (gpu/oneapi)
- Added new acct_gather_interconnect/sysfs plugin to collect statistics
from arbitrary network interfaces.
- Expanded and synced set of environment variables available in the
Prolog/Epilog/PrologSlurmctld/EpilogSlurmctld scripts.
- New "--prefer" option to job submissions to allow for a "soft
constraint" request to influence node selection.
- Optional support for license planning in the backfill scheduler with
"bf_licenses" option in SchedulerParameters.
The main Slurm documentation site at https://slurm.schedmd.com/ has been
updated now as well.
Slurm can be downloaded from https://www.schedmd.com/downloads.php .

Thank you, Tim!
The cgroup/v2 support is exciting! Minor nitpick: I was reading up on the new `--prefer` option in the `sbatch` man page¹ and I noticed that it refers to `--constraints` (plural), but the option is actually `--constraint`.
Regards,
