- Update to 23.11.1 with following major improvements and fixing
CVE-2023-49933, CVE-2023-49934, CVE-2023-49935, CVE-2023-49936
and CVE-2023-49937
* Substantially overhauled the SlurmDBD association management
code. For clusters updated to 23.11, account and user
additions or removals are significantly faster than in prior
releases.
* Overhauled `scontrol reconfigure` to prevent configuration
mistakes from disabling slurmctld and slurmd. Instead, an
error will be returned, and the running configuration will
persist. This does require updates to the systemd service
files to use the `--systemd` option to `slurmctld` and `slurmd`.
* Added a new internal `auth/cred` plugin - `auth/slurm`. This
builds off the prior `auth/jwt` model, and permits operation
of the `slurmdbd` and `slurmctld` without access to full
directory information with a suitable configuration.
* Added a new `--external-launcher` option to `srun`, which is
automatically set by common MPI launcher implementations and
ensures processes using those non-srun launchers have full
access to all resources allocated on each node.
* Reworked the dynamic/cloud modes of operation to allow for
"fanout" - where Slurm communication can be automatically
offloaded to compute nodes for increased cluster scalability.
* Overhauled and extended the Reservation subsystem to allow
for most of the same resource requirements as are placed on
the job. Notably, this permits reservations to now reserve
GRES directly.
- Details of changes:
* Fix `scontrol update job=... TimeLimit+=/-=` when used with a
raw JobId of job array element.
