- Update to 20.11.03
- This release includes a major functional change to how job step launch is
handled compared to the previous 20.11 releases. This affects srun as
well as MPI stacks - such as Open MPI - which may use srun internally as
part of the process launch.
One of the changes made in the Slurm 20.11 release was to the semantics
for job steps launched through the 'srun' command. This also
inadvertently impacts many MPI releases that use srun underneath their
own mpiexec/mpirun command.
For 20.11.{0,1,2} releases, the default behavior for srun was changed
such that each step was allocated exactly what was requested by the
options given to srun, and did not have access to all resources assigned
to the job on the node by default. This change was equivalent to Slurm
setting the --exclusive option by default on all job steps. Job steps
desiring all resources on the node needed to explicitly request them
through the new '--whole' option.
In the 20.11.3 release, we have reverted to the 20.02 and older behavior
of assigning all resources on a node to the job step by default.
This reversion is a major behavioral change which we would not generally
do on a maintenance release, but is being done in the interest of
restoring compatibility with the large number of existing Open MPI (and
other MPI flavors) and job scripts that exist in production, and to
remove what has proven to be a significant hurdle in moving to the new
release.
Please note that one change to step launch remains - by default, in
20.11 steps are no longer permitted to overlap on the resources they
have been assigned. If that behavior is desired, all steps must
explicitly opt-in through the newly added '--overlap' option.

- Add support for configuration files from external plugins.
While built-in plugins have their configuration added in slurm.conf,
external SPANK plugins add their configuration to plugstack.conf
To allow packaging easily spank plugins, their configuration files
should be added independently at /etc/spack/plugstack.conf.d and
plugstack.conf should be left with an oneliner including all the
files under /etc/spack/plugstack.conf.d

- Update to version 20.11.0
Slurm 20.11 includes a number of new features including:
* Overhaul of the job step management and launch code, alongside improved
GPU task placement support.
* A new "Interactive Step" mode of operation for salloc.
* A new "scrontab" command that can be used to submit and manage
periodically repeating jobs.

Highlights:
* Exclusive behavior of a node includes all GRES on a node as well
as the cpus.
* Use python3 instead of python for internal build/test scripts.
The slurm.spec file has been updated to depend on python3 as well.
* Added new NodeSet configuration option to help simplify partition
configuration sections for heterogeneous / condo*style clusters.
* Added slurm.conf option MaxDBDMsgs to control how many messages will be
stored in the slurmctld before throwing them away when the slurmdbd is down.
* The checkpoint plugin interface and all associated API calls have been
removed.
* slurm_init_job_desc_msg() initializes mail_type as uint16_t. This allows
mail_type to be set to NONE with scontrol.
* Add new slurm_spank_log() function to print messages back to the user from
within a SPANK plugin without prepending "error: " from slurm_error().
* Enforce having partition name and nodelist=ALL when creating reservations
with flags=PART_NODES.
* SPANK - removed never-implemented slurm_spank_slurmd_init() interface. This
hook has always been accessible through slurm_spank_init() in the
S_CTX_SLURMD context instead.
* sbcast - add new BcastAddr option to NodeName lines to allow sbcast traffic
to flow over an alternate network path.
* Added auth/jwt plugin, and 'scontrol token' subcommand. PMIx - improve
* performance of proc map generation. Deprecate kill_invalid_depend in
* SchedulerParameters and move it to a new
option called DependencyParameters.
* Enable job dependencies for any job on any cluster in the same federation.
* Allow clusters to be added automatically to db at startup of ctld. Add
* AccountingStorageExternalHost slurm.conf parameter. The

- BuildRequire pkgconfig(systemd) instead of systemd: allow OBS to
shortcut through the -mini flavors.
- Use systemd_ordering instead of systemd_requires: systemd is
never a strict requirement; but in case the system is scheduled
for installation together with systemd, we want systemd to be
installed prior to slurm.
