an error message and return 1.

Permit "SuspendTime=NONE" as slurm.conf value rather than only a numeric
value to match "scontrol show config" output. This remove some special
case logic in the test of "scontrol write config" and in the generation
of the output file written.

Double max string that Slurm can pack from 16MB to 32MB to support
larger MPI2 configurations.

Added SchedulerParameters option of "bf_busy_nodes". When selecting
resources for pending jobs to reserve for future execution (i.e. the job
can not be started immediately), then preferentially select nodes that are
in use. This will tend to leave currently idle resources available for
backfilling longer running jobs, but may result in allocations having less
than optimal network topology. This option is currently only supported by
the select/cons_res plugin.

This can happen if the specified job ID is not found.

Add advance reservation flag of "replace" that causes allocated resources
to be replaced with idle resources. This maintains a pool of available
resources that maintains a constant size (to the extent possible).

This plugin was never completed, so it is not worth the effort of
continued support at this time.

Added new job state of STOPPED indicating processes have been stopped with a
SIGSTOP (using scancel or sview), but retain its allocated CPUs. Job state
returns to RUNNING when SIGCONT is sent (also using scancel or sview).

This applies to salloc, sbatch, and srun.

Avoid including unused CPUs in a job's allocation when cores or sockets are
allocated. A minor variation of this has been tested with version 14.11, but
I do not want to risk introducing a problem with this new logic.

Do not requeue a batch job from slurmd daemon if it is killed while in
the process of being launched (a race condition introduced in v14.03.9).
