...and for the SchedMD folks, it would be a lot simpler to
drop/disambiguate the "year it was released" first element in the version
number, and just use it as an incrementing major version number.

Hi Pariksheet,
To confirm, "14", "15", "16", and "17" do not denote major versions. For
example, "17.02" and "17.11" are different major versions. Only "MM.NN"
denotes a major version. This is somewhat unintuitive, and I've suggested
some documentation clarification, but it's still somewhat easily
To emphasize what Thomas wrote: backfill will only be useful if users submit
jobs with realistic runtime limits. If every job is submitted with a default
runtime of, for example, 7 days, then Slurm will not backfill your small jobs

Yup - I checked for backfill yesterday. It's backfill.

I see. Thanks a lot for the in depth explanation.

"-uid" is a perfectly valid sbatch flag:
-u, --usage
Display brief help message and exit.
-i, --input=
Instruct Slurm to connect the batch script's standard input
directly to the file name specified in the
"filename pattern".
Slight correction, it does not look for a file named "d" in the home folder
of the user in the (mistyped) -uid parameter, it looks for a file named "d"
in the home folder of the user running sbatch. If this is not an expected
behaviour, I will make a complete bug report.

Thanks a lot for your answers again!
@Marcus Thanks a lot for the clarification.
About --uid, you are correct, I was mistyping it as -uid. But, the
behaviour is slightly inconsistent:
* If correctly typed (--uid) sbatch properly complains about needing to be
root
* If not present at all, or ignor

You can use squeue to see the priority of jobs. I believe it normally
shows jobs in order of priority, even though does not display priority. If
you want to see actual priority, you need to request it in the format
field. I typically use
squeue -o "%.18i %.12a %.6P %.8u %.2t %.8m %.4D %.4C %12l

a. You pretty much have to roll your own. We do it with our
serial_requeue partition which underlays all our hardware and is at the
lower priority.

not aware of what quirks there are. We use requeue. A caution I would

Hi mahmood,
yes that is totally normal.
please use sbatch instead of salloc.
If you use salloc, you just create an allocation. You would normally
srun to that allocation.
To be clear, salloc does not create a batchjob, which gets executed on
the remote host. After salloc returns (which migh
Hi Daniel,
I strongly recommend to let SlurmdUser be root.
slurmd starts slurmstepd, but without root privileges, as the specific
user. That is the program, that actually executes the jobscript.
But slurmd needs to bee root, e.g. to execute prolog and epilog scripts,
which in many cases need
