SLURM Devs,
We're starting to realized the niceties of SLURM Job Arrays in my group,
which got me to thinking. I was wondering if there was every any thought
as to perhaps allowing non-numerical array indexes a la:
#SBATCH --array=a,b,c,d
or
#SBATCH --array=temperature,uwind,vwind
where you could use the very nice properties of SLURM arrays but with a
more generic set of substitutions to pass along to the script being run.
Obviously, a user wouldn't be able to do fancy things like 1-10 (though
I guess a-z is valid in ASCII-land) or 1-10:4 or 1-30%4, only
comma-delimited.
And one can, with shell script arrays, emulate an effect thing now
(reference an array with the SLURM_ARRAY_TASK_ID: 1=temp, 2=uwind...)
with a little work.
Of course, I realize this is more problematic than just parsing a list
with commas since you could have job-ids that are now alphanumeric
(scontrol hold 123409_temperature), you have to start thinking about
Unicode, etc., but I just wondered if it was ever in any thoughts.
Thanks,
Matt
