[slurm-users] introduce short delay starting multiple parallel jobs with srun

Hi John,

I am processing high-resolution MRI data. The processing pipeline itself is in Matlab.
I will suggest updating Slurm, but seeing how far behind we are, it seems to me Slurm is really not a priority for them...

Best,
Renat.

Renat,
  I understand better here.  It does look like job arrays are what you need.
Maybe you could ask for the Slurm version on your HPC to be updated.  I gues that may be difficult.

I am also guessing that you are doing some sort of Big Data task, maybe in Python?

slurm 2.5.0! seeing today's announcement about a double digit version release, that is... ancient!

Best,
Renat.
