[slurm-users] Background tasks in Slurm scripts?

Good morning,

yesterday I came across a Slurm (sbatch) script that, after doing some stuff in the foreground, runs another executable in the background - and doesn't "wait" for it to finish - literally the last line of the script is

executable &

(and that executable is supposed to take several 10 seconds or more to finish)

How would Slurm handle this? Will the end of the script immediately trigger the job epilog, and what would happen to the leftover task? This certainly is discussed somewhere in the manual pages and other documentation but up to now I failed to find that place...

Thanks, Steffen
