[slurm-users] Slurm - UnkillableStepProgram

[Stefan Staeglich]

Hi Chris,

thank you. I've overseen this part.

But someone who is actually using a UnkillableStepProgram stated the opposite 
(that it's executed on the controller nodes). Are you aware of any change 
between Slurm releases? Maybe one of the two parts is just a leftover. Are you 
using a UnkillableStepProgram?

Thank you :)

Best,
Stefan
