Hi Laura,
Thank you for your reply.
Indeed, Prolog is not configured on my machine $ scontrol show config |grep -i prolog Prolog = (null) PrologEpilogTimeout = 65534 PrologSlurmctld = (null) PrologFlags = Alloc,Contain ResvProlog = (null) SrunProlog = (null) TaskProlog = (null)
Does it have to be set on all machines?
