[slurm-users] Slurm commands for launching tasks: salloc and sbatch

[Mike Mikailov]

Thank you Loris, for the further clarifications. The only question is who will wait forever in interactive mode? And how practical is it?

Interactive mode is what its name implies - interactive, not queueing.

It would make more sense if the default setting for deadline would be set to a reasonable time not indefinite in Slurm.
