That would be too easy :-) I'm guessing my best bet would be to set CPUs=32 and a default ntasks of 2 and override it if need be (I'd never get my users to do this reliably)
Any idea where I'd set this? slurm.conf does not appear to have an entry for it ________________________________ From: Chrysovalantis Paschoulas [[email protected]] Sent: 27 November 2014 14:54 To: slurm-dev Subject: [slurm-dev] Re: overcommit on independent jobs Try the option "--overcommit" from srun. Check also the man page. You can not exceed the MAX_TASKS_PER_NODE limit of your configuration.

We could just run everything else with --ntasks=2, but I was wondering if there was a way to do --ntasks=0.5 -- Michael Lush Computer Officer CR-UK Genetic Epidemiology Unit University of Cambridge Strangeways Research Laboratory Worts Causeway, Cambridge CB1 8RN Tel.: +44 (0)1223 748643 Web: http://ccge.medschl.cam.ac.uk/ ________________________________ ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
