An alternative would be to have just one partition and to distinguish the the machines via 'features defined in slurm.conf. It depends a bit on how different the machines are and how interested in these differences the users are. > Do you think I can just use the “job size” and “partition” and maybe the “age” > factors ? Maybe you need more information ? I would have thought that in general you want to use 'fairshare' as well, but that obviously depends on what you are trying to achieve. > In any case thanks for your help > > David Regards Loris -- Dr. Loris Bennett (Mr.) ZEDAT, Freie Universität Berlin Email loris.benn...@fu-berlin.de
