Dear Loris, Thanks for your response !
I'm going to look on this features in slurm.conf. I only configured the CPUs, Sockets.... per node. Do you have any example or link to explain me how it's working and what can I use ? My goal is to respond to people needs and launch their jobs as fast as possible without losing time when one partition is idle whereas the others are fully loaded. That's why I thought the fair share factor was the best solution Thanks Greetings ------------------------------ David WALTER The computer guy [email protected] 01/44/32/27/94 INSERM U960 Laboratoire de Neurosciences Cognitives Ecole Normale Supérieure 29, rue d'Ulm 75005 Paris -----Message d'origine----- De : Loris Bennett [mailto:[email protected]] Envoyé : lundi 16 janvier 2017 13:12 À : David WALTER Cc : slurm-dev Objet : Re: [slurm-dev] A little bit help from my slurm-friends Hello David, David WALTER <[email protected]> writes: > Hello everyone, > > I need some advice or some good practices as I’m a new SLURM’s > administrator… in fact a new cluster manager ! > > Everything is OK, jobs running well etc… But now I would like to > configure priority on jobs to improve the efficiency of my cluster.

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 [email protected]
