[slurm-users] Fairshare within a single Account (Project)

[Renfro, Michael]

At least from our experience, the default user share within an account is 1, so they'd all stay at the same share within that account. Except for the one faculty who wanted a much higher share than the students within their account, I've never had to modify shares for any users otherwise. So adding and removing users has been a non-issue.

Is it possible to use FairTree  (https://slurm.schedmd.com/fair_tree.html<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fslurm.schedmd.com%2Ffair_tree.html&data=04%7C01%7Crenfro%40tntech.edu%7C257b7bd173204ac8483d08d9e5baa945%7C66fecaf83dc04d2cb8b8eff0ddea46f0%7C1%7C0%7C637793412158657990%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=Fadf2vKHsnEqTztN68CQWDLPKe1ZLIwhRIaSlVtId%2FQ%3D&reserved=0>) to ensure that all users always have equal fairshare. On this account, we have users coming and going relatively often and having fairshare automatically adjusted would simplify the administration.

You can. We use:

sacctmgr show assoc where account=researchgroup format=user,share

to see current fairshare within the account, and:

                sacctmgr modify user where name=someuser account=researchgroup set fairshare=N

to modify a particular user's fairshare within the account.

Hello everyone,

We are a small research group that shares an account on the cluster and we thought we would be able to use usage reports to balance the CPUh from different users: we were wrong.

Is it possible to set up Fairshare<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fslurm.schedmd.com%2Ffair_tree.html&data=04%7C01%7Crenfro%40tntech.edu%7C257b7bd173204ac8483d08d9e5baa945%7C66fecaf83dc04d2cb8b8eff0ddea46f0%7C1%7C0%7C637793412158657990%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=Fadf2vKHsnEqTztN68CQWDLPKe1ZLIwhRIaSlVtId%2FQ%3D&reserved=0> within a single Account (Project)? I am reading the documentation, but as a non-admin, it is difficult for me to know what the configuration steps for something like this would be. If someone would outline the configuration steps in this case, it would save me a great deal of time...

Kind regards,

Tomislav Maric
