As evidenced by numerous responses, my understanding was incorrect. Thanks all for setting me straight, saved me quite a bit of trouble.

Our Unix group and Slurm allocation names are not the same (groups have a two letter cluster name prefix, and allocations get a suffix indicating the source of the funding, and many users belong to multiple allocations with the same group). But you can test it; in particular, if you do "sacctmgr show user USERNAME" where USERNAME is some user on your system, it should list something like: sacctmgr show user payerle User Def Acct Admin ---------- ---------- --------- payerle test-paid None In this case, my default account is test-paid, and that will be used if I do not explicitly specify an account when submitting a job. (And we do not have a test-paid Unix group, and the closest unix group I belong to is zt-test). Actually, the behavior you describe with the groups is new to me (although Google's AI also suggested something similar); I cannot find much in the docs to support either your or my description of Slurm behavior. All I know is that is how our Slurm behaves, and it has behaved that way in the ~10 years we have been using it. It is possible the behavior is dependent upon other configuration settings in Slurm (Slurm is like that), However, in https://slurm.schedmd.com/sacctmgr.html<https://urldefense.com/v3/__https:/slurm.schedmd.com/sacctmgr.html__;!!NiUAmZJ8c1GNWg!TeNLvuwMzxb0WWctSifTwrvgKXB0OprW1-kFqL8wmG0N3vPmXNemkq-We3Qq-Q7kwb7bX5Kl6_cMAS8LSblH8z7GdYkdPE_3zMwBq88$>, under Specifications for Users, it described the DefaultAccount field <quote> DefaultAccount=<account> Identify the default bank account name to be used for a job if none is specified at submission time. </quote> I suggest you test it out; create a new account + group and user in the account; verify expected account defaulting when using sbatch, examine the defaultaccount for the user (sacctmgr show user), then change the name of the group w/out changing the defaultaccount and verify account defaulting works as expected.

Are you sure about that? I've never heard of such defaulting. My understanding is that without --account, sbatch/salloc will use what has been set as the user's DefaultAccount in Slurmdbd. That can be set explicitly with sacctmgr first time a user is created, but failing that, the account of the first user-account association of the user will be used as DefaultAccount. -- B/H -- slurm-users mailing list -- slurm-users@lists.schedmd.com<mailto:slurm-users@lists.schedmd.com> To unsubscribe send an email to slurm-users-le...@lists.schedmd.com<mailto:slurm-users-le...@lists.schedmd.com> -- Tom Payerle DIT-ACIGS/Mid-Atlantic Crossroads paye...@umd.edu<mailto:paye...@umd.edu> 5825 University Research Park (301) 405-6135 University of Maryland College Park, MD 20740-3831
