Thanks. I thought that might be the answer . I was talking to someone the other day about managing resources at a per-user or per project / group level and I wanted to make sure I understood the TBF feature before I made any further reply .

Nope, a rule is matched by comparing the exact string of jobid. But it is allowed to set multiple jobid for each rule. And it is not hard to add extension if wildcards are necessary. nrs_tbf_jobid_list_match() is the function that we need to change.

Can the jobid be wildcarded? e.g. *:<uid>.

Hi Andreas, we've push a manual patch a month ago. Sorry, we didn't post a comment here. Please let us know if there is anything else we need to do.

Li Xi, is there any progress on adding this documentation to the manual? Is there someone else at DDN/Clogeny that could help you with this effort?

Hi Andreas,

Thank you very much! I will start working on it.
