Re: [HTCondor-users] Official documentation on interaction between quotas and (user) priorities?

[Jeff Templon <templon@xxxxxxxxx>]

Hi Greg,

Cole gave me the procedure to make PRs for the docs a while back, I might need to make use of that.  Iâve found several other gotchas - itâs not that the docs are wrong, itâs just that they leave out a few things that will sneak up and smack you upside the head :)

When we change group definitions or membership, we don't retroactively go back and re-account for old usage for the new definition of the groups.  I'll try to add something meaningful and useful to the manual.

The documentation is clear on the quotas and on the user priorities, what is not clear is the interaction between the two.  The best I could find is this passage

It does this one group at a time. By default, it goes in âstarvation group order.â That is, the group whose current usage is the smallest fraction of its quota goes first, then the next, and so on.
