[Moabusers] Limit number of jobs of a group over a period of time ?

[Michael Santos]

Hi Chris,

	I think the closest you could come to this would be to use  
fairshare.  You couldn't use jobs as a metric (I think), but would  
have to use some variant on processor-seconds consumed.  You could  
set FSINTERVAL to 24 hours and set FSDEPTH to only have one window.   
If your high-level goal is to stop one group from dominating  
resources, I think fairshare is a reasonable direction to go in,  
unless you really need to measure jobs run and not processor- 
seconds.  You can also do thing like 'disregard fairshare unless a  
group is using more than XX% of the resources' (using FSTARGET with a  
ceiling) so that it only kicks in when one group is really dominating.

Good luck,
