Hi all, I just thought I'd get a sanity check from you all before I actually make the SGE changes. As a reminder, we basically want to implement a fairness scheme solely based on user. So if User-A launches 10 jobs, and User-B launches 10 jobs--and let's say there is only one execution host--then we want User-A and User-B's jobs to dispatched in a round-robin fashion.
Based on the information you folks have provided, it seems the Functional Policy is the most appropriate for us. The Share Tree Policy's historical usage characteristic would probably not be appreciated by some folks I'm afraid (unless the lifetime parameter could be set to something on the order of minutes--which the documentation seems to state is not possible). Regarding how to actually make this change: I was planning to use the Policy Configuration tool in QMON and simply selecting the "Functional Policy" button. We don't have too many users at this point so I plan to add them manually and then set the number of total functional tickets to be 200 per user (e.g.). And I will Clear the "Share Functional Ticket" button so that each job has the same relative priority. Am I close? Anything I've missed or misunderstood?
