Fairshare Scheduling
To configure any kind of fairshare scheduling, you should understand the following
concepts:
◆ User share assignments
◆ Dynamic share priority
◆ Job dispatch order
You can configure fairshare at either host level or queue level. If you require more
control, you can implement hierarchical fairshare. You can also set some additional
restrictions when you submit a job.
To get ideas about how to use fairshare scheduling to do different things, see Ways
to Configure Fairshare on page 324.
