The Pittsburgh Supercomputing Center has developed a job scheduler to work with the HP AlphaServer SC architecture that allows us to implement specific site policies. Three specific features of the scheduler are discussed: 1) Mini drains allow us to run a continuous stream of large jobs without draining the entire machine and achieve high overall system utilization, 2) Reservations allow us to accommodate priority work on specific processors, 3) Co-scheduling provides jobs with additional services such as visualization nodes, application gateway nodes, and data staging.
