....jobs are more important. Users whose interactive work consumes large amounts of processor time may not do well under this methodology, and it may be necessary to retune the priority elevations in response to workload or hardware changes. The VAX VMS 5 scheduler employs this elevation methodology[4]. The second priority elevation methodology is processor usage aging. A scheduler that uses this methodology elevates priorities by gradually forgetting about past processor usage, usually in an exponential fashion. An example is that usage from one minute ago is half as costly as usage within the ....
