Abstract

A framework for scheduling a number of different applications on a single shared preemptable processor is proposed, such that each application seems to be executing on a slower dedicated processor. A tradeoff is identified and evaluated between how precise a notion of real time (as measured by the granularity of its clock) an application needs supported on the one hand, and the added context-switch costs imposed by our scheduling framework on the other.
