Abstract: Tasks may be scheduled on more than one processor to allow the processors to operate at lower processor frequencies and processor supply voltages. Multiple processors executing tasks in parallel at lower frequencies and supply voltages may allow completion of the tasks by deadlines at lower power consumption than a single processor executing all tasks at high frequencies and supply voltages. Power efficiency of a computer system may be improved by using a combination of processors executing tasks using a combination of earliest deadline first (EDF), earliest deadline last (EDL), and round robin (RR) queue management methods.

Abstract: Tasks may be scheduled on more than one processor to allow the processors to operate at lower processor frequencies and processor supply voltages. In particular, realtime tasks may be scheduled on idle processors without context switching an existing executing tasks. For example, a method of executing tasks on a plurality of processors may include receiving a new task with an earlier deadline than an executing task; determining whether an idle processor is available; and when an idle processor is available, executing the new task on the idle processor.
