In the context of multitasking systems the scheduling policy is normally preemptive Earliest Deadline First, which, ignoring the overhead of context switching, is sufficient for system loads of less than 100%.
In the context of multitasking systems the scheduling policy is normally priority driven preemptive scheduling. Other scheduling algorithms include Earliest Deadline First, which, ignoring the overhead of context switching, is sufficient for system loads of less than 100%.
