Beschreibung
Zusammenfassung:	A method of dynamically controlling power within a multicore central processing unit is disclosed and includes executing a plurality of virtual cores, virtually executing one or more tasks, one or more threads, or a combination thereof at the virtual cores, and physically executing one or more tasks, one or more threads, or a combination thereof at a zeroth physical core. The method may further include receiving a degree of parallelism in a workload of a plurality of virtual cores and determining whether the degree of parallelism in the workload of the virtual cores is equal to a first wake condition.
