摘要
A system for dispatching a thread to a resource obtains a thread and utilization data for all resources. The system determines if there is a thread-resource affinity. The system uses thread-resource affinity to identify a resource and a timestamp for when the thread last completed executing on the resource. The system determines if the resource qualifies under a dispatch policy. The system uses utilization data to determine a timestamp for when the resource last transitioned to a not powered state. When the second timestamp precedes the first timestamp, the system dispatches the thread to the resource and generates a power management event. The system determines if the power management event satisfies a throttle policy. The system discards the power management event when throttle policy is unsatisfied and determines whether to adjust the current power state of the resource based on the power management event when throttle policy is satisfied.
