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.

摘要： A computer readable storage medium including executable instructions for heuristics-based task scheduling. Instructions include receiving a first event notification associated with a first event, where the first event is determined from the first event notification. Instructions further include determining whether a predicate for an action is satisfied by the first event, where the action predicate, the action, and an action parameter are associated with a task object in a task pool. Instructions further include obtaining the action parameter when the action predicate is satisfied by the first event, where a priority is assigned using a heuristics policy to the task object based on the action parameter. Instructions further include inserting the task object into a task queue using the assigned priority. The action associated with the task object is performed by an execution thread. The performance of the action is a second event associated with a second event notification.

摘要： A system for self-tuning hardware resources includes a processor, a hardware resource, an operating system (OS), a metric monitoring unit (MMU), and a configuration engine (CE). The OS determines: the hardware resource; a metric for monitoring the hardware resource; a hardware resource management policy for the hardware resource; and a primary and secondary sub-ranges for the metric. The OS sends a hardware resource management policy directive to the CE. The MMU monitors the hardware resource to obtain data for the metric. The CE receives the hardware resource management policy directive, determines the primary and secondary sub-ranges from the hardware resource management policy directive, obtains data for the metric from the MMU. When data is outside the primary sub-range and inside the secondary sub-range, the CE determines and executes a hardware resource optimization routine to bring hardware resource utilization into compliance with the primary sub-range.
