Abstract: Apparatus and methods may provide for subscribing a thread to a resource monitor through a machine specific register and subscribing the thread to a class of service through the machine specific register. The resource monitor or the class of service for the thread may be changed without interrupting the thread. The power allocated to the processor core may be changed based on the selected class of service for the thread.

Abstract: Apparatus, systems, and methods provide dynamic power steering that includes determining a sequence of phases of an application in a node. The sequence corresponds to a time interval associated with an energy budget. For each phase, the dynamic power steering includes determining a power scaling comprising a measured response to an increase or decrease in power distributed to a plurality of power domains in the node, and based on the power scaling for each phase, determining a temporal power distribution between the phases in the sequence to satisfy the energy budget.

Abstract: Apparatus, systems, and methods provide dynamic spatial power steering among a plurality of power domains in the computer system on a per phase basis of a particular application. Dynamic spatial power steering may include, for example, determining a plurality of phases corresponding to an application comprising tasks for execution on a processing node. determining a spatial power distribution between a plurality of power domains on the processing node based on a performance metric for each phase, monitoring the application to detect a current phase, and applying the spatial power distribution correspond to the current phase to the plurality of power domains.

Abstract: Apparatus, systems, and methods provide an interface between a plurality of hardware resources of a node and a power manager. The interface is configured to define one or more resource groups to expose to the power manager for power measurement and control, assign the plurality of hardware resources to the one or more resource groups, and provide a power allowance to each resource group.
