SYSTEMS AND METHODS FOR DYNAMIC SPATIAL POWER STEERING

摘要

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.

1. An apparatus comprising:
a power manager comprising logic, at least a portion of which includes hardware, the power manager comprising:
a phase module to determine a plurality of phases of an application, wherein each of the plurality of phases comprises a segment of the application that exhibits operational behavior different than that of the other phases; anda spatial power steering module to, for each of the plurality of phases, determine a spatial power distribution between a plurality of power domains based on a performance metric.
