SYSTEMS AND METHODS FOR DYNAMIC TEMPORAL POWER STEERING

摘要

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.

1. A method comprising:
determining, using a power manager, a sequence of phases corresponding to an application comprising tasks for execution on a node, the sequence corresponding to a time interval associated with an energy budget; for each phase, determining a power scaling comprising a measured response in runtime to an increase or decrease in power distributed to a plurality of power domains in the node; based on the power scaling for each phase, determining a temporal power distribution between the phases in the sequence to satisfy the energy budget and improve or optimize runtime performance of the application by the node.
