POWER-SAVING STREAM SCHEDULING AND DYNAMIC USE OF PROCESSORS Russian patent published in 2014 - IPC G06F1/32 

FIELD: information technology.

SUBSTANCE: method involves determining which cores of multiple cores are actively working; creating a core parking mask using a bit value to represent a parked or unparked status of a core; determining stream processor affinity masks representing one or more cores on which a stream is assigned to be processed; providing at least a portion of the performance and power saving plan for the cores by combining an inversion of the core parking mask and the stream processor affinity masks using an "AND" operator to create an available processor set; calculating which cores are designated as parked or unparked based at least in part on the available processor set; and parking at least one of the cores actively working based at least in part on the power policy indicating that at least one of the cores actively working is designated as a parked core.

EFFECT: reduced power consumption.
