METHOD OF DYNAMICALLY CONTOLLING POWER IN MULTICORE ENVIRONMENT

摘要

Provided is a method of dynamically controlling power in a multicore environment including a multicore processor which includes a plurality of cores and a scheduler. The method includes determining whether a management policy is set, collecting frequency change information used to change frequencies of the plurality of cores when it is determined that the management policy is set, calculating an average load of each core on a basis of the frequency change information, calculating an average frequency of each core according to the calculated average load of each core, comparing the average frequency of each core and a predetermined threshold value, and setting a next frequency of each core according to the comparison result.

1. A method of dynamically controlling power in a multicore environment including a multicore processor which includes a plurality of cores and a scheduler, the method comprising:
determining, by the scheduler, whether a management policy is set; when it is determined that the management policy is set, by the scheduler, collecting frequency change information used to change frequencies of the plurality of cores; calculating an average load of each core on a basis of the frequency change information, and calculating an average frequency of each core according to the calculated average load of each core; comparing the average frequency of each core and a predetermined threshold value; and setting a next frequency of each core according to the comparison result.
