Techniques for Managing Power and Performance of Multi-Socket Processors

摘要

Examples are disclosed for managing power and performance of multi-socket processors. In some examples, a utilization rate of a first processor circuitry in a first processor socket may be determined. An active memory ratio of a cache for the first processor circuitry may be compared to a threshold ratio or a data traffic rate between the first processor circuitry and a second processor circuitry in a second processor socket may be compared to a threshold rate. According to some examples, a first power state of the first processor circuitry may be changed based on the determined utilization rate. The first power state may also be changed based on the comparison of the active memory ratio to the threshold ratio or the comparison of the data traffic rate to the threshold rate.
