Uncore frequency control device, uncore frequency control method, and uncore frequency control program

An uncore frequency control method of an uncore frequency control device that controls an uncore frequency of a physical server group being pieces of compute in which an App that executes real-time processing is implemented,

• wherein the uncore frequency control device executes:
• acquiring a user requirement related to performance and power consumption;
• changing each of a load amount applied to the compute and an uncore frequency set in the compute and collecting prior data including an App performance value, power consumption, and hardware (HW) operation status data of the compute for a predetermined period;
• referring to the prior data, extracting an uncore frequency that satisfies the user requirement for each of the load amount, and determining a setting value of the uncore frequency for each of the load amount;
• creating a control rule indicating an uncore frequency to be set according to a value of the load amount by replacing each of the load amount with performance data serving as a control determination reference value for determining the uncore frequency by using the setting value of the uncore frequency for each of the load amount;
• acquiring the load amount of a current time point indicated by the HW operation status data from the compute on which the App is executing the real-time processing;
• determining an uncore frequency to be set in the compute by applying the control rule by using the load amount of the current time point acquired from the compute;
• and
• transmitting the uncore frequency that has been determined to the compute and causing the uncore frequency to be set.
