Abstract: A processor determines a target value of a temperature of a processing unit included in the information processing system on the basis of the temperature of the processing unit when first power consumption indicates a relatively low power consumption by referring to correlation information that indicates a change in the first power consumption, which is a total sum of second power consumption of the processing unit and third power consumption of an air-conditioning machine included in the information processing system, with respect to a change in the temperature of the processing unit. Then, the processor outputs a control signal for controlling the air-conditioning machine on the basis of the target value.
Abstract translation: 当处理单元的温度指示相对较低的功耗时，处理器通过参考指示相对较低功耗的相关信息来确定包括在信息处理系统中的处理单元的温度的目标值 相对于处理单元的温度变化，第一功率消耗是处理单元的第二功率消耗和信息处理系统中包括的空调机的第三功耗的总和。 然后，处理器基于目标值输出用于控制空调机的控制信号。
