Abstract

In a computer room including information processing devices and air conditioners, power saving of the computer room by means of optimization of workload allocation to the information processing devices is achieved in a short time. There, a coefficient of air conditioner performance with respect to the information processing device (device-specific COP) is calculated for each air conditioner. Further, a device-associated power consumption expression representing a total of device power and air conditioner power is created for each information processing device. Also, power consumption of the entire computer room is calculated from the device-associated power consumption expression of the information processing devices. Also, workload allocation is determined by using power saving performance evaluation indexes based on the device-associated power consumption expression of the information processing devices. Further, output of the air conditioner is controlled based on a result of the air conditioner power calculation.
