Patent ID: 8850234

Claim:
An information processing apparatus capable of communicating with a power management server, the information processing apparatus comprising: devices operating therein; a processor executing an operation including: measuring power consumptions of the devices and outputting power consumption data; receiving, from the power management server, application-setting conditions designating operational conditions of the devices for measuring the power consumptions of the devices, setting the operational conditions of the devices according to the application-setting conditions, and executing an application program to measure reference power consumptions of the devices for executing the application program; transmitting the power consumption data outputted to the power management server, the power consumption data including the reference power consumptions; receiving, from the power management server, normalized reference power consumption calculated from reference power consumptions of a plurality of information processing apparatuses connected with the power management server, and calculating a normalized power consumption from the normalized reference power consumption and the reference power consumptions using variation of characteristics of the information processing apparatuses; and indicating the normalized power consumption and identifying conditions among the operational conditions set that are needed to maintain a target power consumption across the variation of characteristics of the plurality of information processing apparatuses.
