An information processing apparatus includes a memory; and a processor coupled to the memory and configured to generate a performance model for calculating a performance value of an application program from a power restriction for each set of parameters of the application program, based on data acquired when a computing apparatus executes the application program for each set of parameters of the application program under each of a plurality of power restrictions; calculate, for each set of parameters of the application program, the performance value of the application program from a first power restriction different from any of the plurality of power restrictions, based on the performance model generated for each set of parameters of the application program; and output a set of parameters of the application program corresponding to a highest performance value of the calculated performance values.

Information processing apparatus, information processing system, and storage medium

An apparatus is configured to calculate consumption power of a processor caused by execution of a program, based on sampling data acquired by event-based sampling. The apparatus determines whether the processor is in an idle state, by using the sampling data of a clock event, where the clock event is an event which generates an interrupt at fixed time intervals when the processor is not in the idle state, and which generates the interrupt when a state of the processor changes from the idle state to a non-idle state. In a case where the processor is in the idle state, the apparatus calculates a first amount of consumption power of the processor in the idle state, based on a second amount of consumption power calculated using a consumption power model and a third amount of consumption power included in the sampling data.

Accurate calculation of consumption power of a processor caused by execution of a program

An information processing device includes a memory to store a power consumption amount for each first time interval output at each first time interval and an occurrence time of a first event which occurs during the first time interval, and a power estimation processor configured to calculate a power consumption amount in the event of an occurrence of the first event, on the basis of the power consumption amount for each first time interval output at each first time interval, and the occurrence time of the first event.

Information processing device, power estimation program and power estimation method

An information processing apparatus includes a memory, and a processor coupled to the memory and configured to obtain performance data of the information processing apparatus at a first time interval repetitively, write the performance data in the memory when a particular value of the performance data indicates a performance decrement of the information processing apparatus, and set a second time interval longer than the first time interval instead of the first time interval for obtaining the performance data when the particular value does not indicate a performance decrement of the information processing apparatus.
