摘要： An information processing apparatus includes a processor that acquires a temperature of each of a plurality of arithmetic processing devices. The processor acquires a first raised temperature and a second raised temperature for a first predetermined processing. The first raised temperature is a temperature expected to be raised in a first arithmetic processing device if the first arithmetic processing device executes the first predetermined processing. The second raised temperature is a temperature expected to be raised in a second arithmetic processing device if the first arithmetic processing device executes the first predetermined processing. The second arithmetic processing device is different from the first arithmetic processing device. The processor determines an arithmetic processing device to be assigned to execute the first predetermined processing, based on the temperature of each of the plurality of arithmetic processing devices, the first raised temperature, and the second raised temperature.

摘要： 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.
