Abstract
An information processing apparatus includes a processor that is capable of switching a performance level to one of a plurality of performance levels with different power consumption, and a storage unit that stores a program for controlling the performance level of the processor. The processor executing the program detects the periodicity of load variation of the information processing apparatus, and changes, according to the periodicity of the load variation, a determination interval for determining whether to switch the performance level of the processor.
Claims6
An information processing apparatus comprising:
- at least one processor configured to be capable of switching a performance level to one of a plurality of performance levels with different power consumption;
- and
- a storage unit configured to store a program for controlling the performance level of the at least one processor, wherein
- the at least one processor executing the program performs a procedure including:
- detecting times when the performance level of the processor was increased from a first level to a second level, the first level being lower than a threshold, the second level being equal to or greater than the threshold;
- calculating an average time period between the detected times;
- and
- changing, according to the calculated average time period, a determination interval for determining whether to switch the performance level of the processor.
A load control method executed by a computer including a processor capable of switching a performance level to one of a plurality of performance levels with different power consumption, the load control method comprising:
- detecting times when the performance level of the processor was increased from a first level to a second level, the first level being lower than a threshold, the second level being equal to or greater than the threshold;
- calculating an average time period between the detected times;
- and
- changing, according to the calculated average time period, a determination interval for determining whether to switch the performance level of the processor.
A non-transitory computer-readable recording medium storing a load control program causing a computer including a processor capable of switching a performance level to one of a plurality of performance levels with different power consumption to perform a process comprising:
- detecting times when the performance level of the processor was increased from a first level to a second level, the first level being lower than a threshold, the second level being equal to or greater than the threshold;
- calculating an average time period between the detected times;
- and
- changing, according to the calculated average time period, a determination interval for determining whether to switch the performance level of the processor.
