Abstract
A multi-core processor system includes a core configured to detect among multiple cores, a state of migration of first software from a first core to the core whose specific processing capacity value is lower than that of the first core; and set the processing capacity value of the first core at a time of the detection to be a processing capacity value that is lower than that before the migration when detecting the state of migration.
Claims7
A multi-core processor system comprising a core configured to:
- detect among multiple cores, a state of migration of first software from a first core to the core whose specific processing capacity value is lower than that of the first core;
- and
- set the processing capacity value of the first core at a time of the detection to be a processing capacity value that is lower than that before the migration when detecting the state of migration.
A power control method executed by a core, the power control method comprising:
- detecting among multiple cores, a state of migration of first software from a first core to the core whose specific processing capacity value is lower than that of the first core;
- and
- setting the processing capacity value of the first core at a time of the detection to be a processing capacity value that is lower than that before the migration when the state of migration is detected at the detecting.
A computer-readable recording medium storing a program causing a core to execute a power control process comprising:
- detecting among multiple cores, a state of migration of first software from a first core to the core whose specific processing capacity value is lower than that of the first core;
- and
- setting the processing capacity value of the first core at a time of the detection to be a processing capacity value that is lower than that before the migration when the state of migration is detected at the detecting.
