Abstract:
Techniques and apparatuses for providing power-aware thread scheduling and dynamic use of processors are disclosed. In some aspects, a multi-core system is monitored to determine core activity. The core activity may be compared to a power policy that balances a power savings plan with a performance plan. One or more of the cores may be parked in response to the comparison to reduce power consumption by the multi-core system. In additional aspects, the power-aware scheduling may be performed during a predetermined interval to dynamically park or unpark cores. Further aspects include adjusting the power state of unparked cores in response to the comparison of the core activity and power policy.
