Thread Importance Based Processor Core Parking And Frequency Selection

A method comprising:

• determining, for each of multiple threads run on a processor core over a given time duration, an importance level of the thread, each importance level being one of multiple different importance levels;
• determining a utilization factor of the processor core based at least in part on the importance levels of the threads run on the processor core over the given time duration;
• determining, based on the utilization factor of the processor core, whether to park the processor core;
• and
• parking the processor core in response to determining to park the processor core based on the utilization factor of the processor core.

A computing device comprising:

• one or more processor cores;
• a thread importance determination module configured to determine an importance level of a first thread scheduled to run on a processor core of the one or more processor cores, the importance level being one of multiple different importance levels;
• and
• a core frequency configuration module configured to determine a frequency range associated with the importance level that is one of multiple different frequency ranges or an energy performance preference value associated with the importance level that is one of multiple energy performance preference values, and to configure the processor core to run at the frequency range or in accordance with the energy performance preference value while running the first thread.
