Abstract: The present disclosure is directed to dynamically prioritizing, selecting or ordering a plurality threads for execution by processor circuitry based on a quality of service and/or class of service value/indicia assigned to the thread by an operating system executed by the processor circuitry. As threads are executed by processor circuitry, the operating system dynamically updates/associates respective class of service data with each of the plurality of threads. The current quality of service/class of service data assigned to the thread by the operating system is stored in a manufacturer specific register (MSR) associated with the respective thread. Selection circuitry polls the MSRs on a periodic, aperiodic, intermittent, continuous, or event-driven basis and determines an execution sequence based on the current class of service value associated with each of the plurality of threads.

Abstract: A data processing system with technology for dynamically grouping threads includes a machine-readable medium and first and second cores, each with multiple logical processors (LPs). The system also comprises an operating system which, when executed, enables the system to select an LP to receive a new low-priority thread and to assign the new low-priority thread to the selected LP. The operation of selecting an LP to receive the new low-priority thread comprises, when the first core has multiple idle LPs, automatically determining whether the second core has an idle LP and a busy LP that is executing a current low-priority thread. In response to determining that the second core has an idle LP and a busy LP that is executing a current low-priority thread, the system automatically selects the idle LP in the second core to receive the new low-priority thread. Other embodiments are described and claimed.
