Abstract
Techniques for scheduling threads for execution in a data processing system are described herein. According to one embodiment, in response to a request for executing a thread, a scheduler of an operating system of the data processing system accesses a global run queue to identify a global run entry associated with the highest process priority. The global run queue includes multiple global run entries, each corresponding to one of a plurality of process priorities. A group run queue is identified based on the global run entry, where the group run queue includes multiple threads associated with one of the processes. The scheduler dispatches one of the threads that has the highest thread priority amongst the threads in the group run queue to one of the processor cores of the data processing system for execution.
