Abstract
Systems and methods for thread group kickoff and thread synchronization are described. One method is directed to synchronizing a plurality of threads in a general purpose shader in a graphics processor. The method comprises determining an entry point for execution of the threads in the general purpose shader, performing a fork operation at the entry point, whereby the plurality of threads are dispatched, wherein the plurality of threads comprise a main thread and one or more sub-threads. The method further comprises performing a join operation whereby the plurality of threads are synchronized upon the main thread reaching a synchronization point. Upon completion of the join operation, a second fork operation is performed to resume parallel execution of the plurality of threads.
