Abstract
Methods and systems may synchronize workloads across local thread groups. The methods and systems may provide for receiving, at a graphics processor, a workload from a host processor and receiving, at a plurality of processing elements, a plurality of threads that from one or more local thread groups. Additionally, the processing of the workload may be synchronized across the one or more thread groups. In one example, the global barrier determines that all threads across the thread groups have been completed without polling.
