Systems and methods for the processing of EU threads (also known as warps) in a thread group. The status of each EU thread in the group may be monitored, to determine if it is executing or if it is halted and waiting at a synchronization barrier. If certain threshold conditions are met, the waiting EU threads may be preempted to allow execution of threads from another thread group. The threshold conditions may include a minimum number of EUs in use, a minimum number of EU threads in the first thread group that are waiting at the synchronization barrier and/or a maximum number of EU threads that are still executing, and a minimum wait time for one or more of the EU threads waiting at the barrier. |
