ABSTRACT:
Execution units process commands from one or more command queues. Once a command is available on the queue, each unit participating in the execution of the command atomically decrements the command's work groups remaining counter by the work group reservation size and processes a corresponding number of work groups within a work group range. Once all work groups within a range are processed, an execution unit increments a work group processed counter. The unit that increments the work group processed counter to the value stored in a work groups to be executed counter signals completion of the command. Each execution unit that access a command also marks a work group seen counter. Once the work groups processed counter equals the work groups to be executed counter and the work group seen counter equals the number of execution units, the command may be removed or overwritten on the command queue.
