Abstract
One embodiment sets forth a method for guiding the order in which a parallel processing subsystem executes memory copies. A driver creates semaphores for all but the lowest priority included in a plurality of priorities and associates one priority with each copy hardware channel included in the parallel processing subsystem. The driver then aliases prioritized streams to the copy hardware channels based on the priorities. Upon receiving a request to execute a memory copy within one of the streams, the driver inserts commands into the aliased copy hardware channel. These commands use the semaphores to direct the parallel processing subsystem to execute the memory copy based on the priority of the copy hardware channel. Advantageously, by assigning priorities to streams and, subsequently, strategically requesting memory copies within the prioritized streams, an application developer may fine-tune their software application to increase the overall processing efficiency of the software application.
