Abstract
A method for executing an application program using streams. A device driver receives a first command within an application program and parses the first command to identify a first stream token that is associated with a first stream. The device driver checks a memory location associated with the first stream for a first semaphore, and determines whether the first semaphore has been released. Once the first semaphore has been released, a second command within the application program is executed. Advantageously, embodiments of the invention provide a technique for developers to take advantage of the parallel execution capabilities of a GPU.
