Abstract
One embodiment of the present invention sets forth a technique for placing texture barrier instructions within a thread program to advantageously enable efficient and correct operation of the thread program. A thread program compiler statically determines a pending request count needed to progress beyond a particular texture barrier instruction, which blocks execution of subsequent instructions that depend on previously requested data. Each instance of the thread program blocks execution at the barrier instruction until a pending request count condition is satisfied. This technique may advantageously reduce power consumption in a graphics processing unit by eliminating power consumption associated with conventional, generalized scoreboard resources.
