Abstract
Techniques are disclosed relating to dynamically adjusting buffering for distributing compute work in a graphics processor. In some embodiments, the graphics processor includes shader circuitry configured to process compute work from a compute kernel, multiple distributed workload parser circuits configured to send compute work to the shader circuitry, primary workload parser circuitry configured to send, via a communications fabric, compute work from the compute kernel to the distributed workload parser circuits, and buffer circuitry configured to buffer compute work received by one or more of the distributed workload parser circuits from the primary workload parser circuitry. In some embodiments, the graphics processor is configured to dynamically adjust a limit on the number of entries used in the buffer circuitry based on information indicating complexity of the compute kernel. This may advantageously maintain launch rates while reducing or avoiding workload imbalances, in some embodiments.
