Hint for Scheduling Graphics Ray Tracing Work

A non-transitory computer-readable medium having instructions of a shader program stored thereon that are executable by a computing device to perform operations comprising:

• detecting a hint in the shader program that a single-instruction multiple-data (SIMD) group has an upcoming ray intersect command for ray intersect accelerator circuitry;
• in response to the hint, adjusting a scheduling priority level for the SIMD group based on a resource usage indication provided by the ray intersect accelerator circuitry;
• and
• scheduling instructions of the SIMD group according to the adjusted scheduling priority level.

A method, comprising:

• detecting, by a computing system, a hint in a shader program, wherein the hint indicates that a single-instruction multiple-data (SIMD) group has an upcoming ray intersect command for ray intersect accelerator circuitry;
• in response to the hint, the computing system adjusting a scheduling priority level for the SIMD group based on a resource usage indication provided by the ray intersect accelerator circuitry;
• and
• scheduling, by the computing system, instructions of the SIMD group according to the adjusted scheduling priority level.
