Initial object shader run for graphics workload distribution

A method, comprising:

• executing, by multiple shader sub-units of a computing device, shader programs including object shaders and mesh shaders;
• for a given object shader, the computing device:
• launching an initial version of the given object shader to determine a number of meshlets to be generated by the given object shader, wherein the initial version of the given object shader does not commit side effects to architectural state of the computing device;
• and
• selecting, based on the determined number of meshlets, a number of the multiple shader sub-units to execute a complete version of the given object shader at least partially in parallel.

A non-transitory computer-readable storage medium having stored thereon design information that specifies a design of at least a portion of a hardware integrated circuit in a format recognized by a semiconductor fabrication system that is configured to use the design information to produce the circuit according to the design, wherein the design information specifies that the circuit includes:

• shader circuitry configured to execute shader programs including object shaders and mesh shaders, wherein the shader circuitry includes multiple distributed shader sub-units;
• vertex control circuitry configured to, for a given object shader:
• launch an initial version of the given object shader to determine a number of meshlets to be generated by the given object shader, wherein the initial version of the given object shader does not commit side effects to architectural state of the circuit;
• and
• select, based on the determined number of meshlets, a number of the multiple distributed shader sub-units to execute a complete version of the given object shader at least partially in parallel.
