Completion Signaling Techniques in Distributed Processor

A method, comprising:

• maintaining, by a distributed workload parser circuit, for each of a set of shader processors, a data structure that specifies a count of workgroup completions for one or more kernels processed by the shader processor, wherein the distributed workload parser circuit is connected to a master workload parser circuit via a communications fabric;
• determining, by the distributed workload parser circuit, for the set of shader processors based on counts of workgroup completions for a first kernel, an aggregate count of completions to report for the first kernel;
• sending, by the distributed workload parser circuit, the aggregate count to the master workload parser circuit over the communications fabric;
• and
• adjusting, by the distributed workload parser circuit, the data structures to reflect counts included in the aggregate count.

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:

• a plurality of shader processors configured to perform operations for compute workgroups included in compute kernels processed by the circuit;
• a master workload parser circuit;
• a plurality of distributed workload parser circuits;
• a communications fabric connected to the plurality of distributed workload parser circuits and the master workload parser circuit;
• where at least one of the distributed workload parser circuits is configured to:
• maintain, for each of a set of the shader processors, a data structure that specifies a count of workgroup completions for one or more kernels processed by the shader processor;
• determine, for the set of shader processors based on counts of workgroup completions for a first kernel, an aggregate count of completions to report for the first kernel;
• send the aggregate count to the master workload parser circuit over the communications fabric;
• and
• adjust the data structures to reflect counts included in the aggregate count.
