[MDAPI] Does Query-Based Collection for OpenCL collects metrics per kernel?

1,557 Views

I'm experimenting with collecting metrics using MDAPI, and I have a question about per-kernel metrics.

According to the document on pti-gpu repository, I can collect metrics per kernel.

I wonder if the collected metrics are based on each kernel or the overall system, when multiple kernels are running at the same time.

For example, if two kernels with different cache efficiency runs together, are the collected cache hit rates higher one and lower one, or just two averaged results?

Thank you in advance.
