Covers how to set up profiling, read profiler tables and Chrome traces in Perfetto, understand the CPU-to-GPU dispatch chain, interpret overhead-bound vs compute-bound behavior, and observe what torch.compile actually does at the kernel level. Includes a practical cheatsheet for common trace patterns and their meanings. ## Full article daily.dev links to this article rather than hosting it.
