How to profile halide on macos?

[FindHao]

Hi, I'm trying to test halide metal backend on apple silicon. Could you tell me the correct way to profile a python testing example using halide python binding? Is there something like nsight system for NVIDIA we can use to profile? Thanks

We don't have anything metal-specific. I recommend using the native profiling tools available in the instruments app.

You can also do somewhat crude profiling by adding the target feature "-debug", which adds synchronization to GPU API calls and causes a lot of debugging spew, including how long each kernel launch took.

Thanks for your reply! Maybe a silly question, but do you have any suggestions on which native profiling tools for macos with metal backend? Thanks!

I usually just do CPU profiling on macos, but @shoaibkamil would know the answer to that.
