I realized that what I cannot profile, I cannot optimize.
This is why I embarked on a little project in Diffusers, to try to profile important pipelines, identify bottlenecks for torch.compile, and fix them. Got decent results.
I documented the process and invited the community to apply the same.
@ariG23498 decided to take it a notch further by formulating an entire series of tutorials around the topic, starting from compiling simple torch ops and how to make sense of their profile traces.

It’s an incredibly helpful skill to have, especially if you’re in the optimization business. Even if you’re not, it gives a good mental model of what’s going on in those SMs.
