Rohan Anil Calls Megakernel Term Underdefined
The comment responds to a Megakernel Iceberg diagram summarizing GPU kernel concepts on X.
Mark Saroufim shared an iceberg-style graphic outlining seven levels of megakernel concepts in GPU work. The image starts with basic fused kernels at the surface and descends into deeper performance patterns. Rohan Anil replied directly to the post. He said that the more he learns about megakernels the more he dislikes the term. Anil called it very much underdefined. He added that he now only sees performance patterns. The exchange appears among public posts discussing GPU kernel techniques from researchers who work on frameworks like PyTorch and Gemini pretraining.
I think more I understand mega kernel, the more I dislike the term. It’s very much underdefined I only see performance patterns now.
