Hopefully the previous articles covering linear layout concepts and examples facilitate building a solid understanding of the core generic layer powering various Triton code generation lowering and optimizations. Now let’s turn our focus to those bespoke layouts, which we still consistently interact with when working on Triton compiler internals. Additionally, developers can directly program layouts with Gluon now; writing those bespoke layouts is generally more intuitive than linear layouts.
The previous blog post talked about Triton linear layout concepts, aiming to provide some underlying motivations and an intuitive understanding. As a companion, in this one I’d like to touch on linear layout internals and follow up with some concrete examples to show its usage in action and make it even more comprehensible. Following the same vein, common languages and explanations are preferred instead of mathematical terms and interpretations.
