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.
Layout is a core concept in Triton for representing and optimizing distribution mappings from source problems to the target hardware compute and memory hierarchy. In this blog post I will talk about linear layout in Triton, the new unifying mechanism over existing bespoke layouts for different purposes. The aim is to provide motivation and an intuitive understanding of linear layout; I will rely on examples and illustrations instead of theories and proofs.
