Abstract

This article is primarily meant to present an early case study on using MLIR, a new compiler intermediate representation infrastructure, for high-performance code generation. Aspects of MLIR covered in particular include memrefs, the affine dialect, and polyhedral utilities and pass infrastructure surrounding those. This article is also aimed at showing the role compiler infrastructure could play in generating code that is competitive with highly tuned manually developed libraries, albeit in a more modular, reusable, and automatable way.

    • For BLAS in particular, this paper can give you an idea of some of MLIR's capabilities: https://arxiv.org/pdf/2003.00532.pdf (But maybe you already know them better than I do.) LoopVectorization can't do many of these yet, so its performance will fall off a cliff shortly after…
