TileIR Internals
Summary
Henry Zhu's TileIR Internals post dives into the internals of NVIDIA's TileIR, tracing how CuTile code flows through a series of MLIR dialects and into GPU machine code. It explains the tile-centric model, the dialects involved, and the end-to-end compilation pipeline for a Mixture-of-Experts kernel, highlighting performance and portability considerations. The piece blends narrative with IR dumps and practical details on the passes and tooling used.
