Title: Using MLIR Linalg Category Ops for Smarter Compilation
Speaker: Javed Absar

-----
Linalg dialect of MLIR recently added category ops as an intermediate abstraction between the two existing forms: named ops and generic ops. A mechanism (-linalg-morph-ops=_-to-_) to move between these forms was also introduced. When something new appears, adoption is often slow due to existing workflows and lack of awareness. This talk will motivate the reason for this additional representation, explain what now exists and how to benefit from it, and show how category ops can help certain compilation flows.
