The highlight has been the creation of an open-source modular and reusable compiler infrastructure for machine learning and artificial computations called MLIR (Multi-level Intermediate Representation), where the faculty member was a co-founder and the key contributor to its polyhedral compiler aspects. MLIR provides a new intermediate representation to progressively lower dataflow compute graphs through loop nests to high-performance target-specific code. It is meant to serve as the infrastructure to drive compilation of the next generation of programming languages/models to a wide variety of general-purpose as well as specialized hardware. Within its first year, the project has had significant adoption in the compiler stacks of several ML/AI programming models.
