Open Projects

Below is a list of projects that can be suitable for Google Summer of Code (GSOC) or just for someone to get started with contributing to MLIR. See also the “beginner” issues on the bugtracker. If you’re interested in one of these projects, feel free to discuss it on the MLIR section of the LLVM forums or on the MLIR channel of the LLVM discord server. The mentors are indicative and suggestion of first point of contact for starting on these projects.

• Building an MLIR interpreter (mentor: Mehdi Amini). At the moment we have constant folding implemented as an eager folding on a per op basis. This relies on attribute storage and is very inefficient. It also does not mesh well with control-flow (symbolic execution of a for loop for example). The idea would be to revamp this to ultimately allow to have features like “constexpr evaluation” of functions in MLIR.
• llvm-canon kind of tool for MLIR (mentor: Mehdi Amini, Jacques Pienaar)
• MLIR sparsifier (aka sparse compiler) starter tasks (mentor: Aart Bik)
• Improving mlir-reduce (mentor: Jacques Pienaar, Mehdi Amini). This tools is basic in its current form and needs investment to make it really useful in practice. That means developing new reduction pattern and strategies. Possibly interfaces for dialects to plug into injecting custom logic.
