Open MLIR Meeting 11-02-2023: A MPI Dialect Proposal

MPI is at the heart of most modern massively parallel workloads, serving as the fundamental building blocks on which high-performance codes are built. With MLIR having proven itself well as a compiler for single-node workloads already, there is a lot interest in seeing MLIR scale up as a compiler for more massively parallel workloads. We are interested in bringing an MPI dialect into MLIR to serve as the foundation for a robust and efficient stack of dialects for distributed and even massively parallel workloads. This presentation proposes a first patch that introduces a small subset of the MPI dialect. We want to discuss and review the design decisions made while creating this patch with the community and talk about the direction and scope of further development.
