Coupe is a mesh partitioning platform. It provides solutions to solve different variants of the mesh partitioning problem, mainly in the context of load-balancing parallel mesh-based applications. From partitioning weights ensuring balance to topological partitioning that minimizes communication metrics through geometric methods, Coupe offers a large panel of algorithms to fit user-specific problems. Coupe exploits shared memory parallelism, is written in Rust, and consists of a library and command line tools. Experimenting with different algorithms and parameters is easy.
