JET: MULTILEVEL GRAPH PARTITIONING ON GRAPHICS PROCESSING UNITS

The multilevel heuristic is the dominant strategy for high-quality sequential and parallel graph partitioning. Partition refnement is a key step of multilevel graph partitioning. In this work, we present Jet, a new parallel algorithm for partition refnement specifcally designed for graphics processing units (GPUs). We combine Jet with GPU-aware coarsening to develop a k-way graph partitioner, the Jet partitioner. The new partitioner achieves superior quality when compared to state-of-the-art shared memory partitioners on a large collection of test graphs.
