Abstract: Leiden algorithm has demonstrated superior efficacy compared to traditional Louvain algorithms in the field of community detection. However, parallelizing the Leiden algorithm while imposing community size limitations brings significant challenges in big data processing scenarios. We present ParLeiden, a pioneering parallel Leiden strategy designed for distributed environments. By thread locks and efficient buffers, we effectively resolve community joining conflicts and reduce communication overheads. We can run Leiden algorithm on large-scale graphs and achieve performance speedup on up to 9.8 times than baselines.
