N2 - Hierarchical clustering has many advantages over traditional clustering algorithms like k-means, but it suffers from higher computational costs and a less obvious parallel structure. Thus, in order to scale this technique up to larger datasets, we present SHRINK, a novel shared-memory algorithm for single-linkage hierarchical clustering based on merging the solutions from overlapping sub-problems. In our experiments, we find that SHRINK provides a speedup of 18-20 on 36 cores on both real and synthetic datasets of up to 250,000 points. Source code for SHRINK is available for download on our website, http://cucis.ece.northwestern.edu.
