Webb1.3.1 Graph Partitioning We develop and compare multiple approaches for parallelizing each of the three phases of multilevel graph partitioning: coarsening, initial partitioning, and uncoarsening using shared memory [22]. We develop and study new aggregation schemes which allow for the coarsening phase to achieve strong parallel scalability. WebbKaMinPar is a shared-memory parallel tool to heuristically solve the graph partitioning problem: divide a graph into k disjoint blocks of roughly equal weight while minimizing …

Webb12 sep. 2024 · This streaming algorithm serves multiple purposes in the partitioning process: a clustering algorithm in the coarsening, an effective algorithm for the initial partitioning, and a fast refinement algorithm in the uncoarsening. Its simple nature also lends itself easily for parallelization. Webb28 jan. 2024 · These algorithms can partition huge graphs quickly with little memory, but they produce partitions with low quality. On the other hand, there are offline (shared-memory) multilevel algorithms that produce partitions with high quality but also need a machine with enough memory to partition a network.
