Shared memory multilevel graph partitioning

http://algo2.iti.kit.edu/seemaier/deep_mgp/ WebbMultilevel algorithms are a successful class of optimization techniques which addresses the mesh partitioning problem. They usually combine a graph contraction algorithm together with a local optimization method which refines the partition at each graph level.

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.

As with graphs, partitioning a hypergraph also means to find an assignment of nodes to different blocks of (mostly) equal size. edgewood nursing home raytown mo

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.
