Shared memory multilevel graph partitioning
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. Webb1 jan. 2024 · Jafari et al.
