Multilevel hypergraph partitioning

Web7 ian. 2024 · Abstract A directed acyclic hypergraph is a generalized concept of a directed acyclic graph, where each hyperedge can contain an arbitrary number of tails and heads. Directed hypergraphs can be used to model data flow and execution dependencies in streaming applications. Thus, hypergraph partitioning algorithms can be used to obtain … WebBoth shmetis and hmetis can also compute a k-way partitioning when certain vertices of the hypergraph have pre-assigned partitions (i.e., there are at most k sets of vertices each fixed to a particular partition). The third program (khmetis) computes a k-way partitioningusing multilevel k-way partitioning[8]. This is a new
