Parallel Computation on Interval Graphs: Algorithms and Experiments

Abstract : This paper describes efficient coarse-grained parallel algorithms and implementations for a suite of interval graph problems. Included are algorithms requiring only a constant number of communication rounds for connected components, maximum weighted clique, and breadth-first-search and depth-first-search trees, as well as O(log p) communication rounds algorithms for optimization problems such as minimum interval covering, maximum independent set and minimum dominating set, where p is the number of processors in the parallel system. Implementations of these algorithms are evaluated on parallel clusters, using both Fast Ethernet and Myrinet interconnection networks, and on a CRAY T3E parallel multicomputer, with extensive experimental results being presented and analyzed.
