Markov University of Michigan, EECS Department, Ann Arbor, MI 48109-2121 1 Introduction A hypergraph is a generalization of a graph wherein edges can connect more than two ver-tices and are called hyperedges. Just as graphs naturally represent many kinds of information WebbAn efficient sparse LU factorization algorithm on popular shared memory multi-processors is presented. Pipelining parallelism is essential to achieve higher parallel efficiency and it is exploited with a left-right looking algorithm.
