Abstract

We examine existing parallel algorithms for detection of strongly connected components and discuss their applicability to the case when the graph to be decomposed is given implicitly. In particular, we list individual techniques that parallel algorithms for SCC detection are assembled from and show how to assemble a new more efficient algorithm for solving the problem. In the paper we also report on a preliminary experimental study we did to evaluate the new algorithm.
