Finding strongly connected components in distributed graphs

McLendon, William; Hendrickson, Bruce A.; Plimpton, Steven J.; Rauchwerger, Lawrence

The traditional, serial, algorithm for finding the strongly connected components in a graph is based on depth first search and has complexity which is linear in the size of the graph. Depth first search is difficult to parallelize, which creates a need for a different parallel algorithm for this problem. We describe the implementation of a recently proposed parallel algorithm that finds strongly connected components in distributed graphs, and discuss how it is used in a radiation transport solver. © 2005 Elsevier Inc.
