Once again: Connected Components on a CREW-PRAM
Kai Werther [Download PostScript] [Download PDF] We present an algorithm to compute the connected components of a graph in parallel time O(log|V| log log|V|) on a CREW-PRAM with a linear number of processors. This closes the gap to the best known (and trivial) lower bound of Ω(log|V|) from previously O(log1/2|V|) to O(log log|V|). |
