SpeedSiteRank: PageRank algorithm distributed in websites

A global and centralized classification of web pages requires a fairly high computation cost and therefore does not favor a regular updating of the index database. To overcome this problem, we propose in this article an asynchronous parallel algorithm, called SpeedSiteRank, capable of calculating the PageRank vector by site. The results of tests carried out on a cluster made up of 10 bi-opteron nodes demonstrated the efficiency of our algorithm.
