Abstract

More recently, multicast communication has been included in multicomputer systems. Multicast communication refers to the delivery of the same message from a source node to an arbitrary number of destination nodes. The performance of multicomputers is highly dependent on the message routing scheme and the communication mechanism. Wormhole routing is the most promising switching technique used in the new generation multicomputers. The authors propose a multicast wormhole routing algorithm for 2D-torus multicomputers. The multicast routing algorithm is based on a path-like routing scheme and offers a deadlock-free routing. Comparing with the 2D-mesh multicomputers, the authors simulation show that the multipath routing algorithm for 2D-torus multicomputers can reduce the communication traffic and the maximum distance in multicast communication
