Data Grid is one of the important research subjects in the field of Grid Computing. To get a high efficiency of the system, this paper proposes a set of novel multicast algorithms for Data grid, which can achieve shorter multicast delay and less resource consumptions. In contrast to previous approaches, the algorithms in this paper partition the group members into clusters in the lower layer, seeking the most plenty of date amount node as an optimal core (root) and building a shared tree within each cluster according to the algebra addition of the date amount of node and exponential to minimize the number of links used. In the upper layer, a shared tree is then constructed using our algorithms to implement the inter-cluster routing. The extended simulation results indicate that our algorithms are more suitable for Date Grid as compared with other well-known existing multicast solutions. © 2006 IEEE.
