Abstract

In this paper, we propose an efficient algorithm for parallel prefix computation in recursive dual-net, a newly proposed network The recursive dual-net RDNk(B) for k0 has ${(2n_0)^{2^k}/2}$ nodes and d0+k links per node, where n0 and d0 are the number of nodes and the node-degree of the base network B, respectively Assume that each node holds one data item, the communication and computation time complexities of the algorithm for parallel prefix computation in RDNk(B), k0, are ${2^{k+1}-2+2^k*T_{comm}(0)}$ and ${2^{k+1}-2+2^k*T_{comp}(0)}$, respectively, where Tcomm(0) and Tcomp(0) are the communication and computation time complexities of the algorithm for parallel prefix computation in the base network B, respectively.
