An optimal fault-tolerant broadcasting algorithm for a cube-connected cycles multiprocessor

The author develops a novel broadcasting algorithm in cube-connected-cycles (CCC) multiprocessors using a binomial tree. The initiating processor takes (h-1/2)+s (1+(h-1/2)) steps to broadcast the message to all other processors. The proposed broadcasting algorithm is a procedure by which a processor can pass a message to all other processors in the network nonredundantly: it is extremely important for diagnosis of the network, distribution agreement, or clock synchronization. The author also describes an optimal fault-tolerant broadcasting algorithm in the CCC which tolerates s-1 processors or s-1 ring failures. The algorithm takes 1+2* ((h-1/2))+s(1+(h-1/2)) steps to broadcast the message to all other processors in optimal fault-tolerant broadcasting.<>
