In this paper, we present a strongly fault-tolerant design for the k-ary n-cube multiprocessor and examine its reconfigurability. Our design augments the k-ary n-cube with k j n spare nodes; each set of jn regular nodes is connected to a spare node and the spare nodes are interconnected as a k j -ary n-cube. Our approach utilizes the circuit-switched capabilities of the communication modules of the spare nodes to tolerate a large number of faulty nodes and faulty links without any performance degradation. Both theoretical and simulation results are presented.
