互连网络的容错能力是并行计算中的一个关键问题,而d进制n维方(超方的一般形式)在计算机的互连网络中已得到广泛的应用。本文考虑有节点故障的d进制n维方的容错性。F是d进制n维方Qn(d) 中的错误点集(n≥3), 且|F|≤n-2,证明了Qn(d)的每个无故障的边和无故障的点存在于长从4到dn-2|F|的无故障偶圈中。而且,当d是奇数时,Qn(d)的每个无故障的边和无故障的点存在于长为dn-2|F|的无故障圈中。 |

Abstract: |
The d-ary n-dimensional cube (the general form of hypercube) has been widely used as the interconnection network in parallel computers.The fault-tolerant capacity of an interconnection network is a critical issue in parallel computing.In this article, we consider the fault-tolerant capacity of the d-ary n-dimensional cube.Let F be a set of faulty vertices in Qn(d) (n≥3) with |F|≤n-2, we prove that every fault-free edge and fault-free vertex (node) of Qn(d) lies on a fault-free cycle of every even length from 4 to dn-2|F|.Moreover, if d is an odd number, every fault-free edge and fault-free vertex (node) of Qn(d) lies on a fault-free cycle of length dn-2|F|. |
