Abstract

The torus network is one of the most popular interconnection topologies for massively parallel computing systems. In this paper, we mainly consider the p-panconnectivity of n-dimensional torus networks with faulty elements (vertices and/or edges). A graph G is said to be p-panconnected if for each pair of distinct vertices u,v@?V(G), there exists a (u,v)-path of each length ranging from p to |V(G)|-1. A graph G is m-fault p-panconnected if G-F is still p-panconnected for any F@?V(G)@?E(G) with |F|@?m. By using an introduction argument, we prove that the n-dimensional torus T"2"k"""1"+"1","2"k"""2"+"1","...","2"k"""n"+"1 is @?"i"="1^nk"i-panconnected and (2n-3)-fault [@?"i"="1^n(k"i+1)-1]-panconnected.
