Abstract

In this paper, a new interconnection network called the incomplete crossed hypercube is proposed for connecting processors of parallel computing systems. The incomplete crossed hypercube architecture denoted by CI n驴m n is made by combining two complete crossed hypercubes CQ n and CQ n驴m for 1驴m驴n. Several topological properties of CI n驴m n are analyzed. In particular, accurate mean internode distance formulas of both CQ n and CI n驴m n are given. Compared with the incomplete enhanced hypercube EI n驴m n , CI n驴m n has shorter mean internode distance for large n. An optimal routing algorithm for CI n驴m n is also described which guarantees the generation of a shortest path from a node to another in CI n驴m n .
