Abstract

Crossed cubes are an important class of variants of hypercubes as interconnection topologies in parallel computing. In this paper, we study the embedding of a mesh of trees in the crossed cube. Let n be a multiple of 4 and N=2^(^n^-^2^)^/^2. We prove that an NxN mesh of trees (containing 3N^2-2N nodes) can be embedded in an n-dimensional crossed cube (containing 4N^2 nodes) with dilation 1 and expansion about 4/3. This result shows that crossed cubes are promising interconnection networks since mesh of trees enables fast parallel computation.
