Evaluation of Three Quads Using Matrix Transpose.

For medium scale commodity cluster, a high cost performance interconnection network named Three Quads was proposed. Topological features of Three Quads include 1) diameter of two, 2) embed-ability of 3D torus and many well-known topologies, and 3) fault tolerance and path diversity. All the hardware components of Three Quads are essentially small-scale and off-the-shelf commodity hardware to achieve superior cost performance. In this paper, the performance of the Three Quads is evaluated using a matrix transpose application and results show that the Three Quads gives appealing performance comparable to a large scale and expensive enterprise switch fabric.
