Abstract

The performances of multiprocessor systems mainly rely on the processor clock speed and the memory latency. As the processors speed up rapidly, the memory latency becomes a major performance bottleneck in multiprocessor systems. In this paper, we propose a dual-link interconnection topology and its effective routing scheme to reduce the remote memory latency on the interconnection network. It can be applied at a same implementation cost as traditional bi-directional ring systems. We compare the performance of the proposed system to that of the traditional bi-directional ring-based system and toroidal mesh-based system. By simulations, it is shown that the proposed system outperforms the traditional bi-directional ring-based system by 42∼101 % and excels the toroidal mesh-based system by 4∼14%.
