摘要

研究了通过增加虫洞路由算法的自适应来改善环面互连网络中的消息延迟和网络利用率。针对统一、热点和局部流量模式,将最近提出的部分自适应算法和四种新的全自适应路由算法与著名的e-cube算法进行了比较。我们的模拟表明,对于所有三种流量模式,部分自适应的北后算法比非自适应的e-cube路由算法性能更差,这会导致网络中的流量不平衡。我们研究的另一个结果是,完全适应并不一定会提高表现。特别是,一种经常讨论的全自适应路由算法,它在k-ary n-cube的每个物理通道中使用2n个虚拟通道,对于统一和热点流量模式的性能比e-cube差。其他三种完全自适应算法(根据行进距离优先处理消息)在所有三种流量模式下的表现都比e-cube和部分自适应算法好得多。这项研究的结论之一是,适应性,完全或部分,并不一定是虫洞路由的好处。

A Comparison Of Adaptive Wormhole Routing Algorithms
Improvement of message latency and network utilization in torus interconnection networks by increasing adaptivity in wormhole routing algorithms is studied. A recently proposed partially adaptive algorithm and four new fully-adaptive routing algorithms are compared with the well-known e-cube algorithm for uniform, hotspot, and local traffic patterns. Our simulations indicate that the partially adaptive north-last algorithm, which causes unbalanced traffic in the network, performs worse than the nonadaptive e-cube routing algorithm for all three traffic patterns. Another result of our study is that the performance does not necessarily improve with full-adaptivity. In particular, a commonly discussed fully-adaptive routing algorithm, which uses 2n virtual channels per physical channel of a k-ary n-cube, performs worse than e-cube for uniform and hotspot traffic patterns. The other three fully-adaptive algorithms, which give priority to messages based on distances traveled, perform much better than the e-cube and partially-adaptive algorithms for all three traffic patterns. One of the conclusions of this study is that adaptivity, full or partial, is not necessarily a benefit in wormhole routing.
