Recent increases in the pin bandwidth of integratedcircuits has motivated an increase in the degree or radix of interconnection network routers. The folded-Clos network can take advantage of these high-radix routers and this paper investigates adaptive routing in such networks. We show that adaptive routing, if done properly, outperforms oblivious routing by providing lower latency, lower latency variance, and higher throughput with limited buffering. Adaptive routing is particularly useful indoi:10.1109/sc.2006.10 fatcat:n5udo3hnavbobkmlu6vrk455he
