Abstract:

As the scale of high performance network increases, the design of high-radix router architecture is becoming a focus and a hotspot in the field of high performance computing. Using high-radix routers, the network can gain lower transmission latency, lower cost of network construction and lower power, and improve network reliability simultaneously. Over the past decade, high-radix routers have developed quickly. We present related research on high-radix routers and predict future development trends, mainly introducing the structured design represented by YARC and the “network within a network” approach. Our future study focuses on solving a number of problems such as buffer and arbitration, and we use some new techniques such as optical interconnection to design better architectures.Key words:high performance computing;high-radix router;structured design;optical interconnection
