Abstract:

With the continuous expansion of high performance computer systems to meet the increasing requirements for high performance computers, the interconnectiction network system has become the key factor that influences the performance. How to design larger-scale networks faster with lower latency and lower cost, and larger throughput based on high-radix router by making full use of the features of high-radix router is currently the main research direction. We analyze the features of the high-radix network and synthesize the torus and fat-tree topology, and put forward a new hierarchical hybrid interconnection network topology. The proposed topology has satisfactory scalability and communication capability. We finally use the network simulator NetSim to simulate and analyze its performance.
 

Key words: interconnection network, high-radix router, scalability, network performance, simulation
