Abstract:

With the expansion of highperformance interconnect network,how to improve the performance and reduce the physical overhead of the system through the design of interconnection network topology has become crucial in system design.The traditional topology,which can be divided into direct and indirect networks,does not keep a perfect balance between network performance and the physical overhead when the network size increases.In 2012,Roberto proposed a new family of hybrid topology,which combines the features of the direct network and indirect network and makes a balance between network performance and physical overhead. Based on these,the new family of topology can be optimized to be hybrid topology which owns more than one indirect networks.Theory analysis and simulation of both the new family of hybrid topology and the traditional topologies show that the optimized new family of hybrid topology can improve network performance while reducing physical overhead.
