Direct interconnection network (DIN) has gained more and more attention when designing the switching fabric in the terabit routers. Various congestion control mechanisms are proposed for DIN when it is employed in the parallel computer systems. However, th...
 
A New Routing Method to Tolerate both Convex and Concave
Found in: Parallel and Distributed Computing Applications and Technologies, International Conference on
By Huaxi Gu, Zengji Liu, Guochang Kang, Hong Shen
Issue Date:December 2005
pp. 714-719
To make the exiting fault routing algorithms tolerate concave fault regions without disabling any healthy nodes, the concept of hole is proposed in this paper. A hole consists of healthy nodes in the concave parts and neighborhood of a given concave fault ...
 
Analyzing Packet-Level Routing in Data Centers
Found in: 2013 IEEE International Conference on Dependable, Autonomic and Secure Computing (DASC)
By Ruoyan Liu,Huaxi Gu,Yawen Chen,Haibo Zhang
Issue Date:December 2013
pp. 648-652
Data centers host diverse applications with stringent QoS requirements. The key issue is to eliminate network congestions which severely degrade application performance. One effective solution is to balance the traffic load in the datacenter regular topolo...
 
ODOR: a microresonator-based high-performance low-cost router for optical networks-on-Chip
Found in: Proceedings of the 6th IEEE/ACM/IFIP international conference on Hardware/Software codesign and system synthesis (CODES/ISSS '08)
By Huaxi Gu, Jiang Xu, Zheng Wang
Issue Date:October 2008
pp. 1001-1001
The performance of system-on-chip is determined not only by the performance of its functional units, but also by how efficiently they cooperate with one another. It is the on-chip communication architecture which determines the cooperation efficiency. Netw...
