[Abstract]:In the development of high performance computer system, the bottleneck of data transmission between processors is becoming more and more prominent due to the increasing speed of multi-core processors. High-frequency transmission technology can improve the transmission performance, but also reduce the inherent reliability of the component level; At the same time, with the expansion of the scale of high performance computer system and the increasing of the components of high speed interconnection network, the inherent reliability of system level is further reduced. It is an important task to improve the availability of high-speed interconnection networks by using efficient and concise fault-tolerant techniques. Since the successful development of the TH-1A high performance computer system interconnection network, the research group has studied several key technologies of the new generation high speed interconnection network in view of the further development demand of the high performance system and the development trend at home and abroad. Based on the above background, this paper focuses on the fault-tolerant technology of high-speed interconnection network. The main work is as follows: 1. Taking the current mainstream high-performance computer system as an example, the topology of the interconnection network, routing algorithm, The flow control strategy and other technologies are analyzed, and the related fault tolerant techniques used in these systems are summarized. 2. For the router design of the new generation high-speed interconnection network, a micro-architecture design which can support adaptive routing strategy is proposed, which has the characteristics of supporting various topologies and routing algorithms. 3. The network structure design of the new generation high-speed interconnection network is aimed at the topology structure of the high-dimensional interconnect network, which is interlinked by 3D-Torus and all connected networks. Two adaptive fault-tolerant routing algorithms based on channel sorting and escape channel are proposed. 4. The InfiniBand network management protocol is analyzed, and the related algorithms and network management protocols for realizing topology discovery, routing calculation, path distribution in a new generation of high-speed interconnection networks are studied. 5. Based on the OMNeT platform, the corresponding router structure, interconnection network topology, fault-tolerant routing algorithm and subnet management protocol are implemented, and the behavior level simulation and performance evaluation of the system are carried out.
