互连网络路由器是MPP系统的关键部件，其性能优劣直接影响系统性能．本文在mesh结构上，针对完全自适应路由算法实现难度较大的问题，在性能、代价和实现复杂性上进行合理折衷，给出了一个代价低、自适应性强的完全自适应路由算法LCFAA，对传统的虫孔路由切换技术进行改进，提出了弹性虫孔路由切换技术（elasticwormhole），并采用基于虚通道的综合流控策略，设计了一个简洁高效的完全自适应路由器LFR，其逻辑在XilinxXAry的CADI具上进行了模拟验证
Interconnecting network router is a key component of MPP system, the performance of its direct impact on system performance. In the mesh structure, aiming at the more difficult problem of fully adaptive routing algorithm, this paper makes a reasonable compromise on the performance, cost and complexity of implementation, and presents a low cost and adaptive adaptive routing algorithm LCFAA , This paper improves the traditional wormhole routing switch technology and proposes an elastic wormhole routing switch technology (elasticwormhole). Based on the virtual channel comprehensive flow control strategy, a simple and efficient fully adaptive router LFR is designed, whose logic is Simulation of XilinxXAry’s CADI tools
