中文摘要：
国产万亿次高性能计算机KD-50-I具有低功耗、低面积和高集成度等特点，对未来研制国产千万亿次计算机系统及提高其自主创新性具有示范作用．高性能计算机KD-50-I达到实用化，必须要有与之相配套的高效通信性能．针对万亿次机KD-50-I节点间拓扑固定和层次简单的网络结构特点，采用简化的LBP通信模型分析和优化了点对点通信和全局通信，对KD-50-I国产高性能机的推广普及具有重要的意义．
英文摘要：
Tera-Flops High-Performance Computer has the advantages of low power, small occupation area and high integration, and it is the model for the design of the next generation high-productivity high performance computer system. Efficient communication performance is necessary for the practicality of KD-50-I. As for the fixed topology and simple network structures of KD-50-I, LBP communication model is applied to analysis and optimize compunction. Optimizing point-to-point and collective communication is significant for the popularization of Tera-Flops High-Performance Computer KD-50-I made in China.
