摘　　要：高性能计算机作为国家的战略资源,其自主性格外重要.龙芯2F是国产的高性能通用处理器,其低功耗、低成本和高集成度的特点对研制新一代高性能计算机系统具有很强的优势.KD-50-I万亿次高性能计算机采用336个龙芯2F处理器作为计算单元,使用两级全交换千兆以太网实现互连,具有高性能、低成本、低功耗和低占地面积等特点.KD-50-I的系统软件以开源软件为主,具有兼容性强、易维护、易升级、易使用等特点.在KD-50-I系统上对通信性能和BLAS数学库进行优化之后,Linpack峰值达到35.1%.High-performance computers are a national strategic resource, and it is of vital importance that they are self-designed. Loongson-2F is a general-purpose high-performance CPU designed in China. It has the advantages of low power, low cost and high integration for the design of the next generation high performance computer system. KD-50-Ⅰ tera-flops high-performance computer system is made up of 336 Loongson-2F CPUs as the computing elements, using two-level full-switched Giga-Ethernet for its interconnection. It has the advantages of high performance, low cost, low power and small occupation area etc. Most of the system software of KD-50-Ⅰ is open source software with such features as good compatibility, easy maintenance and upgrading, easy use, etc. After the optimization of communication and BLAS library, the peak benchmark performance of Linpack achieves 35.1%.
