Design of tera-flops high-performance computer KD-50-I based on Loongson-2F CPU
Huiming Li · 2008
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%.
