KD-90普及型个人高性能计算机系统设计与性能优化
Design and performance optimization of a popular high performance computing system KD-90
摘要
Abstract
First of its kind and designed with 8-core Godson 3B CPU, KD-90 is a teraflops high-performance computer system. It has the characteristics of high computing density, low-power usage, low in cost and compact in size. Three parallel hierarchies, such as SMP→ CC-NUMA→Cluster, as utilized in KD-90. Both the common communication protocol and the proprietary communication protocol are integrated in the system interconnect design. Therefore, breakthroughs in the performance of the CC-NUMA cluster are achieved. The parallel programming model of the system is implemented by the combination of a general-purpose processor and vector coprocessor acceleration technology. The Linpack performance optimization works by means of architectural features and the operating system kernel is discussed in detail.关键词
