CC-NUMA多处理机操作系统设计

The OS Design of a CC-NUMA Multiprocessor System

多处理机系统是实现并行处理的高效低价的选择,要发挥多处理机系统的性能必须要有相应的软件支撑,这中间最为重要的就是操作系统.CC-NUMA结构的多处理机系统以其紧耦合性和良好的可扩展性而得到了日益广泛的应用,本文讨论了CC-NUMA技术的特点,并重点论述了CC-NUMA结构的多处理机系统S1000的操作系统设计及其扩展.

Multiprocessor system is a high performance and low value choice to implement parallel process. In order to develop the performance of the multiprocessor systems, the support software is essential, of which the operating system is the most important. The cache coherent non uniform memory access(CC\|NUMA) multiprocessor system is increasingly used because it is close coupling and scalable. In the paper, firstly we discuss the architecture of the CC NUMA multiprocessor system. Secondly we emphatically analyze the design of S1000's operating system as a CC NUMA example. Finally we recount the extension of the S1000.
