| 摘 要： | 随着硬件技术的飞速发展，双核乃至多核的计算机的普及，操作系统向多核平台移植的需要也越来越迫切。详细分析操作系统在向多CPU支持的平台移植时可能遇见的伪共享问题及优先级错置问题的产生原因，针对不同情况提出了按规范修改代码、增加内核调度监控线程及将特定程序绑定在单CPU运行等不同对策，并给出了实现方法。

| Abstract: | With the fast development of hardware and computers with mutli-core technology,the operating system is transplanted to mutli-core environment urgently.The false sharing and thread priority questions maybe found within the migrate process are analysed,for different conditions,different methods such as modifying the source code,adding a kernel thread to control priority and running special program on single CPU are proposed. |

| Keywords: | mutli-core environment false sharing thread priority operating system |
