摘　　要：分析了Linux2·4内核中采用的基于蒙特卡罗方法的代码热点检测算法和实现机制,指出了其中的不足,并在此基础上提出了改进措施。As operating system is the most important system software, so the performance of OS kernel is a key factor to the whole computer system efficiency. Therefore, it is necessary to detect and optimize the codes that run most frequently, hence the codes are called hotspots. This paper analyses a mechanism based Monte Carlo method, which is used by Linux 2.4 kernel to detect hotspot of the kernel dynamically. The flaw and the remedy have also been presented herein.

关 键 词：代码热点 蒙特卡罗方法 动态检测
