| 摘 要： | 核心线程是微内核操作系统Ｍａｃｈ调度的基本单位，它较好地支持了细粒度的并行计算，但核心线程在支持用户并发模型、双并发模型上还有许多缺点。用户级线程是在核心线程的支持下建立的更高层次的用户调度单位，能较好地支持用户程序的并发执行。本文重点介绍在核心线程支持下的用户级线程—ＣＴｈｒｅａｄ的实现方案

| Abstract: | Kernel thread is the basic scheduling unit in the microkernel operating system Mach.It supports fine grained parallel computing,but microkernel thread has many shortcomings in supporting user concurrence models and double concurrence models.User level thread is the higher level user scheduling unit supported by kernel thread,it supports concurrent execution of user programs.This paper focuses on the implementation design of CThread,a user level thread supported by kernel thread. |

| Keywords: | user level thread kernel thread microkernel virtual processor. |
