有的时候,解释器指的是Python Interpreter,也就是你在命令行交互界面上输入python的时候。有的时候人们或多或少的交换使用python和python解释器来表明python从执行到结束的的过程。在本章中,解释器有更加确切的意思:python执行过程中的最后一步。 在解释器完成之前,python还有三个步骤需要执行:词法分析,语法解释,编译。最...
用户级线程执行系统调用指令时将导致其所属进程被中断,而内核支持线程执行系统调用指令时,只导致该线程被中断。 在只有用户级线程的系统内,CPU调度还是以进程为单位,处于运行状态的进程中的多个线程,由用户程序控制线程的轮换运行;在有内核支持线程的系统内,CPU调度则以线程为单位,由OS的线程调度程序负责线程的调度。
