The instructions of a program are executed in source code order. There is a global order of all operations on all threads. Sequential Consistency提供了非常强的约束: 程序的执行是按照代码的"书写顺序"执行,也就是没有编译器等造成的优化乱序了; 所有线程的代码有一个总的确定的执行的顺序。

线程是CPU最小的执行和调度单位。多个线程共享进程的资源。 创建线程比创建进程更快,开销更小。 创建线程的方法:pthread_create、std::thread。 pthread_create:传入的线程函数只有一个参数。 std::thread:传入的线程函数可以有任意数量的参数。 因为,thread类的构造函数是一个可变参数模板,可接收任意数目的参数,其中...
