网上有人借用std::atomic实现的一套无锁队列,其内部实现参考了boost::lockfree::queue的设计思路,可以适用于多个消费者多个生产者线程。 A High Performance Lock Free Ring Queue http://www.codeproject.com/Tips/754393/A-High-Performance-Lock-Free-Ring-Queue 下面代码我在原文基础上做了修改:最新的编译器已...

什么是lock-free? lock-free没有锁同步的问题,所有线程无阻碍的执行原子指令,而不是等待。 比如一个线程读atomic类型变量,一个线程写atomic变量,它们没有任何等待,硬件原子指令确保不会出现数据不一致,写入数据不会出现半完成,读取数据也不会读一半。 那到底什么是lock-free?
