,信号量等,这些技术已经基本可以解决99%的问题,可以称为基于锁(lock-based)的多线程编程技术。 既然有基于锁的,当然应该也有无锁的多线程编程技术(lock-free)。 Lock-free programming is a technique that allow concurrent updates of shared data structures without the need to perform costly synchronization ...
理解lock-free编程的关键在于，它不再使线程等待锁的释放。线程独立更新数据结构的局部副本，并通过CAS（Compare-And-Swap）操作原子性地更新共享结构。这样，程序可以避免长时间的等待，从而提高整体性能。在实际编程中，lock-free技术通过原子类型和原子操作实现。C/C++11标准库提供了原子类型、原子操作和内...
Michael-Scott非阻塞队列(lock-free)算法的C实现 Michael-Scott非阻塞队列算法,即MS-queue算法,是1 9 9 6 年由Maged . M .Michael and M. L. Scott提出的,是最为经典的并发FIFO队列上的算法,目前很多对并发FIFO队列的研究都是基于这个算法来加以改进的。在共享内存的多核处理器上,这种基于Compare-and-swap(...
