Lock-free programming is a technique that allow concurrent updates of shared data structures without the need to perform costly synchronization between threads. This method ensures that no threads block for arbitrarily long times, and it guarantee progress for some threads when there are multiple threa...

Lock-Free 编程是什么? 当谈及 Lock-Free 编程时,我们常将其概念与 Mutex 或 Lock 联系在一起,描述要在编程中尽量少使用这些锁结构,降低线程间互相阻塞的机会,以提高应用程序的性能。类同的概念还有 "Lockless" 和 "Non-Blocking" 等。实际上,这样的描述只涵盖了Lock-Free 编程的一部分内容。本质上说,Lock-...

垃圾回收机制与无锁化编程(Garbage Collection and Lock-Free Programming) 垃圾回收机制(GC)对大部分开发者来说应该不陌生,特别是Java开发者或多或少都跟GC打过交道。 GC的优点是实现对堆上分配的内存动态回收,避免内存泄漏。但是GC的缺点是对性能有一定影响,特别是stop the world问题, 而且GC什么时候回收内存是...
大家好,又见面了,我是你们的朋友全栈君。 涉及到并行/并发计算时,通常都会想到加锁,加锁可以保护共享的数据,不过也会存在一些问题: 1. 由于临界区无法并发运行,进入临界区就需要等待,加锁使得效率的降低。多核CPU也不能发挥全部马力 2. 在复杂的情况下,很容易造成死锁,并发进程、线程之间无止境的互相等待。
3. Talk about Lock-Free Programming Practices in iLogtail To solve the problems caused by locks, lock-free programming provides an alternative method. Lock-free programming does not rely on traditional lock synchronization. It uses atomic operations to ensure that multiple threads can safely access ...
