之前main thread 执行的 load(SeqCst) 仅是一个 acquire operation, 并不会与 worker1 任何操作形成 synchronizes-with 关系. 改成 fetch_add(0, SeqCst) 之后同时是一个 Acquire/Release operation, 与 worker1 的 self.state.fetch_sub(dec, SeqCst) 这个 Acquire/Release operation 形成了 synchronizes-wit...

__sync_fetch_and_add系列一共有十二个函数，有加/减/与/或/异或/等函数的原子性操作函数,__sync_fetch_and_add,顾名思义，先fetch，然后自加，返回的是自加以前的值。以count = 4为例，调用__sync_fetch_and_add(&count,1)之后，返回值是4，然后，count变成了5.简单验证代码如下sync_fetch_add.c:#...
A Wait-free Queue as Fast as Fetch-and-Add的设计同样是基于 FAA指令,但不同的是它没有基于循环数组,它把数组组织为可持续增长的单链表,同时每个数组配置一个代表偏移的Id用于快速的定位。它非常完美的同时做到了linearizability、wait-free,并且实际使用中非常快。但是它的实现相当复杂,非常精细地定义了代表入队...
