Linearizability 是 sequential consistency 的子集,因为 linearizability 是在 sequential consistency 的基础上添加了一个保持没有 overlapping 的顺序的要求。 quiescent consistency 和 sequential consistency 没有包含关系,其实容易理解, 这里举出一个是 sequential consistency但是不是 quiescent concurrency 的例子。 这里是...
何为组合: A correctness property is compositional if, whenever each object in the system satisfies , the system as a whole satisfies .在当前上下文中间,not limit concurrency 其实只是说当前历史是符合某种一致性,比如顺序一致性,并且含有pending的inv,那么当其获得 response 的时候,可以保...
前面讨论过 sequential consistency,这两者其实前者要求更高,及 sequential consistency 要求存在的序同时也保持全局、外部的顺序的时候为 linearizability。很自然这个定义上来看 atomicity 更难以并行,其好处是之一我们可以从这个序的要求上看出来,之二是它是是 compositional 的,意味着可以将两个 linearizable 的实现组合获...
Linearizability and Sequential Consistency Sequential Consistency A data store issequentially consistentwhen the result of any execution is the same as if the (read and write)operations by all processes on the data store were executed in some sequentialorder and the operations of each individual proces...

We establish sequential consistency, linearizability, and (FCFS) as a strict hierarchy of implementation conditions, meaning that there are problems solvable under one requirement, but not under a stronger one. We p r e s e n t the implementations of a regular queue and of a starvation-free ...
