Memory barriers c#
WebMemory barrier 简介. 程序在运行时内存实际的访问顺序和程序代码编写的访问顺序不一定一致，这就是内存乱序访问。. 内存乱序访问行为出现的理由是为了提升程序运行时的性能。. 内存乱序访问主要发生在两个阶段：. 编译时，编译器优化导致内存乱序访问 ... In computing, a memory barrier, also known as a membar, memory fence or fence instruction, is a type of barrier instruction that causes a central processing unit (CPU) or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction. This typically means that operations issued prior to the barrier are guaranteed to be performed before operations issued after the barrier.
