等待IO的线程是否也阻塞了内核?(Does a thread waiting on IO also block a core?)

在计算的同步/阻塞模型中,我们通常会说等待IO任务完成时,一个执行线程将等待(被阻塞 )。

我的问题是,这通常会导致执行线程的CPU内核处于空闲状态,或者等待IO的线程通常会被上下文切换并处于等待状态,直到IO准备好被处理?


In the synchronous/blocking model of computation we usually say that a thread of execution will wait (be blocked) while it waits for an IO task to complete.

My question is simply will this usually cause the CPU core executing the thread to be idle, or will a thread waiting on IO usually be context switched out and put into a waiting state until the IO is ready to be processed?

最满意答案

我想我已经解决了。 每当我使用ReSharper运行我的silverlight单元测试时,都会发现这个问题。 但是,如果我使用内置的运行Web应用程序进行silverlight测试,则异常消失了


I think i've solved it. the issue only is found whenever I use ReSharper for running my silverlight unit tests. But if i use the built in running web app for the silverlight tests, the exception is gone
