C＃中的超级Thriding [英] Hyper Thriding in C#

问题描述

我创建新线程如下：

线程mThread =新线程（新ThreadStart（m_ClassThread.Go））;

如何选择运行此线程的位置？

在我的系统中，我有2个进程设备，（CPU0和CPU1），我想要创建3

这些线程的线程2在CPU0中运行，最后一个在CPU1中，是否有任何方式来控制线程执行？
如何在特定的CPU中请求执行特定的

线程？

使用WMI我可以在我的系统中接收CPUs deviceID。但我不知道

如何控制....

解决方案

你可以设置线程亲和力，排序。运行时不提供任何

支持，但您可以使用Windows SetThreadAffinity来确定

线程执行的位置。但是，运行时不会让一个线程确定一个线程将是一个文字系统线程，因此你无法安全地在所有

版本中执行此操作。在1.1中它应该是安全的，我不知道2.0。

我找不到有关SetThreadAffinity的完整信息，你可以通过一个好的

这个链接？，这不是C＃功能我是否正确？

您需要通过PInvoke访问它。如果您需要它，请链接到下面的PInvoke教程

I create new thread as following:
Thread mThread = new Thread(new ThreadStart(m_ClassThread.Go));
How can I choose where to run this thread ?
In my system I have 2 Process devices ,(CPU0 and CPU1) , I want to create 3
Thread 2 of those thread to run in CPU0 and the last one in CPU1 , is there
any way to control threads execution ? How can I ask for execution specific
thread in specific CPU?
"Using WMI I can receive the CPUs deviceID in my system". But I don''t know
how to control....

You can set the thread affinity, sort of. The runtime doesn''t offer any
support but you can use the windows SetThreadAffinity to determine where the
thread executes. However, the runtime makes no gaurentee that a thread will
always be a literal system thread, thus you cannot safely do this across all
versions. In 1.1 it should be safe, I don''t know about 2.0.

I can''t find usfull information about SetThreadAffinity, can you past a good
link for this ?, It''s not C# function am I correct ?
