超线程 [英] Hyper-threading
问题描述
我的应用程序使用多线程，是一种AI模拟或
ALife。这很好用，但我想知道是否以及如何使用？＃b $ b超线程在C＃中？
感谢任何提示，Francois

.NET线程映射在OS线程上，因此操作系统将安排这些
线程，因此如果启用了超线程，则线程将利用这一点来支付
。

感谢您的回答。
好吧，那么超线程只是一个引人注目的问题：只要我有一个
超线程CPU和一个带有威胁的应用程序我免费获得超线程
技术，对吗？

你将拥有正确的HAL，因此可能无法充分利用多CPU的优势。一旦启用HT，您将需要安装正确的
。
在设备管理器中展开计算机节点，如果您看到多处理器
PC（或指示超过一个CPU）你很好。但是，如果您看到单处理器PC，您将需要转到它的属性并更新
驱动程序。手动选择驱动程序进行安装。您将需要使用与您拥有的单处理器驱动程序匹配的多处理器驱动程序，在我的
情况下它是一个ACPI驱动程序。请确保你没有选错。
过去我做了一些实验，发现我可以在我的机器上从Multi到
Uni，但是无法回去多。希望它是
，因为我从一个切换到另一个。如果您无法升级驱动程序以获得
的多重驱动，则需要在启用HT的情况下重新安装Windows。
如果一切顺利，您应该在性能中看到两个CPU窗口任务经理的标签。

My application uses multiple-threads and is a kind of AI simulation or
ALife. This works fine but I was wondering if and how one can make use
of hyper-threading in C#?
Thanks for any hint, Francois

.NET threads are mapped on OS threads, so the OS will schedule these
threads and therefore if hyperthreading is enabled, the threads will
take advantage of that.

Just a silly question: How do I enable hyperthreading? Is this an option in
the C# project or an option I have to set somewhere in the control panels or
is this a build in feature of the processor?

Thanks for the answers.
Well, then hyperthreading is just an eye catcher: As long I have a
hyperthreading CPU and an application with threats I get the Hyperthreading
technology for free, am I right?

news:ed*************@TK2MSFTNGP12.phx.gbl...However, if it wasn''t enabled when you installed windows I don''t believe you will have the correct HAL and therefore may not be able to take full
advantage of the multi CPU''s. You will need to install the correct one once you enable HT.
In Device manager you expand the Computer node, if you see multiprocessor PC (or something that indicates more than one CPU) you are fine. However, if
you see Uniprocessor PC, you''ll want to go to it''s properties and update
driver. Choose the driver manually to install. You will want to use the
Multiprocessor driver that matches the uniprocessor driver you have, in my
case it is an ACPI driver. Be sure you don''t select the wrong one.
In the past I did some experimenting and found I could go from Multi to Uni in my machine, but was unable to go back to multi. Hopefully it was because I switched from one to the other. If you can''t upgrade the driver to get the multi, you will need to reinstall windows with the HT enabled.
If all goes well you should see two CPU windows in the performance tab of
the Task Manager.
