强制C＃应用程序在具有多核处理器的PC中使用单核 [英] Force C# application to use a single core in a PC with a multicore processor

问题描述

大家好，这个问题似乎很奇怪，但是我在C＃应用程序中使用的是Haptek People Putty播放器，而且我在论坛上看到有人说它在多核处理器上不能很好地工作。我的应用程序在Core 2 Duo笔记本电脑上可以很好地运行，但是当我尝试在Quad Core台式机上运行它时，它会滞后很多。我当时想为自己进行调查，在这种情况下，我将不得不强制我的应用程序在单个内核上运行。在C＃中有可能吗？谢谢！

Hi guys this question might seem weird, but I'm using the Haptek People Putty player for my C# application and I've seen people say in the forums that it doesn't work well with a multicore processor. My application runs well on my Core 2 Duo laptop but it lags a lot when I try running it on a Quad Core desktop. I was thinking of investigating this for myself and in that case, I would have to force my application to run on a single core. Is that possible in C#? Thanks!

推荐答案

其中 Process 变量 proc 保存您关心的进程（正在运行的Process的 Process.GetCurrentProcess（），从 GetProcesses（）获取它或 GetProcessesByName（）等用于另一个进程，然后：

Where a Process variable proc holds the process you care about (Process.GetCurrentProcess() for the running Process, obtaining it from GetProcesses() or GetProcessesByName() etc. for another process. Then:

foreach(ProcessThread pt in proc.Threads)
{
   pt.IdealProcessor = 0;
   pt.ProcessorAffinity = (IntPtr)1;
}

IdealProcessor是单个内核的从零开始的标识。ProcessorAffinity是一个位掩码，因此1允许内核为零，

IdealProcessor is a zero-based identity of a single core. ProcessorAffinity is a bitmask, so 1 allows core zero, 2 allows core one, 3 allows cores zero and one, 4 allows core two, and so on.

我会对此进行彻底的测试。非常强大，这实际上会损害您的性能，从而降低使用不同内核的能力，毕竟这通常是一个优势。

I would test this thoroughly. Chances are very strong that this will actually damage your performance, in reducing the ability to make use of different cores, which is after-all generally an advantage.
