问题描述
限时送ChatGPT账号..是否有 Windows API 或任何方法可以确定我当前的线程在哪个物理处理器/核心上运行?我不需要那个信息.我只是好奇.
Is there a Windows API or any way to determine on which physical processor/core my current thread runs? I don't need that information. I'm just curious.
我对允许线程运行的处理器不感兴趣.我想确切地知道它目前运行的是哪一个.我知道线程从一个切换到另一个非常快...
I'm not interested in the processors the thread is allowed to run on. I would like to know on exactly which one it currently runs. I know that the threads switch pretty fast from one to another...
推荐答案
线程经常会从处理器切换到处理器,所以有点无意义,但你可以使用 GetCurrentProcessorNumber
.
Threads will often switch from processor to processor, so it's kind of meaningless, but you can use GetCurrentProcessorNumber
.
正如其他人所说,您可以使用 GetProcessAffinityMask
或 GetThreadIdealProcessor
,但这些只有在您已经为线程设置了关联掩码或理想处理器时才有效.
As others have said, you can use GetProcessAffinityMask
or GetThreadIdealProcessor
, but those will only work if you've already set an affinity mask or ideal processor for the thread.
