[英]Finding out which module set processor affinity mask
I am running into an issue where my 32-bit command-line application, when started from Windows Command Prompt or other means, is set to only use the first 32 CPU cores on a 64-core system. 我遇到一个问题,即从Windows命令提示符或其他方式启动时,我的32位命令行应用程序设置为仅使用64核系统上的前32个CPU核。 Looking at that process's CPU affinity mask in Task Manager, I can see that only the first 32 CPUs are checked, and the last 32 CPUs are unchecked. 在任务管理器中查看该进程的CPU关联掩码,我可以看到仅前32个CPU被选中,而后32个CPU被取消选中。
I made sure my code doesn't call SetProcessAffinityMask, but how can I see if any of the third party modules call this function? 我确保我的代码未调用SetProcessAffinityMask,但是如何查看是否有任何第三方模块调用此函数? And would doing things like calling SetThreadPriority change the CPU affinity mask? 并通过调用SetThreadPriority之类的方法来更改CPU关联掩码吗?
