detect offline CPUs on Windows

Open bgoglin opened this issue 7 years ago • 0 comments

msconfig on Windows lets you disable some cores (go to "Boot" tab, "Advanced options", "Number of processors"). See that's what "Active" means in dwActiveProcessorMask vs dwNumberOfProcessors in struct _SYSTEM_INFO, and in GetActiveProcessorCount().
