The code getting the number of processors on Windows is different between the multiprocessing (Python 3.3) and os (Python 3.5) modules.
multiprocessing (old code):
try:
num = int(os.environ['NUMBER_OF_PROCESSORS'])
except (ValueError, KeyError):
num = 0
os (new code):
SYSTEM_INFO sysinfo;
GetSystemInfo(&sysinfo);
ncpu = sysinfo.dwNumberOfProcessors;
os.cpu_count() is already implemented with GetSystemInfo() in Python 3.5, so this issue can be closed. Thanks for the reminder Mark, it was useful to double check.
If you want to take a look at the source code:
