No of cores that R is operating on

Hi all,

When I go to task manager and check. The number of cores is 2. But when I run below code, It is showing as 4. Why this mismatch?

I don't know for sure but would guess its to do with difference between physical and logical cores?.

It is probably returning the number of threads you have on that CPU.
