Does a thread run on the same CPU/core throughout its life?
multithreading, windows
Solution
does a thread change the CPU/core during its lifetime?
It can. It doesn't necessarily change, but there is nothing preventing the operating system from moving a thread between cores.
The Windows API does provide some control over this via SetThreadIdealProcessor or SetThreadAffinityMask and SetProcessAffinityMask, if you need to control a thread's operation.
Problem
In Windows on a multiprocessor machine, does a thread change the CPU/core during its lifetime?
