1. At first, run this command by superuser. This will assign CPU cores other than #3 for all processes. But it will cause some errors, I'm not sure it is really perfect.

    ps -e -o pid= | sudo xargs -n 1 taskset -p -a 0xFFFFFFF7 2> /dev/null > /dev/null

2. And then, run those codes in your program. This will assign CPU core #3 exclusively for the thread.
