How do I set CPU affinity in Linux?

command. For example, taskset -c 0,1 my_program
will run my_program
on CPU cores 0 and 1.
What if I want to set it for a running process?
You can use taskset
with the process ID. For example, taskset -p 0x3 <PID>
sets the affinity for the process with that PID to cores 0 and 1.
Are there any GUI tools for this?

or system monitor
can help manage CPU affinity through a graphical interface.
Can I set CPU affinity permanently?
To set CPU affinity permanently, you can modify the service configuration files or use systemd
