What is CPU affinity in Linux and how can I set it?
CPU affinity is the assignment of a process to a specific CPU core. This can improve performance by reducing cache misses.
How do I check the current CPU affinity of a running process?
You can check the CPU affinity of a running process using the taskset
command followed by the process ID.
Can you give me an example of using taskset?
Sure! To set a process with PID 1234 to run only on CPU core 0, you would use: taskset -p 0x1 1234
.
Are there any tools to manage CPU affinity more easily?
Yes, tools like htop
allow you to set CPU affinity interactively for processes.
