You're looking for physical id and core id. They both start from zero. I'm looking at a dual quad core system right now. I have 8 entries that look like: physical id: 0 core id: 0 physical id: 0 core id: 1 ... physical id: 1 core id: 3 You can also get CPU info with Code:
dmesg | grep -i cpu A quick way to see how many cores total is to run 'top' and then press '1' on your keyboard. That will expand out the processor information at the top and will show you all the cores so you can do a quick count. |
