Hi I am wondering if their is a code to start a terminal emulator dedicated to run off a pasific core.

i have a script wrote up that starts my servers. i run three game servers on a dual core system. their designed to run off one core.
in a terminal emulator. so is their a code i can add in my script that will tell it to use a pasific core? or another way?

i am useing opensuse 11.2 and gui kde

thanks for your help.

use "taskset"

Quote:

taskset (core number) -p (process number)

so:

Quote:

taskset 1 -p 4129

hi thanks for your reply what if its not a process yet. like can i tell it to open a terminal and tun that terminal under core 1 and another terminal to run off core 2? i understand the code thanks. just wondering how i get the process number if its not running yet? or is it somethin im going to have to set after the servers are up and running?

thanks.
