What operating system are you using? I am using Red Hat Enterprise 5.2, kernel 2.6.18-92.el5 x86_64 > I know that there are ways to bind processes to a CPU on Linux, I'm not > sure how to assign multiple processes to multiple CPUs.

With this the other processes and S.O by default will use the node 0? thanks... ¿Tienes cámara digital, más de una cuenta de email, planeas fiestas o blogueas? Entonces, necesitas Windows Live |
