DualCore maybe? you can see the number of your physical processors with something like this: [root@box ~]# cat /proc/cpuinfo |grep "physical id"|sort -u physical id : 0 physical id : 1 Pozdrav Zoran Dusan Djordjevic <dj.dule.liste@xxxxxxxxx> Enviado por: redhat-list-bounces@xxxxxxxxxx 17/12/2009 10:48 Por favor, responda a General Red Hat Linux discussion list <redhat-list@xxxxxxxxxx> Para redhat-list@xxxxxxxxxx cc Asunto How many processors are active in box ? Hi all, I should perform upgrades to a box that I did not install so I am out of documents. What confuses me is following: -According to /etc/issue, it is running RHEL 5.2 (Red Hat Enterprise Linux Server release 5.2 (Tikanga)). As far as I know. ES supports up to 2 processors -It seems server do have 4 x Opteron 850 physical processors -cat /proc/cpuinfo shows that box do have 4 processors I am confused here. If only 2 processors are supported by ES, how comes I can see all of them ? Are they active all, or just I can see them but kernel uses only 2 ? Why someone installed ES on 4 processors box is another question, not for here :) Thank you in advance.
