Full Version: kernel for 2 quad core

I have a server with intel quad core processor, but due to demand, we plan to add second quad core processor to that server, my question is, will the current kernel will automatically detect the second quad core processor on the same machine? I have not personally tried it.

btw, I'm using Centos 5 2.6.18-xx.el5 #1 SMP, does this mean that support for what am going to do is out of the box?

thanks! biggrin.gif

Should work right out of the box. If not, you have to either reinstall the kernel, or (simpler) run mkinitcpio to rebuild the ramdisk.

thanks.

Yep, would have to second that, since SMP supposedly supports up to 16 processors, unless I'm mistaken and it was increased even further.

Easiest way to see what your kernel supports.

CODE
# grep NR_CPUS /boot/config-2.6.18-53.1.14.el5
CONFIG_NR_CPUS=32


This is an i686 laptop.

If your running 64-bit version on your server, it should be 64. 64 is set on Fedora 8x64 but I don't have a x64 Centos server at home. Either case if it is only 32 that should cover your 8 smile.gif
