aioshin Posted February 21, 2008 Report Share Posted February 21, 2008 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! :D [moved from Hardware by spinynorman] Link to comment Share on other sites More sharing options...
scarecrow Posted February 21, 2008 Report Share Posted February 21, 2008 Should work right out of the box. If not, you have to either reinstall the kernel, or (simpler) run mkinitcpio to rebuild the ramdisk. Link to comment Share on other sites More sharing options...

ianw1974 Posted February 21, 2008 Report Share Posted February 21, 2008 Yep, would have to second that, since SMP supposedly supports up to 16 processors, unless I'm mistaken and it was increased even further. Link to comment Share on other sites More sharing options...
jlc Posted March 30, 2008 Report Share Posted March 30, 2008 I know this is late and I reply to post twice a year :) Easiest way to see what your kernel supports. # 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 :) Link to comment Share on other sites More sharing options...
