About smp-kernel

[satimis]

HI folks,


Is smp-kernel enabled on CentOS4?

Which command shall I use to check it;

dmesg | grep "^ cpu"

OR

top -S


TIA

Use cat /proc/cpuinfo
You should see two processors in the output if you have an SMP kernel (and of course two CPUs ;) ).

Also, you should see SMP mentioned somewhere in the output of uname -a

Hi falko,

I'm running AMD Athlon64 X2 (dual core) AM2 cpu

# cat /proc/cupinfo
cat: /proc/cupinfo: No such file or directory


# uname -a
Linux host 2.6.16.29 #1 Sat Sep 30 14:08:18 BST 2006 x86_64 x86_64 x86_64 GNU/Linux

This is not an SMP kernel.
A SMP kernel has "SMP" within the kernel name.

I know how to replace it in a safe way on Debian like systems but not for Fedora. So i can't give you more advise about that point.

Have you build your own custom kernel and are you running that? The output does not look familiar for a standard distro....

Hi martinfst,

I haven't installed CentOS-4.4. I have its CD as well as arch64 Linux CD available. I expect to clarify nVidia driver issue as well as smp-kernel before deciding to go with which of them.

I ran that command on slamd64-11.0. I'm now installing fred's recompiled smp-kernel and encountering some problem. Sorry for making that confusion.

You don't have an SMP kernel installed.

Dose SMP kernel works on single core CPU? Tks


Edit:
Would it be an advantage if building all items on the kernel as module instead of "enabled"?

You'd then need a ramdisk if your file system drivers are modules.
