Xeon Kernel clarification

moved from Server forum>

I am currently testing the 64-bit FC4 on a single Xeon system.

With Ubuntu I had to update the 64-bit AMD kernel that was installed by default by doing>

apt-get install linux-amd64-xeon

to get the Xeon specific kernel.

Do I have to do something similar with yum after the 64-bit FC4 kernel is installed?

You can always get the full kernel source from www.kernel.org.
And fedora comes with a prety good compiler chain. You can make a custom kernel for your particular setup. I know i do, and my kernels always perform faster than the stock kernels.
Just don't delete the stock kernel, in case something goes wrong.

I'm a bit too much of a beginner to try that one as yet. But a good suggestion for the future.

Any recommendations for a good HOWTO?

No. There is just one x86_64 FC4 kernel.

Thanks for clarifying that.

One last question! > what are the advantages / disadvantages of using the standard x86_64 FC4 kernel versus the SMP version, because I notice that both were automatically installed?

The SMP kernel will make use of the HT (HyperThreading) feature of your processor, so make that the default kernel. The non-SMP one can be thought of as being there for troubleshooting.

SMP = Multi processor. The AMD / Intel dual cores, HT tech, and the true multi-processor systems will use this kernel to make use of both cores, the HT tech, or both cpus respectively
