Differences between default, smp, and bigsmp kernels ?


I think this must be a very basic question. What are the differences between the following kernels?

- kernels 2.6.5-7.139-default
- kernels 2.6.5-7.139-smp
- kernels 2.6.5-7.139-bigsmp

(FYI, I'm trying to install SuSE9 Linux Enterprise SP1)

Thx for helping a newbie in advance.

SMP is Symmetric Multi-Processor. An SMP kernel is one compiled to support multiple CPU's in the same machine. If you have a single processor machine then you probably want the default kernel.

Thx for your quick response.

Anyone else has an explanation for "bigsmp"

I'd be assuming something with a lot of CPUs Probably SMP is for dual CPU and bigsmp is for anything more

With a P4 3.2, do you use smp or default ? I'd think smp, but not sure.

Read my first response: SMP is Symmetric MULTI Processor. For computers using MORE THAN ONE CPU. Do you have more than one CPU? If not then use default.

Fascinating that you think I'm not capable of reading, let alone comprehension.

For your information, any P4 over 2.8GHz comes with HT-Technology, thus my P4 3.2 uses HT as well, which lead to my initial question, which you are yet to answer to your knowledge oh great one.

Hey, if you're so clever solve your own problem.

But seeing as I'm so lovely (), it is possible that you could benefit from an SMP kernel. CPU performance should increase, but it's possible IO performance will decrease. Multitasking should be improved, though it's debatable whether that's really to do with SMP or just the HT technology.

The choice (as they say) is yours.

There is an option in the kernel config to enable HT support or not, I couldn't tell you whether those SMP kernels have that support or not, maybe you might be better to bite the bullet and compile your own kernel. It's not really all that difficult
