kernel vs kernel smp
 

I have FC2 installed. Grub gives me the option of starting up with either "kernel" or "kernel smp". I believe it defaults to the smp version. Can someone tell me the difference?

thanks!

hi

smp stands for symetrical multi processor. it's used for computer with more than one procesor. although your probably not using one of these expensive pieces of kit, i'd suggest your using a processor that suports hyperthreading. eg intel pentium 4. i have 2 machines, ones a P 4 2.4 and the others a celeron 2.6, both show the smp kernel choice upon boot. i hope this makes a little sense

thanks, that makes a lot of sense. I am using a dual 500Mhz pc.

i thought that one of the positive features of the new {2.6} kernel was NUMA rather than SMP. i would look into why it comes up with an SMP option. perhaps someone a bit more knowledgeable than i shall come along and answer this question...

all the best,

i found a site discussing the NUMA features--appearantly NUMA is a hardware option that the 2.6 kernel is capable of supporting, which would be why yours comes up SMP (there is little NUMA hardware out there from what i can tell...)

sorry for any confusion, i had thought that NUMA was completely software...

cheers,
