[SuSE Linux] Dual Processor Motherboards
Hello It is my understanding that SuSE Linux 5.2 with support and use dual processors correct? What kind of speed increase or advantage can I expect? Do I have to recompile my kernel to support the two processors? ( right now I'm using only one processor) Thanks Chris - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e

Yes, the kernel on our distribution can support SMP boards after you recompile it, just like any other regular linux kernel.

This depends on your application, but normally the linux kernel uses both CPUs to share the load.

Yes. Edit /usr/src/linux/Makefile, there is a line beginning with "SMP=". Set this to "1" and recompile it.

Hello It is my understanding that SuSE Linux 5.2 with support and use dual processors correct?
Yes. As I recall, there's support for more than two as well.
What kind of speed increase or advantage can I expect?
Depends on the applications and processors, but quite a bit of performance increase is reported (don't have any SMP systems here yet).

Yes again, you'll have to edit your Makefile in your kernel source dir, read the docs on smp in your kernel dir, Documentation dir, smp.tex for more info.
