Installing on SMP box.

Hi all!

I am to try a SMP install of Gentoo, and was wondering if there are any
specail flags i need to set to make it more specialized for that.
What is a good minimal but still flexible set of flags?
I dont want to set them all just to be able to install some more "specialized"
software later on. I like the minimmal/fast thought :)

Rickard,

Do you mean in terms of kernel configuration options,
or CFLAGS/USEFLAGS in make.conf?

CFLAGS/USEFLAGS.

The kernel comes later :)

There really shouldn't be anything special in terms of
CFLAGS. Any multithreaded apps should add required
flags in their makes files.

For USE flags... I'm not sure... I've never installed
Gentoo on an SMP box. (anyone? Bueller? anyone?)

Just make sure to set MAKEOPTS="-jX" correctly and maybe USE="smp" if
you use gimp.

Indeed. I've installed Gentoo on a couple of SMP boxes, and it Just Works,
as long as you remember to build the kernel with SMP support. You don't even
*have* to use MAKEOPTS="-j<number>", but if you don't, you won't exploit
more than one processor while building things.
