Hi Christoph,
Following is SGI's stand on this issue:

SGI recommends that customers use the -sn2 kernel. This is the kernel 
that is installed by our factory when we ship systems. The -sn2 
kernel is also the kernel that must be run if the Altix has more that 
128 CPUs. So I'd be surprised it the majority of the Altix systems in 
the field are not running the -sn2 kernel.

The my argument is wrong for SuSE ;-)  This still needs to be a runtime
switch though, not just for this reason.  Platform ifdefs are not the
way to go.

Hi Ravinandan,

Ditto for SGI Altix on Red Hat -- platform specific ifdefs are not the proper 
way to do this.

P.
