Most of the stuff on the web suggests that linux doesn't (or didn't) scale particularly well past 4 processors on Intel and I doubt there are many people in the world running this since Solaris on UltraSPARC is more common in this niche. Although I think a lot of current linux development work is on SMP and multi processor scalability so if you were brave enough to run a bleeding edge kernel with dodgy patches you might get better results. And as ever in the linux world what I saying may be totally out of date as of last week. 2.6 is likely to have NUMA.

I suspect MPP (message passing) versus SMP (shared memory) is a CS religious issue and don't claim to understand all the issues but isn't MPP generally very slow? I suppose you have to draw tradeoff graphs. AFAIK the big Suns *do* use SMP and I can't think of any mainstream UNIX server kernel which uses MPP (maybe Alphas running OSF?). Although Apple's Darwin is based on Mach (and other things) there seems to be a bit of doubt about how well supported the Mach stuff is and they seem to use SMP for their multiprocessor support. What's better in theory often doesn't happen in practice since if the CS academics of a decade back had predicted future technology correctly then we would be all running microkernels on RISC chips today.

Personally, although SMP is one of the major thrusts of 2.5 (thru finer grained locks, better cache coherency, better memory management etc), I think MPP is a better way to go. Seeing as these mini-itx boards are now so cheap and low powered (as in VAs, see: http://www.mini-itx.com/), I was toying with the idea of making myself a small cluster of these and running them off a humungous (60A) 12V PSU I have lying around not doing (many) Radio Ham duties these days.
