That's not impressing me. Not at all.

SMP as a whole is not a fully developed "thing" There are 
numerous design issues, lots of them highly complicated, 
some pure theoretically, others CPU or CPU-implementation bound.

For OpenBSD, as a project with as main goal serious security 
I think SMP might never really take off as long as Moore's 
"law" is operational. Better wait 1.5 years and you get a 
machine equally secure, twice as fast and all for the same 
money.

??? I thougth people here tried to explain to you that this 
"talking in order to push programmers" is just a plain waste 
of time.

Well, start writing SMP code, I would be happy with it!


Please start figuring what you need and why, you will 
probably see you won't really need SMP. If you know what you 
need and you are sure Moore won't fix it for free in at 
least 3 years, start designing a solution. If the design is 
ready, start writing code. If your design is truly 
interesting and realistic people will gather and write code 
for it.
