no. the origin architecture (mips) was developed into the ia64-based altix.
there is no current numalink-based system other than ia64. it's conceivable
that this will change, since intel periodically makes noises about ia64
and x86_64 sharing infrastructure. that seems very attractive, but otoh
the market for large SMP is quite small.

it's unrelated. is that different enough? ;)
