The 512CPU SGI thing I was talking about is a Shared Memory NUMA system running single system image, which is different from MPP or a clustered system. It runs upto 512 CPUs in a single node.
If a kernel scales well with single image on such a system, it can very well scale (upto the point where it comes to hardware limitations) on 512 CPU SMP box if it was available. And NASA runs such a box in production, with Linux, for "Mission Critical" stuff.
