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.

But the workloads used on this sort of machine are all
user-land HPC which spend almost no time in the kernel,
making kernel scalability claims somewhat dubious.
I would be much more impressed with database, SPECjappserver
or other workloads with a significant kernel component.
