That is the largest machine around, I suppose the guys from SGI have some with even more.
SGI, HP, IBM, and Red Hat all are testing with many CPUs. I think the
more important issue is scaling. I couldn't quickly find any recent
articles, but tests have shown Linux to scale well at 64 CPUs. I
suspect that you could probably find a paper on the SGI, HP, or IBM
sites that shows scaling data for more than 64. Currently, I can't
afford a 64-CPU system :-)
