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 :-) -- Jerry Feldman <gaf@blu.org> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9
