SGI systems include x86 versions with this CPU count - for example, NASA recently bought an Altix ICE blade server with 4096 Xeon CPUs: http://www.sgi.com/company_info/newsroom/press_releases/2... However, the line between this blade-based system and traditional Altix systems is not entirely clear, though presumably with the right problem a blade server would be just as good.

Big shared-memory x86 machines Posted Apr 20, 2008 8:48 UTC (Sun) by joib (guest, #8541) [Link] That's correct, Altix ICE (and Altix XE) are clusters. Each 2-socket node runs its own kernel, and there is no shared memory between nodes, so inter-node communication is with message passing (MPI). AFAIK all big shared-memory machines SGI makes are Itanium-based. I suspect the answer to this conundrum is that this changeset just increases some previous x86-only max-cpu limit, and the mention of 4096-way machines refers to the Itanium-based SGI Altix.
Big shared-memory x86 machines Posted Apr 22, 2008 12:46 UTC (Tue) by knan (subscriber, #3940) [Link] There are development going on inside SGI for future and one-off machines, you know. The patch came from a SGI employee, and definitely is for x86-64. While their current big boxes are IA64, future machines doesn't need to be...
