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
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...
