A pretty nice discussion of what happens when you set up 4096 CPUs on one system

[ron minnich]

Rusty Russel is a really good guy, and his writing is always fun. On
this page he discusses what they had to do to get 4096-bit cpu masks
into linux. 4096-bit masks are needed when you have a 4096-cpu shared
memory machine from SGI. I saw an SGi talk on this work this morning
and it was kind of interesting.
