Hi Adriano,

On the SGI Altix system we've been getting good results with the
O(1) scheduler.

There are many factors that can affect getting good "scalability" beyond
8p (e.g., hardware design, kernel scalability, user v. kernel workload, 
user app scalability, I/O subsystem, etc) -- having a good hardware design 
with a fast system interconnect is essential.
