Hi Adriano, On the SGI Altix system we've been getting good results with the O(1) scheduler. > The limits of the bricks for SMP are 4 proc, how could I assume linear > scalability for 8 proc having memory latency accesing the others bricks > through R-Brick maybe? 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. --steve
