I am working on some performance modelling for shared-memory multiprocessor machines and I was wondering if anyone out there could tell me the memory bandwidth on the SGI 4D/3x0 series machines. I am most interested in the main memory to secondary cache link, but the secondary cache to primary cache link is of interest also. I believe that the cpu's all share the same secondary cache, so that I would assume that the main memory is single-ported. Is the secondary cache multi-ported, or do the cpu's access it via a shared bus? Thanks for any answers! -- John D.
