I think ms was talking about NUMA architectures. Everything ms says, and everything the article says, is applicable to to all multiprocessor systems, NUMA and non-NUMA alike. They all have shared memory and they all have difficulty because of that. NUMA shares memory in a way that strikes a different balance between the difficulties and the advantages of shared memory than other multiprocessor systems, but it remains a defining characteristic, not just an incidental feature, of multiprocessor systems that they have shared memory.
