Current tightly coupled MPP's offer more or less uniform access to off processor memory with serious degradation
Future systems will return to situation of 80's where both data locality and nearest neighbor access will be essential for good performance
Tremendous reward for Latency Tolerant algorithms and software support for this
Note we need exactly the same characteristics in MetaComputing today
World Wide Web is a good practice for Tomorrow's PetaFlop Machine!
