Mythology says that vendors like Tera cannot afford development and no market for high-end machines. High-bandwidth machines, SMPs, vector or multithreaded, and network topology for high bandwidth will improve. NT will never scale to high-end SMPs. Even industrial applications have abunded parallelism, as he stated. Tadashi Watanabe, NEC, first presented the history of architectures, operating systems and languages.
Past experiences show the memory bandwidth bottleneck, scalability problems of SMPs.
The microprocessor performance is dependent on cache and low efficiency of micro based MPPs. The auto vectorisations have matured, auto parallelization must be enhanced on procedure level. Then the speaker discussed the ongoing processor design trends. Different chip architectures are possible, his optimal choice would be a micro processor and one or several vectors.
