  • Supercomputing-Japan: a competitive assessment

    Publication Year: 1992, Page(s):42 - 47
    Cited by:  Papers (3)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1145 KB)

    Japanese supercomputers (e.g. Hitac S-3800, NEC SX-3R, Fujitsu VP2000) are described and compared with US machines. The Japanese approach has been to develop high-speed single processor systems with vector processing functions which are driven by the fastest technologies. Ease of programming and of use are taken into account. The result has been first-rate applications for supercomputers, but soft... View full abstract»

    The need for high-speed data communications and mass storage systems for supercomputing is examined. The former could be serious bottlenecks in the not-too-distant future, because their capabilities have not kept up with those of supercomputers themselves. The potential of fiber-optic technologies for meeting data communication requirements is discussed, and research around the world is briefly ci... View full abstract»

    The role of visualization and its capabilities are discussed. The loss of information incurred in translating a three-dimensional scene into a two-dimensional image plane and ways of compensating for it are considered. The need for interactive capability is stressed. The dichotomy between the use of visualization for analysis and for communication is traced to the way the technology evolved. That ...

    The packaging requirements imposed by 1-GHz clock rates and ways to meet them are considered. For supercomputers, many more input/output connections must be squeezed into less space and greater quantities of heat must be removed, also in less space. To cope with these problems, engineers are adding more interconnection layers, multichip modules, adopting exotic materials, such as diamond, and are ... View full abstract»

    Advanced technologies and their potential for the next generation of supercomputers are addressed. Among them are bacteria serving as lithographic masks, computer chips grown from organic molecules, beams of light in free space acting as input/output 'buses', and architectures without logic gates that yield an answer without calculations. The need for a universal computational model for parallel p... View full abstract»
