“For contributions to the architectural design of supercomputers with multiple/parallel vector pipelines and programmable vector caches’s fastest supercomputer from 2002 to 2004”


Tadashi Watanabe is a Japanese computer engineer. Watanabe is the project manager of the RIKEN Next-Generation Supercomputer R&D Center. He played a central role in the development of the NEC SX architecture.

The Next-Generation Supercomputer will be a driving force behind Japanese science and technology and an essential foundation for advanced research and development. It will be used in the natural sciences (physics, chemistry, and biology), nanoscience, the life sciences, engineering, and the prediction of environmental change and natural disasters. To build the supercomputer, we have to develop many pieces of cutting-edge computer technology, from semiconductors to system software, and to continue developing supercomputers in the future, we will have to keep up this level of R&D in Japan. We also plan to make these technologies available to other research institutes, where we hope they will contribute to Japanese information technology in general. For all these purposes, we are gathering Japanese expertise and putting our full efforts into building the fastest supercomputer in the world.
