The Tsubame 3.0 will use CPUs and image-processing semiconductor chips that are already on the market. Development costs are expected to reach 3.2-4 billion yen.
The University of Tokyo also will team up with the University of Tsukuba to develop a next-generation supercomputer, which will be on par with the Tsubame in terms of performance.
The K supervcomputer, jointly developed by Fujitsu and Riken, a government-backed research institute, took the crown in the global ranking of computational performance in 2011. It was overtaken by China's Tianhe-2 the following year and is now in fourth place.
