Japan's National Institute of Advanced Industrial Science and Technology (AIST) plans to build a super-efficient supercomputer that could achieve the top ranking in the Top500 supercomputer list by the end of next year.
The AI Bridging Cloud Infrastructure is intended for use by startups, existing industrial supercomputing users, and academia. The planned supercomputer would have a processing capacity of 130 petaflops and outperform the current world leader, China's Sunway TaihuLight, which delivers 93 petaflops.
AIST also wants to make its new supercomputer one of the most efficient in the world, aiming for a power consumption of less than 3 megawatts. Japan's most powerful supercomputer, Oakforest-PACS, currently delivers 13.6 petaflops for the same amount of power. AIST wants its new system to have a power usage effectiveness of less than 1.1, a value attained only by the world's most efficient data centers.
The AIST researchers plan to use liquid cooling to help meet their goals for the new system.
Other countries have optimized their top supercomputers for calculations such as atmospheric modeling or nuclear weapon simulations, but AIST is focusing on machine-learning and deep-learning applications in artificial intelligence.
