No. 548: Successful development of a technology for high-speed decentralized processing of a large amount of data (June 28, 2012)

National Institute of Information and Communications Technology (NICT) developed a technology to process a large amount of data by connecting multiple computers with the dedicated line. The new technology allows the user to conduct continuous high-speed processing of a large amount of data by segmenting them into small sizes as if he is using one computer. It will be utilized for the analysis of big data obtained from the observation of space and geoenvironmental research that even a supercomputer cannot process well.

The new system is called “Science Cloud.” It connects computers in NICT, Osaka University, and Nagoya University, and the user can use the system via the Internet without a sense of discomfort. The system can memorize up to 2 petabytes that is equivalent to 500,000 DVDs, and has about 400 computation processing circuits. It specializes in decentralized high-speed processing. A research team let the system read observational data collected by satellites. The data were as big as 15 terabytes that is equivalent to 3,500 DVDs. With these data, the system successfully created a stereoscopic vision that reproduces about the two-hour move of solar wind in one day. Because there are numerous pieces of equipment to observe such meteorological data as rainfall and atmospheric change, the research team expects that the new system will analyze climate with data collected from them.
