Technology:
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.
