Japan's Pride, the K Computer, Regains Top Spot in Graph500 Ranking

Supercomputers Open the Doors to the Future

Humans have solved numerous problems using science and technology to create an abundant society and better future. Our efforts continue today in the fields of the environment, space development, and medical care. Supercomputers are what empower us to challenge the limits in these fields and carve out a way to the future.

Supercomputers are designed to perform scientific and technical calculations. Featuring an unbelievably high processing capacity, they perform difficult calculations involving large numbers in a short period of time that regular computers are unable to perform.

Supercomputers are good at computer simulation. They perform calculations and simulate what humans had been unable to know due to the sheer scale, the accompanying danger, or feasibility issues. Examples of such simulation include analyzing global climate change, analyzing the high-temperature of the earth's interior structure, and examining the creation of the universe. The simulation feature of supercomputers allows extremely complicated events to be examined in detail.

Further development of supercomputers is expected to take Japanese industrial technologies to the next level.

17-Day Manual Calculation in Just One Second

Fujitsu and RIKEN completed the joint development of the supercomputer "K" in June, 2012 as a part of the High-Performance Computing Infrastructure (HPCI) initiative led by Japan's Ministry of Education, Culture, Sports, Science and Technology.

The K computer can operate 10 quadrillion calculations (10 to the 16th power or 10 petaflops) in a second. The amount of this calculation is equivalent to that achieved by the Earth's entire population (7 billion people) performing one calculation per second on their calculators for approximately 17 straight days without any break. The K computer can complete the same volume of calculation in just one second.

The K Computer Regains World's Top Spot in Big Data Processing

On July 14, 2015, the K computer regained the world's top spot in the Graph500 ranking. It is an international supercomputer performance ranking concerning big data processing (large-scale graphical analysis).

This achievement is attributed to the efforts of the international joint research group in which RIKEN, Tokyo Institute of Technology, University College Dublin, Kyushu University, and Fujitsu participated. The K computer was last No. 1 in Graph500 in June 2014. The large-scale graphical analysis capacity is important in big data analysis requiring large-scale and complicated data processing. Through this achievement the K computer has proven to the world that it has a high capacity for analyzing big data.

By 2020, the Internet of Things (IoT) is predicted to give rise to a new market across the world generating approximately 200 trillion yen per year; however, the current reality is that a large volume of data is generated but is seldom used. Supercomputers can perform high-speed and extensive analysis of big data.

Big data, when analyzed, has huge potential in all fields. For example, it may contribute to effective medical care. Genome analysis may save the lives of patients or accurately predict reactions to medication. In business, companies with completely different cultural, habitual, or occupational backgrounds may enter into partnerships and create new modes of business as a result of analyzing big data. Solving urban traffic problems throughout the world and connecting distributors, communities, and consumers via a single value chain are other examples of possible contributions big data analysis can make.

Finding answers to a majority of the problems we currently face requires gathering together intelligence and wisdom from around the world and accelerating cutting-edge research. Today, supercomputers are opening doors to innovation. Through developing supercomputers, Fujitsu is continuing its commitment to creating a brighter future for us and our planet.
