In collaboration with RIKEN, Tokyo Institute of Technology, Kyushu University, Fujitsu, and University College Dublin (Ireland), the supercomputer "K computer" announced in November the international ranking of supercomputers for big data processing Graph11. Won the 500st place in. This is the result following July 1.

　In recent years, a huge amount of data (big data) on the Internet has been actively used when investigating human social activities in detail.Big data is represented as a large graph in such analysis, but computer analysis is indispensable.For example, graph analysis is used in many fields, from analysis of connections between users of social services, security of financial transactions, to medical care and science.Big data analysis is considered to be indispensable for clarifying the information necessary to solve various problems and issues occurring in the real world.Therefore, since the use of graph analysis will expand in the future, Graph500, which competes for the speed of computer graph analysis, started in 2010.

In general simulations used in scientific research, there are many regular calculations that computers are good at, whereas in graph analysis, most of them are irregular calculations.The result shows the high performance of the computer that can handle this.At the same time, it also shows the high level of software technology for maximizing the performance of computers.

In the future, we plan to further improve the performance by improving the program.By doing so, we will contribute to solving the problems that society faces.
