For the seventh consecutive time, Japan’s K computer has taken the top ranking on the Graph500 ranking, which gauges the ability of supercomputers on data-intensive loads rather than simple speed. The goal of the benchmark is to improve computing involving complex data problems in “big data” areas such as cybersecurity, medical informatics, data enrichment, social networks, symbolic networks, and modeling neuronal circuits in the brain. The top rank this time was won by a collaboration involving RIKEN, Kyushu University, Tokyo Institute of Technology, the Barcelona Supercomputing Center, Fujitsu, and Fixstars Corporation. The achievement was announced on June 27 at the ISC High Performance conference in Frankfurt. In order to encourage the further development of such tools, the group has published the program as open source code on the GitHub repository.
