Abstract :
The K computer is a distributed memory super-computer system with 82,944 compute nodes and 5,184 I/O nodes that was jointly developed by RIKEN and Fujitsu as a Japanese national project. Its development began in 2006 and was completed in June, 2012. By achieving the LINPACK performance of 10.51 peta-FLOPS, the K computer ranked first for two consecutive TOP500 list in June and November 2011. During its adjustment, part of the K computer was served, gradually increasing computing resources, to experts in computational science as a trial and was used for performance optimization of users´ application codes.
