In RIKEN, an applied research institute in Japan, and Fujitsu recently announced that the "K computer," a supercomputer currently under their joint development, has achieved a LINPACK benchmark performance of 10.51 petaflops (10.51 quadrillion floating point operations per second).
The supercomputer system used for these tests is in its final configuration of 864 racks, comprising a total of 88,128 interconnected CPUs. With an execution efficiency of 93.2%, this system further exceeds its first place winning performance on the 37th TOP500 list international ranking of supercomputers published in June 2011, where it scored 93.0%.
Although development is still underway to adjust the system software, the K computer achieved the goal of a LINPACK score of 10 petaflops, a performance target set as a national core technology as part of Japan's 3rd Science and Technology Basic Plan.
RIKEN and Fujitsu have been working together to develop the K computer, with the aim of beginning shared use by November 2012, as a part of the High-Performance Computing Infrastructure (HPCI) initiative led by Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT). The K computer brings together leading-edge technologies, including ultrafast and energy-efficient CPUs and a network capable of an immense amount of interconnectivity, to create a high-performance, highly-reliable supercomputer.
