K SUPERCOMPUTER, RIKEN Advanced Institute for Computational Science (AICS), Japan
The “K” supercomputer, a joint project by Fujitsu and the RIKEN center, has overtaken China’s Tianhe-1A system to gain the top spot on the updated list. The K computer system, currently in the configuration stage, features 68,544 Sparc 64 CPUs, each with eight cores, for a total of 548,352 cores—almost twice as many as any other system in the TOP500. The K Computer is also more powerful than the next five systems on the list combined. The system is deployed across 672 computer racks and has a power consumption of 9.89 megawatts. The K Computer’s name draws upon the Japanese word “Kei” for 10^16 (ten quadrillions), representing the system’s performance goal of 10 petaflops.
TIANHE-1A, National Supercomputing Center, Tianjin, China
The Chinese Tianhe-1A system at the National Supercomputer Center in Tianjin slipped back into second in the latest survey, achieving a performance level of 2.6 petaflop/s (quadrillions of calculations per second). Tianhe-1A is one of the 19 systems in the Top 500 that use NVIDIA GPUs (graphics processing units) to accelerate computation, up from 17 in the November survey. Tianhe-1A was nominated the fastest supercomputer in 2010 but this year Japan really outdone themselves with the K-Systems.
JAGUAR, Oak Ridge National Laboratory
Jaguar was the top performer in the June 2010 survey, but fell back to second in November 2010 and now slips to third overall with a 1.75 petaflop performance speed running the Linpack benchmark. Jaguar is a Cray XT5 system located at the Department of Energy’s Oak Ridge Leadership Computing Facility in Tennessee. While Jaguar fell a few flops short this year, it retains a leadership position in supercomputing style with its striking Jaguar motif.

NEBULAE, China
Nebulae, which is located at the National Supercomputing Centre in Shenzhen, China, achieved 1.271 PFlop/s to rank fourth overall, down one position from the November survey. Nebulae was built from a Dawning TC3600 Blade system with Intel X5650 processors and NVIDIA Tesla C2050 GPU.
Like the top-ranked Tianhe system, Tsubame 2.0 is a successor system that builds upon the design of a previously-ranked system. Tsubame 2.0 was developed by the Tokyo Institute of Technology in collaboration with NEC and HP, and is powered by more than 1,400 nodes using both HP Proliant servers and NVIDIA Tesla GPUs. It is Japan’s highest-ranked supercomputer. Plans are being developed for Tsubame 3.0.
Most of the world supercomputers are not being used efficiently since they are mostly used for showing off either in processing speed or in the style of the supercomputers. Even though some are being used for really huge calculations but most of the times countries want to show how far advanced they are. Next time I will post on the next five on the list.
