HAMBURG, Germany–A Japanese supercomputer capable of performing more than 8 quadrillion calculations per second (petaflop/s) is the new number one system in the world.
The system, called the K Computer, is at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe.
The 37th edition of the closely watched TOP500 list was released Monday, June 20, at the 2011 International Supercomputing Conference in Hamburg. The ranking of all systems is based on how fast they run Linpack, a benchmark application developed to solve a dense system of linear equations.
For the first time, all of the top 10 systems achieved petaflop/s performance. The U.S. is tops in petaflop/s with five systems performing at that level; Japan and China have two each, and France has one.
Bumped to second place after capturing No. 1 on the previous list is the Tianhe-1A supercomputer the National Supercomputing Center in Tianjin, China, with a performance at 2.6 petaflop/s. Also moving down a notch was Jaguar, a Cray supercomputer at the U.S. Department of Energy’s (DOE’s) Oak Ridge National Laboratory, at No. 3 with 1.75 petaflop/s.
