The “K” supercomputer, a joint project by Fujitsu and the RIKEN center, is now the No. 2 system. Installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan, the K Computer it achieved an impressive 10.51 Petaflop/s on the Linpack benchmark using 705,024 SPARC64 processing cores. The K Computer is the first supercomputer to achieve a performance level of 10 Petaflop/s, or 10 quadrillion calculations per second. The K computer had taken the No. 1 position in both June 2011 and November 2011.
