Thanks to a rebuild, the world’s top supercomputer is more than four times as powerful than its nearest rival.<\/p>\n

The K Computer from Japan, which operates at more than 10 petaflops per second, has again topped the bi-annual Top500 list<\/a> of the world’s top supercomputers.<\/p>\n

The K Computer is made up of 705,024 SPARC64 processors and recorded a peak performance of 10.51 petaflop\/s, or 10 quadrillion calculations per second in tests. The K Computer previously recorded a top speed of 8.16 petaflop\/s to take the top spot in the June 2011 release of the Top 500 list.<\/p>\n

In second place in the November Top500 list is still the Chinese made Tianhe-1A system which returned a relatively measly top speed of 2.57 petaflop\/s. A year ago that performance was enough to guarantee the Chinese supercomputer the top spot on the Top500.<\/p>\n

39 systems in this release use GPUs (graphical processing units) compared with 17 systems six months ago. 35 of these use Nvidia chips.<\/p>\n

More than half (62%) of the systems in the Top500 now use processors with six or more cores.<\/p>\n

The dominant processor maker is still Intel with 76.8% of the Top500 systems. AMD is in second place with 12.6% and IBM Power processors account for 9.85% of the Top500.<\/p>\n

The entry level to be included in the Top500 list continues to climb and now sits at 50.9 teraflop\/s. Six months ago 39.1 teraflop\/s was adequate to secure a place in the Top500.<\/p>\n

On the hardware front IBM retained its lead, accounting for 223 of the Top500 systems. HP held onto second place with 141 systems.<\/p>\n

Linux continues to dominate supercomputing and is used exclusively in 457 (91.4%) of the Top500 systems.<\/p>\n

Unix variants account for 23 of the remaining systems and there are 15 mixed OS environments in the list.<\/p>\n

Four Windows-based systems made the Top500 and 1 BSD-based system rounded out the Top500.<\/p>\n","protected":false},"excerpt":{"rendered":"
