Greece's Super-Computer Shunted Off Top 500 List as China's Share Surges Up

ARIS-SupercomputerThe Greek Research and Technology Network (GRNET) supercomputer “ARIS” has been shunted off the Top500 list of the world’s most powerful supercomputers, based on the new list published in November. The ARIS had ranked 468th in June, soon after it was first deployed.
China’s Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, has retained its position as the world’s No. 1 system for the sixth consecutive time, according to the 46th edition of the twice-yearly TOP500 list.
Overall, China nearly tripled the number of systems on the latest list, while the number of systems in the United States has fallen to the lowest point since the TOP500 list was created in 1993. China is also carving out a bigger share as a manufacturer of high performance computers with multiple Chinese manufacturers becoming more active in this field.
Tianhe-2, which means Milky Way-2, led the list with a performance of 33.86 petaflop/s (quadrillions of calculations per second or Pflop/s) on the Linpack benchmark. Keeping its hold on the No. 2 spot is Titan, a Cray XK7 system installed at DOE’s Oak Ridge National Laboratory. Titan, the top system in the United States and one of the most energy-efficient systems on the list, achieved 17.59 petaflop/s on the Linpack benchmark.
China increased the number of systems on the latest list by 196&, from 37 in June to 109 in November. The United States, despite dropping to its lowest-ever levels, still has the most systems on the list at 200. Europe’s share of systems has also dropped from 141 six months ago to 108, with Asia forging ahead with 173 supercomputers of the world’s top 500 supercomputers, from 107 in June.
