China Stays Atop the Latest Top500 List

Swiss system clocks in at Number 6, and Titan holds on to the second spot.

The latest edition of Top500 list of the worlds fastest supercomputers was announced on Nov. 18 at the SC13 conference in Denver Colorado. The new list had few surprises, at least near the top, with 9 out of the top 10 systems returning from the June 2013 list.
The massive Tianhe-2 (Milky Way 2), which is owned and operated by China's National Super Computer Center, led off the list, delivering 33.86 petaflops/s, compared to 17.59 petaflops/s for the runner-up Titan system, which is operated by the US Department of Energy's Oak Ridge National Laboratory. The only new arrival in the top 10 is the Piz Daint, a Cray XC30 system owned by the Swiss Scientific Computing Center.
According to the announcement at, "The total combined performance of all 500 systems on the list is 250 Pflop/s. Half of the total performance is achieved by the top 17 systems on the list, with the other half of total performance spread among the remaining 483 systems."
The US has the most computers on the latest Top500 list with 265. Asian countries account for 115 systems, and 102 of the Top500 are in Europe.
