Top 500 Supercomputer List for June 2014

A new list of the Top 500 Supercomputer Sites has just been published and for the third consecutive year the most powerful designation goes to the Tianhe-2 supercomputer at China's University of Defense Technology with a performance of 33.86 petaflops delivered by its 3.1 million Intel Xeon cores.

A few highlights from the list:

  • Total combined performance of all 500 systems has grown to 274 Pflop/s, compared to 250 Pflop/s six months ago and 223 Pflop/s one year ago. This increase in installed performance also exhibits a noticeable slowdown in growth compared to the previous long-term trend.
  • There are 37 systems with performance greater than a Pflop/s on the list, up from 31 six months ago.
  • The No. 1 system, Tianhe-2, and the No. 7 system, Stampede, use Intel Xeon Phi processors to speed up their computational rate. The No. 2 system, Titan, and the No. 6 system, Piz Daint, use NVIDIA GPUs to accelerate computation.
  • A total of 62 systems on the list are using accelerator/co-processor technology, up from 53 from November 2013. Forty-four of these use NVIDIA chips, two use ATI Radeon, and there are now 17 systems with Intel MIC technology (Xeon Phi). The average number of accelerator cores for these 62 systems is 78,127 cores/system.
