The Top500 list, which got updated twice a year at the International Supercomputing Conference, claimed Tianhe-2 supercomputer as the lead in Top500 list. The Tianhe-2 supercomputer, with 3.1 million processor cores has a 32,000 Xeon processors linked with a Chinese interconnect called TH Express-2 and is boosted by 48,000 Xeon Phi accelerator processors for a total of 3.12 million processor cores. Tianhe-2 also got 1 petabyte of memory and consumes 17.8 megawatts of power.
Other highlights from the June 2013 TOP500 List include:
- There are 26 systems with performance greater than a petaflop/s, up from 23 six months ago.
- A total of 54 systems on the list are using accelerator/co-processor technology, down from 62 in November 2012.
- The number of systems installed in China has now stabilized at 66, with 72 and 68 on the last two lists.
- Intel continues to provide the processors for the largest share (80.4 percent) of TOP500 systems.
- Eighty-eight percent of the systems use processors with six or more cores, and 67 percent with eight or more cores.
- IBM’s BlueGene/Q is still the most popular system in the TOP10 with four entries, including No. 3, 5, 7, and 8.
- Total combined performance of all 500 systems has grown to 223 Pflop/s, compared to 162 Pflop/s six months ago and 123 Pflop/s one year ago.
