Top 500
June's list of the top 500 supercomputers has yet another leader. It seems no one is able to hold the top spot for very long. The new leader is China's Tianhe-2, calculating 34 petaFLOPS. The average of top 10 computers is 10 petaFLOPS. Tianhe-2 is faster than all 500 computers from June 2010 combined.
Overall though, it was a pretty average update. There are 182 new computers on the list and their total calculating power increased by 38%, compared to an average of 36%. Intriguingly, there seems to be a growing divide between the top and the bottom computer. The 500th computer calculates at 0.3% of the speed of Tianhe-2, the biggest difference ever. In past lists, it's closer to 1%. Still even at the bottom of the list, it's faster than the top 500 supercomputers from November 2000 combined.
