From PC World: With no change at the top of the latest Top500.org supercomputer list, you need to look further down the rankings to see the real story.
Top500.org published the 49th edition of its twice-yearly supercomputer league table on Monday, and once again the Chinese computers 93-petaflop Sunway TaihuLight and 33.9-petaflop Tianhe 2 lead the pack.
An upgrade has doubled the performance of Switzerland's GPU-based Piz Daint to 19.6 petaflops (19.6 quadrillion floating-point operations per second), boosting it from eighth to third place and nudging five other computers down a place. The top U.S. computer, Titan, is now in fourth.
That's it for changes to the top 10, though, and if you stopped reading there, you might think supercomputer makers had fallen asleep.
But "mid-range" supercomputers are still getting more powerful.
Since November last year, 108 of them have leapt into the rankings ahead of the Chinese computer in 500th place, a 432-teraflop machine built by Sugon in 2015 using Intel Xeon processors. It was in 392nd place last November, and entered the rankings a year earlier in 213th place.
