Tianhe-2 notches up 30.65 petaflops during benchmark test
China scaled the supercomputing summit in late 2010, when a 2.507-petaflop machine named Tianhe-1A (or Milkyway-1) was ranked as the fastest supercomputer by TOP500, which publishes a list of the fastest 500 supercomputers twice a year. Its stay there, though, was brief, lasting all of six months. But if you think it was just a flash in the pan, the Chinese National University of Defense Technology (NUDT), the organization which developed the Tianhe-1A, is building the Tianhe-2 in order to prove you wrong.
How do you make the most powerful supercomputer in the world even faster? It’s simple, really. Just keep adding components! When Japan’s K supercomputer assumed the top slot back in June, it did so thanks to a team of 68,544 CPUs working in tandem to achieve a maximum LINPACK performance rating of 8.162 petaflops. Since then, the last of its 864 racks have been installed – and that extra firepower has boosted K’s performance over the 10 petaflop barrier.
