Swiss Supercomputer Edges US Out of Top Spot ( 64

There have only been two times in the last 24 years where the U.S. has been edged out of the top spot of the world's most powerful supercomputers. Now is one of those times. "An upgrade to a Swiss supercomputer has bumped the U.S. Department of Energy's Cray XK7 to number four on the list rating these machines," reports the BBC. "The only other time the U.S. fell out of the top three was in 1996." The top two slots are occupied by Chinese supercomputers. From the report. The U.S. machine has been supplanted by Switzerland's Piz Daint system, which is installed at the country's national supercomputer center. The upgrade boosted its performance from 9.8 petaflops to 19.6. The machine is named after a peak in the Grison region of Switzerland. One petaflop is equal to one thousand trillion operations per second. A "flop" (floating point operation) can be thought of as a step in a calculation. The performance improvement meant it surpassed the 17.6 petaflop capacity of the DoE machine, located at the Oak Ridge National Laboratory in Tennessee. The U.S. is well represented lower down in the list, as currently half of all the machines in the top 10 of the list are based in North America. And the Oak Ridge National Laboratory looks set to return to the top three later this year, when its Summit supercomputer comes online. This is expected to have a peak performance of more than 100 petaflops.

    Read the summary, it was bumped out of the top 3 to become #4.

    • If only we had a number representative of a thousand trillion...


      With the two Chinese supercomputers and one Swiss system occupying the top of the rankings, this is the second time in the 24-year history of the TOP500 list that the United States has failed to secure any of the top three positions. The only other time this occurred was in November 1996, when three Japanese systems captured the top three spots.

  • the Swiss just copied Calipari
  • NSA had no comment.

  • Trump's home PC that he browses Fox "News" on for non-fake news is more powerful than this Swiss PoS. His PC's the greatest, has the bestest Interwebs and most ultraflops.

    Top spot != Top three. Is it too much to ask for an accurate title? Clickbait trumps accuracy? I can't think of another reason how this title could have slipped through.
  • This Piz Daint is efficient, too, consuming less than 30% as much power as the Opteron-based Titan. TaihuLight is still very, very impressive, though the new one at Oak Ridge should top it.

    Yeah yeah I know, named after a mountain.

    But I would like to see a supercomputer named Deez Nuts.

  • The name of the supercomputer "Piz Daint" is extremely offensive in many Europen languages.
    But it looks like the owners don't care.

  • I think a far more interesting article would be what are these systems being used for on a day-to-day basis?

  • I think we'll be okay. The XK7 will run AOL just fine for Rick Perry.
