Titan Tops Top500 Supercomputing List 52

miller60 writes "The new Top500 list of the world's most powerful supercomputers is out, and the new champion is Titan, the new and improved system that previously ruled the Top500 as Jaguar. Oak Ridge Labs' Titan knocked Livermore Labs' Sequoia system out of the top spot, with a Linpack benchmark of more than 17 petaflops. Check out the full list, or an illustrated guide to the top 10."

    NASA/Stennis Space Center, Mississippi. Used to be in the top 10. they have fallen way behind.

      look at it this way: if they hadn't split their acquisition into 2 separate 391 (Rpeak) TFLOPS systems, they'd probably be good enough for #36.

    Sorry to be pedantic, but "petaflops a second" is redundant -- FLOPS means "floating-point operations per second."

      Maybe they mean the number of anti-fur ad campaigns that somehow backfired per second?

    • I suspect that miller60 enjoys driving his car at 60 MPH per hour.

      Thank you so much. It grated on me so much, I came here to whinge about it. Now instead of being a complainant, I can merely congratulate you and look good. :)

    • Maybe they're measuring the acceleration of it's floating point operations!

      • Man, if it's operating at 17 petaflops per second, just think how fast it'll be by this time next year!

      Go easy on the author. This is politics discussion site, so not all of us understand basic computing terms.

    more than 17 petaflops a second.

    Wait... 17 petaflop per second per second?! How long can it keep that up?

    • For a fortnight per furlong
    • About 1.59 seconds, until it reaches 27.113 petaflops? Then it should decelerate about 0.56 seconds, stabilizing at 17.59 petaflops.

      0 to max in 1.6 seconds, sounds like an awfully fast car^H^H^H machine.

  • Quadrillions of operations per second per second? So these machines only do scalar operations? I thought Linpack was a matrix test =)

  • "with a Linpack benchmark of more than 17 petaflops a second"

    Supercomputers calculate on an accelerating performance curve now?

      Sure. Just the number is wrong. If the top computer does 17 petaflops, and the list is run for about 30 years = about 1 gigasecond, then the average growth is 17 megaflops per second. Actual growth was a lot more in the last year, and less before.

    would have made it onto the June 2000 supercomputer list, and would have made 2nd place in the June 1993 list, both with the CPU alone. At least if Dongarra wrote the Linpack code :-)

    2.3 GHz, 4 cores, 256 bit vector registers, one add + one multiply per cycle throughput = 73.6 GFlop/s theoretical limit; with hyperthreading one should get quite close to that limit. Top 500 in June 2000 was only 44 GFlop/s, 2nd place in June 1993 was 30 GFlop/s.

    Are we in a race to see just how fast we develop AI that will kick our asses? Skynet or the Forbin Project seem to be the goal.

    The obvious question "which are running Linux" is almost impossible to answer. Are they sponsored by Microsoft? However, you can use the "sublist" feature to make a list of the first 500 computers and limit to "Linux" as operating system. The list contains 469 entries, and the first number that is missing from this list is "38".

    Huh.

    So while it will refuse to actually show the OS, the sublisting feature makes it able to wrestle it out indirectly.

Nothing is faster than the speed of light ... To prove this to yourself, try opening the refrigerator door before the light comes on.

Working...
