Japan Supercomputing

Japan Aims To Win Exascale Race 51

dcblogs writes "In the global race to build the next generation of supercomputers — exascale — there is no guarantee the U.S. will finish first. But the stakes are high for the U.S. tech industry. Today, U.S. firms — Hewlett-Packard, IBM and Intel, in particular — dominate the global high performance computing (HPC) market. On the Top 500 list, the worldwide ranking of the most powerful supercomputers, HP now has 39% of the systems, IBM, 33%, and Cray, nearly 10%. That lopsided U.S. market share does not sit well with other countries, which are busy building their own chips, interconnects, and their own high-tech industries in the push for exascale. Europe and China are deep into effort to build exascale machines, and now so is Japan. Kimihiko Hirao, director of the RIKEN Advanced Institute for Computational Science of Japan, said Japan is prepping a system for 2020. Asked whether he sees the push to exascale as a race between nations, Hirao said yes. Will Japan try to win that race? 'I hope so,' he said. 'We are rather confident,' said Hirao, arguing that Japan has the technology and the people to achieve the goal. Jack Dongarra, a professor of computer science at the University of Tennessee and one of the academic leaders of the Top 500 supercomputing list, said Japan is serious and on target to deliver a system by 2020."

  • Down with the capitalist emperors!

  • setting a goal for 2018 or 2019 ?

    Such races are very good for the overall development and progress of computing, as the new technologies that will be developed will eventually be used in desktops and mobile computing.

    There are still challenges like the interconnects and the power draw, but IMHO these are problems that eventually will be solved.
  • But thanks Japan and others for your participation.
  • ...from becoming a hemispheric disaster. [huffingtonpost.ca].
    Even the laughable freeze-the-ground-around-it plan seems to have been hatched to mollify Olympic commission voters [cbsnews.com] who still gave Japan the 2020 games as the 'safe' choice over Istanbul and Madrid.

      The work to prevent Fukushima from being a "hemispheric disaster" already happened.
      • The hemispheric disaster has not happened yet. But until they finish unloading reactor 4 - which won't be until end of 2014, any serious earthquake (a high probability in that area) could cause the precarious elevated rod bundles to crash down and even the best case scenarios, if that happens, are ugly.
        How bad things are after that is still up for debate, but reactor 4 is a clear and present danger.

          Uh huh. You do realize that these fuel rods have already experienced a magnitude 9 earthquake and the "crash down" didn't happen? The "precarious elevation" is not that precarious.

  • China is doing some amazing stuff in HPC, and with homegrown IP.

      Homegrown as in stolen?

  • I think the exascale race will turn out to be a dead end. Tightly coupled calculations simply don't scale. To effectively use even current generation supercomputers you need to scale to thousands of cores, and there just aren't very many codes that can do that. Exascale computers will require scaling to millions of cores, and I don't see that happening. For all but a handful of (mostly contrived) problems, that won't be possible.

    So like it or not, we need to settle for loosely coupled codes that run mos

    • "I'm too busy to research this and form an educated opinion, but I do have time to tell everyone my uninformed opinion."

      Well you can't argue with that, but certainly a whole industry would argue with your assertion.

      • I gather you're new to slashdot? Most people on here have signature quotes like that. They get added automatically to every post. It's not part of the message.

    As an interesting observation, the Bitcoin network has peaked at over 60 exaFLOPS of computational power.
  • Building an exascale computer is all well and good, but we still have to find a way to power the damn thing. How will we generate the necessary 1.21 jiggawatts?

    Computers are ESD sensitive, after all, so lightning is right out. Perhaps a stainless steel frame would help with the flux dispersal...
