Researcher Discusses iPod Supercomputer 108

Posted by ScuttleMonkey from the melts-in-your-hand-not-in-your-rack dept.
schliz writes to mention that in a recent interview with ITNews researcher John Shalf explained the purpose and some of the technical details of the newly-announced "iPod supercomputer." "Microprocessors from portable electronics like iPods could yield low-cost, low-power supercomputers for specialized scientific applications, according to computer scientist John Shalf. Along with a research team from the US Department of Energy's Lawrence Berkeley National Laboratory, Shalf is designing a supercomputer based on low-power embedded microprocessors, which has the sole purpose of improving global climate change predictions."

        I think you're confusing this with the Zune super computer... and it doesn't "share" it "squirts [portableplanet.co.uk]"
        • REDMOND, Seattle, Wednesday (UNN Technoporn) -- Microsoft CEO Steve Ballmer today announced a new era at the Seattle software company, announcing their entry six^Wnine^Wtwelve months hence into the cell phone market with the exciting new Zune Z-Phone, to finally get the company properly into the rapidly changing digital media landscape.

          Ballmer, speaking to a group of trained-monkey analysts and cynical bloggers at the company headquarters today, unveiled mockups^Wprototypes of the Z-Phone, which combines the Zune music player (with wifi for "squirting" songs), a CDMA cell phone, a PDA, an eight gigabyte hard disk, a camera, a laser pointer and a bottle opener into one semi-portable device. It will also allow you to "squirt" music to and from your Windows Vista Service Pack 1^W2 Media Center computer.

          The product underscores the shift the company has attempted to make in recent years from an office supply company to a consumer electronics darling as it aims not to become utterly obsolete in the digital future. "And even Linux fanboys admit our hardware is pretty nice," Ballmer said before the somewhat sullen and cynical crowd. "It's definitely the best music player we've ever made."

          Ballmer called the Z-Phone a revolutionary device that will leapfrog current technology. He said the company expects to sell about 100 million of them next year. "Maybe two hundred million. This is so the coolest music player ever." Unlike the MP3 player market, which the iPod has dominated even with the entrance of Microsoft's Zune two months ago, the cell phone market is much more fragmented. "There is not one device that everyone buys," said completely independent analyst Rob Enderle, "but this fabulous device should trounce all comers. I've ordered three already in anticipation."

          Weighing in at only 15 ounces (425 grams), with a 5-inch 640-by-480 pixel screen, the $498 (with three-year $80/month contract) Z-Phone, a rebadged version of the LG Smart Display from 2003 with new firmware, looks like a Classic Brown Zune (to come in mission, chocolate, corduroy and meconium) with a phone touchpad in place of its imitation scroll wheel. It runs Windows Mobile, Pocket Internet Explorer, Pocket Microsoft Office, Pocket Solitaire and Pocket Pool. MSN will supply e-mail, mapping, search and other Internet services to the Z-Phone. It also features an amazing 1.3 megapixel (300,000 pixels interpolated) black and white camera. Battery life is estimated at up to four hours in Microsoft tests.

          To better work with its content partners and ensure that you, the user, can rest safe in the knowledge that the artists and their representatives have been paid properly for all their hard work, Microsoft has limited "squirtable" songs to encrypted WMA files purchased from the Zune Music Store, which can be listened to three times or within three days before automatically being deleted from both the Z-Phone and the Media Center computer. Songs may also be "squirted" between two Z-Phones (though not the original Zune) if both are registered with Microsoft as being linked to that installation of Media Center. Users are advised to purchase Microsoft Zune Secure Headphones ($129), which encrypt the signal between the Z-Phone and your ears, as playback quality is degraded on conventional "analog hole" earphones or when playing back unencrypted MP3 files. Phone calls may be made to or received from any number on the network carrier you bought the Z-Phone from, with only a 99-cent charge for humming a song to someone you call or are called by on the phone or ten cents per use of the camera, laser pointer or bottle opener. Microsoft will also pay $20 from each Z-Phone sold to Universal Music. In addition to the ability to "squirt" songs, the user may "squirt" his calls, which are stored on Microsoft Zune Live servers and cost $40 per month to access.

          In other news, Ballmer said that Microsoft had reached over 600 music downloads since introducing its Zune Music Store, selling over 70 songs a month. To keep those numbers rising, Ba

    There's a famous quote about supercomputers that says that supercomputers are really good memory systems, with a bit of CPU tacked on. The hard part isn't adding more MIPS -- we've done that with the massively parallel connection machine -- or even increasing speed. It's about shuttling the data around the computer efficiently so that all ALU's are constantly fed. During the cold war, Control Data had a supercomputer that came in two variants -- one for domestic use, one for export. The difference between them? Same ALU speed, but the domestic one had a scatter/gather memory access capability that sped up big matrix operations.

    I read the article, and they are planning to have special CPU chips fabbed: CPUs tailored specifically to the needs of climate modeling. I guess this will provide the lowest possible operational cost--the least electrical consumption and heat dissipation possible to solve their problem.

    Not just the title is misleading but the idea associated with it. Last time I checked (ok, that was a while ago), iPods came with ARM7 cores clocked at 80 MHz. Thing is, these CPUs don't have a floating point unit, so unless they write they weather simulators in fixed point arithmetic (lol, right) or go ahead with software floating point emulation (which would slow things down several times) they're not going to use these, they'd rather use more sophisticated stuff like ARM11s or Cortex A8s.
    • The ARM7s are RISC CPUs, they do only a few instructions very fast and efficiently. That means that if you want an FPU you include one in software and if you don't then you also don't have to pay for one or have to power one saving you a pack of cash.

I can't think of any reason for a software FPU to be tremendously slower, sure there's a bit more overhead but on the other hand a RISC processor will typically execute instructions far faster then a CISC.
