Students Power Supercomputer with Bicycles

Posted by samzenpus on from the those-crazy-college-kids dept.

inkslinger77 writes "A team of ten MIT students powered a supercomputer for twenty minutes by pedaling bicycles. They duly claimed the world record for human-powered computing (HPC). They powered a SiCortex SC648 supercomputer with a Linux cluster of 648 CPUs and almost 1TB of main memory in a single cabinet. The system is low-powered and draws 1,200 watts without needing special power supplies or cooling..."

    One MIT student is how many foot pounds per second?

      Well, assuming a lack of friction or air resistance and perfectly spherical MIT students...

      You must be superhuman. Best cyclists can endure 200 wats for few hours. I could make 200w for 5 minutes (tested on ergometer).

      Actually, you're well wrong. Cycling, like anything else, is about power to weight ratio. Lance Armstrong, in training, could output 6.8 watts per kilogramme, which on his body weight of 74Kg is just over 500 watts. Some of the big fast guys (Tom Boonen, Magnus Backstedt) can sustain really startling outputs for long periods of time. I have a friend who peaks around 600 watts and can sustain better than 400 all day; but on his 102Kg that's only 6 watts per Kg. That's strictly amateur - he's fast for us, but he couldn't compete with the pros.

      There's nothing at all hard about 200 watts. Any club cyclist who can do a ten mile time trial at evens is sustaining 4.8 watts/Kg for half an hour. I can do that, and I'm probably old enough to be your grandfather. I weigh 82Kg, so for me that's 381 watts. And I can certainly do 200 watts (13.5mph on the flat, for someone my weight) for eight hours continuous without difficulty.

    So, the students don't run Linux... they bicycle it instead!

    They should have just gone over to the nearest administrative offices and unplugged all of the CRTs running "screen savers". This would have freed power to run the computer even longer and wouldn't have been as tiring.

    It used to be research.

    Then little errands. Get the professor a coke, pick up his stuff.

    Then acting as tech support.

    Then doing all the prof's work for him.

    And now... running the system by the sweat of your brow.

    We must draw the line somewhere, folks. Free labor has its limits!

    This cannot bode well for graduate students... well... maybe for the chunky among us... but let's hope this doesn't catch on. I can already see profs carried about on the shoulders to and from meetings...

  6. New record? by Titoxd · · Score: 4, Interesting

    OK, so they broke the record for human-powered computing. But what was the previous record? Was there even such a thing as a previous record? How is this new record actually measured? You know that more people will now try to break the MIT mark, and TFA is rather scant on details...
