500-fold Increase in Data Flow from SETI Telescope

coondoggie brings us an article from Networkworld about a flood of new data for the SETI@home project. We discussed something similar a few months ago when a new telescope array went live. The vast amount of processing power required to handle the new data is prompting the SETI@home team to make a plea for more volunteers. Quoting the press release: "What triggered the new flow of data was the addition of seven new receivers at Arecibo, which now let the telescope record radio signals from seven regions of the sky simultaneously instead of just one. With greater sensitivity and the ability to detect the polarization of the radio signals, plus 40 times more frequency coverage, Arecibo is set to survey the sky for new radio sources."

      Protein folding is important, however discovery of ETI ranks up somewhere along with; fire, wheel, tools, calculus.

      Find a protein, you change many lives for the better.

      Find ET, and you change the course of the human race forever.

      I will choose what to do with my extra CPU cycles myself, thank you very much. To me, ET is more interesting.

  4. are the cycles really "spare" by atarione · · Score: 4, Insightful

    i was kinda interested in this at one point then when I installed SETI@home i realized that it made my proc max out 24x7 and shoot up to it's load temps (obviously) and of course use more electricity. i decided that I wasn't willing to stress my equipment or pay for the electricity to run this type of software ( I do of course realize you can set the amount of cpu it uses.. but still) I think that all these distributed projects kinda try to gloss over the fact that it isn't free to participate ... and given the $100+ a barrel oil at the moment people that chose to participate should probably be made more aware of what the costs and wear and tear impacts really are.

      The difference between idle and full load power use on processors nowadays is on the order of 20W (though admittedly this is more like 60W on processors like the Core 2 Duo if you have SpeedStep enabled). 50 hours at full load before you've used a kilowatt more energy. Given an average energy price of $0.13 per KWh that's a pretty small amount, on the order of $2 per month. It's still something, but to me the work done for SETI or Folding@Home is at least worth the price of a cappucino every month.

      Processors are also built to run at full load, as long as it holds a good steady temperature (say 50C) you might see its lifespan decreased from 30,000 hours to 20,000 hours. What they're not built for is constant temperature cycling between load and room (off) temperature. Turning your PC off at night will likely have the same affect on its lifespan as constant load does. Again, to me at least, it's worth it. I replace the CPU every 2-3 years anyway and have yet to see one KIA.

      I do think, though, that Folding@Home is a better investment than SETI. Not that I'm not curious about finding life out there, but there are more important things to do here first.

  5. carbon footprint? by Doppler00 · · Score: 5, Interesting

    I'm just curious how much energy the SETI project has used with zero results thus far. Is the amount of resources and time they are contributing to this cause really worth the incalculable chance they get a signal from an alien civilization? Having millions of PC's running at 100% doing pattern searching seems like a huge waste of energy. I'll run distributed clients myself like folding@home that actually have research results. Usually, only during the winter though (since electric heat is my only option anyway).

    Me too. Last time I used it the Linux install involved way too many steps. It is packaged as a 'generic' Linux binary, and left up to the individual to tweak it to fit their particular system. I am quite happy to contribute spare cpu cycles to the project, but at the moment I don't have the spare sys-admin cycles required to setup, configure and babysit the software.

    If they want more people to install it, they need to do something like create a RPM installer and setup a yum repository. If the installation was as simple as 'yum install bonic' plus a simple Python configure script to set the project URL, then ReadHat could/would probably add it to Fedora. Which would mean that 1000's of people would see it listed in the install options, and some of them would probably give it a go.

    The other reason I left was the change in the way that stat were reported. When I started, their website showed a headline figure of number of CPU years in the last 24hrs. To me, seeing that figure increase as the project gained more users was a real incentive to add machines and contribute more to the project. It gave you the warm fuzzy feeling that we were all contributing to what was at the time one of the largest computing projects in the world.

    Now everything is listed as teams competing for 'credits', whatever they are. I didn't join to earn 'credits', I joined to participate in one of the largest collaborative computing projects in the world.

  9. oh I dunno by Quadraginta · · Score: 5, Insightful

    There's a logic error here, I think. By this logic, we should do nothing except the very highest priority thing in our life, and society should pour all of its resources into the very most important priority. For example, we should all live in a thatched hut, eat weeds and grubs, wear the untanned raw skins of animals (or just go naked), and slave 18 hours a day so all our labor and energy can go into....whatever the single highest social priority is...curing cancer, fighting war 'n' injustice, whatever.

    Which is silly. The goal of life is maximize overall satisfaction, not accomplish one single highest goal. It's important to rank your priorities, of course, both as an individual and as a society. But the notion that because A is "more important" than B implies ipso facto that A should get all the resources and B should get none is maximally silly.

    Indeed, it's kind of OCD obsessive to always be focussed on pursuing the Top Goal, the kind of thing that when we see people doing it in practise -- giving up everything, including enough sleep and good nutrition, to, say, play World of Warcraft and become the biggest baddest player -- we conclude they need to do some growing up.

    Fine, I'm burning cycles running a project that may (heck, when it comes to SETI, probably) won't see any tangible results.

    But how is contributing to a project that was the basis for mainstreamed distributed computing any more wasteful than blowing 9 hours a night on WoW? I'd love to see a breakdown of the increased energy usage from a high-end CPU and a good video card vs. a PC that's on anyway and running BOINC when it's idle.

    Screaming "carbon footprint!!" about something as trivial as BOINC is the real waste. Here, I've swapped 80% of the lights in my house for CFL's, and I burned 10 bucks worth of electricity last month (with an electric heater and 4x computers in the house no less!) does make me green enough to spare some processor cycles now?
