Interview with SETI@home Director David Anderson

CowboyRobot writes "ACM's Queue magazine interviews David P. Anderson, a research scientist at the U.C. Berkeley Space Sciences Laboratory, who directs the SETI@home and BOINC (Berkeley Open Infrastructure for Network Computing) projects. SETI@home uses hundreds of thousands of home computers in the search for extraterrestrial intelligence. FTA: "volunteer computing arose because projects such as SETI@home needed $100 million worth of computing power but didn't have the money. But there's no free lunch--a project must give participants something in return for their computer time.""

You use the number ONCE for each project on each computer that you register. Let's say the average user runs one, maybe two projects on a single computer. You have to put it in once to sign in on the website, and the site will remember it for you after that. So the average user has to put in the string a total of four times (2x for each project). It can easily be copy/pasted from your gmail. What's so complicated about that?

      BOINC automatically caches work, so you don't have to be constantly be connected to the internet for completed/new workunits. That didn't come with the stock install of the old SETI client. You had to add it on with another program.

      The main benefit of BOINC is the ability of any other project to use it. Without it, would Predictor@home, Einstien@home, or BURP even be in existance? ClimatePrediction.net thought it was good enough to switch over.

      As for the seamless running on other computers, BOINC added a remote administration feature starting after version 4.19. You can connect to any other of your computers that run BOINC and use the same interface to administrate them as you would on that computer itself. You don't even have to be at your parent's computer for anything past running the installer and adding a list of IP's allowed to connect.

      In my opinion, the benefits far outweigh the claimed losses.

What they are really doing is removing the enormous cost (enormous even after its been reduced from a direct super computer) of setting up a distributed computing network, up until boinc it was tons of different standards that each in house dev team had to make from scratch. boinc is a system that lowers the cost (in terms of time and knowledge) to enter the distributed market.

    This is a mostly good thing, unless you have some n00bs like BURP (rendering project) that make a bug that nukes your local machine account info.

Now, it would seem to me that a system like boinc (but not exactly boinc, because I think it's not allowed for commercial use) would be financially a far better deal. Just give the 'users' some mild financial gain, and they will have a userbase by the millions in no time, while for the company itself it would still be cheaper then if they had to pay for regular supercomputer-time.

  63. Probably Virgo, maybe towards Libra by RedLaggedTeut · · Score: 1

    It would be rather easy to find the other side of the sky, since it is exactly opposite. The sky is pretty static(as shown by the zodiac signs) because Earth is not moving much relative to the rest of the galaxy, at least not considering the distances involved.

    Well I took a look and that would give Virgo, maybe a bit towards Libra as the source. Virgo has several interesting and a few close(10 lyrs) stars.

  64. Not the same everywhere. by Burz · · Score: 1

    That may be common on some BOINC-type projects, but I've found that people crunching for ClimatePrediction.net to be more of the concerned variety.

    There is still some emphasis on stats, but overall the activity surrounding the related Open University course and discussion of climate change and ecology tend to eclipse competition for its own sake.

    CPDN is the most demanding distributed computing research project I've seen and narcissists fall by the wayside pretty quickly. What we COULD use are more geeks. ;-)

    So to the over one hundred thousand innocent Iraqi people who have been murdered since the invasion, you are saying to them "no life is better than life under Saddam?"

    No one seriously believed the 100,000 number other than the big media outlets out to get Bush at all costs. Check out this analysis at Slate.com - not what one would consider a Bush-friendly source. It's statistics at its worst.

    A fact-based, yet still not Bush-friendly source is iraqbodycount.net. Their number is 25-28K.

    Now, clearly this is tragic. But consider it in perspective. This isn't Eden where we went in and started shooting up naked people eating fruit. These people were being killed to the tune of 300,000 over the previous decade, where the government sponsored rape rooms for wives and daughters of dissidents, killed political opponents and underperforming athletes by tossing them into "people shredders" and flat-out poison gas attacked its own citizens who stepped out of line. These murders are documented and/or verifiable from excavation of the hundreds of mass graves around Iraq where they bulldozed in the bodies.

    Now, consider the current deaths occurred during a time of actual War, that the people have been liberated, and that the insurgents have to import terrorists because the Iraqi people are not sympathetic to their cause. Then please try to restate your case how the Iraqi people were better off under Hussein.
