SETI@Home Transitions To BOINC 263

Posted by timothy from the get-your-mind-out-of-the-stellar dept.
SeaDour writes "The team at SETI@Home have finally released their highly-anticipated new client software based on the BOINC (Berkeley Open Infrastructure for Network Computing) software platform. This new platform promises transparent version upgrades, more efficient work unit distribution, and the ability to seamlessly integrate other distributed computing projects that are also using the BOINC standard. For now, SETI@Home is allowing both the Classic and BOINC clients to run, but eventually they will shut down the Classic data server and force everyone to upgrade. You can read more about the transition here."

        Folding at Home [stanford.edu] seems to be another distributed computing project, just like SETI. I haven't RTFA-ed, but the original post says that BOINC will allow multiple distributed programs to run.

          Well, there are a number of ways she could (theorhetically) be helping by working as a psychologist, though there is certainly no guarantee.

          * If she treats children she might prevent those children from becoming abusive to their own children, ten years down the line. Or she might prevent them from becoming rapists.

          * If she works in social services she might identify children who are being abused and put an earlier stop to it.

          * Even if she doesn't help prevent it, she might be able to help repair the damage in the aftermath. Just because she's making money from it doesn't mean it isn't still a worthy cause.

          That said, I've never been impressed with what I've seen from the field of psychology. I do think that just talking to someone who is genuinely interested in helping you work through your problems is helpful though.

      The old version of SETI@Home used the COSM project as a base. (COSM is an offshoot of the distributed.net system, supposedly the "next generation".)


      Replacing the transport mechanism - in a well-designed system - would be a nothing thing. It's just the means of ferrying blocks of data around, it isn't actually necessary for SETI@Home to know any of the internal details.


      This suggests SETI@Home - and possibly COSM - were not as well-designed as all that. Interesting to speculate. COSM isn't progressing, as far as I can see, which may also be a reason SETI@Home moved away from it. It looks like a dead project - a pity, as it had some great ideas - and so any bugs wouldn't get fixed.

Although you can argue that there is a single point of failure because the workload server could be hacked and transfer malicous data to the clients, it is a scenario IMHO not very likely because: a) the workload server has to be hacked, b) it has to stay so for a longer time to have any effect and c) the client software must have a buffer-overflow-like flaw.

    Will the format of input and output files change?

    Yes. The new format is XML-like (though not legal XML).

      Sure, XML is nice to represent hierarchical structures ("filesystem in a file" - like the old IFF for Amiga). A good idea for the web, for office documents etc.

      But XML does not provide information about how to interpret a document (only how to parse/validate it formally or render it in certain, rather special circumstances). The logic to work with and interpret the data still has to be implemented somewhere... interoperability goes only so far as to the repr

    I had heard about the eventual switch-over some months ago, but never found the time to play around with the beta, so I took the opportunity now to install the client and check it out.

    On Mac OS X, all went well, and my PowerBook is munching on it's first unit, fans spinning. However, when I tried to start the client on a Sun box at work, it failed with "ld.so.1: ./boinc_3.18_sparc-sun-solaris2.7: fatal: libstdc++.so.3: open failed: No such file or directory." A quick Google confirmed my suspicions: the client is linked against the GCC stdlib, which is not a standard part of Solaris. Now, that's easy enough to fix if you've worked with Solaris before: just go to sunfreeware.com, and find a suitable binary package to put on.

    However, someone not knowing about Solaris, GCC, and sunfreeware.com might be a bit stumped. And the boinc/setiboinc boards reveal that quite a number of beta testers are confused about this, not only on Solaris but also on Linux. It's not completely obvious which GCC/libgcc packages contains libstc++.so.3 (as opposed to .2.x or .4.x).

    The real kicker is that I couldn't find any hint of this problem or a solution on the site. I probably looked in all the wrong places in the last half hour... And I couldn't find a feedback form or email address either. This definitly needs to be improved if they want people to move over to boinc.

    This may very likely be the beginning of the end for SETI@Home. One of the attractions of SETI@Home for many people is the excitement of tracknig the counter of the number of work units completed. In contrast, the new BOINC-based system has a ridiculously complex [berkeley.edu] and unintuitive "credit" system that users are very unlikely to find compelling.

    I guess this just shows that every project, even a non-commercial one, eventually needs to have someone with some marketing sense if it wants to continue to thrive.

    • While you might be right, I hardly believe that a large number of users are running their computers 24/7 just to appear on a semi-obscure top 100-list.

      Also, I followed your link and I like the new system much better- it awards credits based on CPU time/clock rate instead of just number of work units completed. Thus one credit will be more uniform across all platforms. What's wrong with that?
      • Thus one credit will be more uniform across all platforms. What's wrong with that?

        It makes perfect sense from a techincal perspective. However, it's harder to understand, and therefore less compelling, and therefore less likely to attract new users.

    Boinc is more than just an updated Seti@Home, it's a generic delivery platform for distributed projects. That means you, yes you, can develope a BOINC app [berkeley.edu]. Just gather some people to run it for you and compute away without needing any approval from the guys at Berkeley. Basically the participants enter a project URL into the BOINC application, the program then downloads your code and the crunching begins. BOINC handles all the network, workunit, results, distribution, security, versioning etc. issues for you.

    Participants can even choose to split their resources among several projects, say, Seti@Home and Folding@Home. Another thing that will also be used in the new Seti@Home is that you can have clients participating in the same project working on completely different computation sets. For example, clients that have proven themselves to have a fast workunit turnaround time and a long history of participating and that have a gigabyte or more of RAM can be given special tasks that would normally be impossible because of the high number of griefers on the net.

    Lets see what we can cover:

    BOINC isn't nearly as usful to society as Folding@home, AIDS research@home, help feed starving disabled puppies in war torn african nations@home, etc.

    BOINC != Seti@Home. BOINC is a step up the ladder from Seti, it provides the infrastructure for multiple projects. *you* choose the project to attach yourself to and contribute time to. In an ultra-perfect hippie world, Folding@home would use the BOINC infrastructure. Instead you get to help out who you want.

    I ain't trustin no Berkeley hippies to silently install no black helicopter, tinfoil hat disablin' technology on my system.

    Then don't use it. If you ran seti, you really had no way of knowing what was coming down the pipe now did you? You opened up a nice big gaping connection into your system while trusting that the work units weren't poison pills and that Berkeley's infrastructure hadn't been comprimised. Run the client on a non-critical machine, put it outside your firewall if it makes you happy.

    Scientific progress goes BOINC!

  • I looked at the site, but wasn't able to find anything related to SMP-enabled computers. One of the major downsides of SETI classic was, in my opinion, the fact that it wasn't multi-threaded or SMP aware. Thus, on my dual processor machine, I had to run 2 copies at the same time in order to use both CPUs. That also meant I had to fix each process to a CPU, which doesn't lend itself to the most efficient thread management by the OS.

    So, is BOINC multi-threaded? Can it use more than one CPU effectively?

    In the hopes that someone working on the SETI@home client reads Slashdot, I am posting my bug report about the new BOINC SETI@home client here. I tried to post a bug report on their Windows Client Forum [berkeley.edu], but the authentication routine failed to recognize my account ID when I copied and pasted it from the e-mail message I had just received. (If you don't yet have a BOINC account, it looks something like 213ed9ba2da1696f77b0d0fa3165a3ab, but no, this is NOT my real user account.)

    Anyway, enough preamble. Here's the problem:
    In the Work tab, when I right-click on the currently-running work unit, the context-sensitive menu displays one option, Show Graphics.

    When I select Show Graphics, a window pops up, the entire contents of which is black. At this point, my Windows 2000 SP4 computer freezes. CTRL-ALT-DEL doesn't bring up the Windows Security window. CTRL-SHIFT-ESC doesn't bring up the Task Manager. I can't move the mouse. The keyboard is completely unresponsive.

    Being a sucker for punishment, I sent a non-maskable interrupt to my CPU, and rebooted the machine. Then I tried the exact same steps, and got the same results. Yup, this bug is repeatable.

    So is the new client ready for prime time? Um, not really. Add the insult of the website not recognizing the account ID that it gave me to begin with and I'd say this program should stay in beta a while longer.

    A final note: If you happen to be one of the programmers for the client, and know why this problem is happening, reply here. I'd appreciate a reply.
