Distribute Stuff: Cosm Project's CS-SDK 65

Posted by timothy from the hither-and-yon-and-hither dept.
Duncan3 writes: "After almost 3 months of public testing the Mithral Client-Server Software Development Kit is now officially out. The Mithral CS-SDK is a part of the Cosm Project which longtime slashdot readers will remember, and is fully buzzword-compliant with "distributed computing", "peer-to-peer", "file-sharing", and "cycle-sharing" - meaning you can easily build any of those types of applications in a weekend. So I expect to see slashdot readers put out at least 20 projects by next Thursday. The Folding@home project based at Stanford has been running for a couple months now doing protein folding and uses the CS-SDK. You can visit them at and download their client software or OpenGL screensaver for Linux x86/Alpha, Tru64, and Win32." Interesting to see how mainstream distributed computing has become even in just the past 12 or so months. Fold proteins, find aliens, break crypto ... what else?

    You may have heard or Echelon, the worldwide computer system that
    monitors all electronic communications.

    Well, don't believe what the conspiracy crackpots tell you - it does not
    automatically detect messages containing sensitive keywords. Using voice
    recognition software on all the data that's been recorded needs a lot of
    computing power.

    But now you can help. Download the new Echelon@Home screensaver - it
    regularly retrieves recorded conversations from the archives at Menwith
    Hill and, while your computer is idle, scans them for keywords.

    If you want a copy of the screensaver, simply send a message with the
    subject line "Echelon Wiretap" and you will be emailed a copy.

    It doesn't matter who you send it to, we'll get the message.

  • I run LARGE analysis jobs on my workstation, which I would dearly love to foist on the other several hundred computers on our companies network. However, I am using canned stress analysis code (writing my own is not a true option) which I can not modify to take advantage of distributed computing techniques. I propose a program which emulates the hardware and allows NT or Linux or WHATEVER to be installed on it and then goes ahead and distributes work out to other computers as if they were merely more cpu's in parallel with the servers own... Can the boys and girls say 'cluster'? But this time only one cpu is always there, the others check in and out as their screen-savers switch on. Someone just go ahead and write this, I and many others would pay money for this sort of thing!!

    "That's all well and good, but searching ads doesn't require distributed computing. It requires 10 seconds on a 386."

    There are other concerns where the distribution might help. For example, how many ad sites are out there with stale ads? By maintaining your own ad on your own "servlet" app, ads should be better maintained. If you don't want people looking for that used TV you were offering because you sold it, you nuke the ad on your machine. Presto! No more appearing in search results! Compare this with the week or so worth of phone calls in a paper after a sale, or the tendency for people to convieniently "forget" to delete an ad at, say, Excite after it has served its purpose.

    Use of an appropriately flexible format (I work with XML, so I'm biased as some have noted, but whatever works...) can make this a reasonably effective "distributed classifieds", IMUO.

There's no reason source files couldn't be replicated over an entire compilation farm every time they are saved to disk and then when I kick off a build, I could have everything compiled almost immediately.

    The Mithral Client Server Software Development Kit allows developers to quickly and easily write large scale client-server applications including "distributed computing" and peer-to-peer types. Examples of what this will allow you to build with this technology are distributed.net, SETI@Home, Napster, Gnutella, and hundreds of other applications. The example code is an instance of an application that hands out work for the clients to do, then collects the results.

    So will there now be [Number of Projects] * [Number of SETI@home users] users availiable now to run these programs, or will there be [Number of users] / [Number of projects] users, thus giving each project a fraction or the number or distributed computing users?
