    MilkyWay@Home

    New BOINC project MilkyWay@Home

    Not too many wu's available just yet, I've just grabbed a few to try it out whilst Cosmology is unavailable...

    team is http://milkyway.cs.rpi.edu/milkyway/....php?teamid=23


    xml is exported, so stats are at http://stats.free-dc.org/new/projpage.php?proj=mil

    They are also here for anyone wanting to take a peek at the newer stats being written under zope....

    let's go looking for top ten and beyond.

    New stats look great Bok :

    it looks like this will be a very long running project, so will set one box plugging away for ever and a day.

    I will Finish up other work and swap over

    The work units only last ~3 minutes each, so I'm sure it will be difficult for the server to keep up, kinda like Eon, good thing to have running along side something else Boinc related.

    Bok your stat page for this project has the wrong link on it http://milkyway.cs.rpi.edu/milkyway/stats/
    it should be http://milkyway.cs.rpi.edu/milkyway

    Note that I'm getting quite a few wu's crash out, leaving BOINC spinning until I close the error window on each machine....

    Better check those.. Boincview shows each wu up in yellow in these cases..

    Bok

    *EDIT* seems they are aware of it and it might be fixed now...http://milkyway.cs.rpi.edu/milkyway/...read.php?id=52

    Ya same here since late last night

    Also the scoreing on this project is all messed up

    This computer gets 1,291.38 points for doing only 159 jobs GenuineIntel
    Intel(R) Xeon(R) CPU X5355 @ 2.66GHz [x86 Family 6 Model 15 Stepping 7] Microsoft Windows XP
    Professional Edition, Service Pack 2, (05.01.2600.00)
    And I see it is repeatably

    We only get 1 to 3 points on norm NOT RIGHT

    some info just posted on the message boards by the project admin...

    I'm going to be starting a few more searches now that'll hopefully run while i'm out of town until saturday. the results are looking great

    Right now we're looking into two different things:

    1. The effect of the asynchronous return time of work units on the quality of the genetic searches we're running. If you'd like to read more about the asynchronous genetic search we're running, we have some papers we sent out recently to workshops/conferences detailing the search -- but we only had results using the new BlueGene supercomputer here at RPI, and our local RPI Grid of clusters.

    The papers can be found here:
    http://www.cs.rpi.edu/~deselt/desell..._ppam_2007.pdf
    http://www.cs.rpi.edu/~deselt/hcw2008.pdf

    What we're hoping to do with this information is determine what effect a really heterogeneous computing environment has on our asynchronous genetic search, and figure out ways to optimize the search for these types of environments.

    2. The astronomy program we're running currently calculates an integral over the wedge of the sky we're modeling. Since it's not possible to actually integrate the function we're interested in, we have to calculate the integral the old fashioned (and expensive way) of calculating a bunch of points and calculating the area between them. The next few searches we plan on doing will calculate the integral with varying accuracy - so expect work units of varying times (probably 8 minutes to over an hour). With these results we'll be able to figure out what effect the integral accuracy has on the rate our genetic search converges to a solution, and what effect the integral accuracy has on the quality of the answer.


    Some other things that we have in the works is that i've been working on an asynchronous particle swarm algorithm to use (as opposed to asynchronous genetic search). For a brief overview of what particle swarm optimization is, wikipedia isn't too shabby: http://en.wikipedia.org/wiki/Particl...m_optimization . We'll be able to contrast and compare these two searches, which should be interesting.

    Also, we're using the results to compare doing this work on BOINC to the BlueGene supercomputer at RPI. Who knows, with enough participants in the project -- you guys might beat out the 7th fastest supercomputer in the world! (see: http://www.top500.org/lists/2007/06 )

    Well if anyone can do it Free-DC can

    To stop BOINC hanging with an error >> control panel >> system >> advanced tab >> (at the bottom) error reporting >> disable & don't notify

    OK, I'm sucked into yet another priceless project!

    This gets one core, haven't decided which yet. Currently running on one half of AMD 6000 X2, may switch to laptop.

    BOK, you can save yourself some interruptions by, on that window, checking Don't Notify Microsoft. That is, unless you'd like your error reports piled on top of the billions of other unregarded, unwanted and uninspected error reports from the rest of the M$ world. This is the switch that brings up the neat little window, "Would you like to send a report of this error to Oregon?" or some such. Waste of time.
