    i just loaded this project on my pentium m 1.7ghz laptop... after 15 min of work est time of completion is 2737 hours...

    This also seems to be a BBC project... diffrent then CPDN i think.. per their page there is no free-dc team yet..

    Thanks,
    Ryan

    :::EDIT::: looks like people on their message boards are saying not to install their custom boinc client but use the normal one... attach to this project using project url = http://bbc.cpdn.org

    that's what I've done - use bbc.cpdn.org to attach.

    CPDN also uses trickles so you don't have to wait the 1600 hours (or whatever) for points...just think of it as a lot of WUs downloaded at once, it helps

    Joined the Climate Change Free DC team (there was a CPDN one but this is a different project).

    The BBC experiment is running the same models that the main CPDN project will be running in a few weeks time. Or more specifically, the BBC project is running phase 2 of CPDN but phase 2 hasn't been rolled out to the main CPDN project yet - it's coming soon apparantely.

    I read from here http://www.theregister.com/2006/02/1...imate_project/
    The program will take an average home PC around three months to run a climate model from 1920 to 2080. The scientists say it will not significantly affect performance. Allen said the aim of the 500,000 permutations was to get an accurate picture of changes that occurred in the 20th century.

    So for now the BBC project and CPDN are seperate projects? When CPDN goes to phase 2, will it be working on the same data or different stuff again?

    I gather that the CPDN phase 2 will be the same as the current BBC CCE project, but there won't be duplication in the WUs - ie the BBC are getting a block of WUs and CPDN will process the rest.

    I could be wrong though - I'm just picking this up from all the forums about.

    Crikey these WU's are huge !!

    Someone mentioned 1600 hrs to completion, well only if you are using an FX57

    Most PC's are going to take a lot longer than that.

    I run on Linux with just the command line, no X server. So I need the project URL and a key to connect to the project. Anybody know how I get a key for this project ? They seem to assume that everybody will connect through the graphical client.. No "create account" option on the website ?

    One of my clients seems to attract WUs that error out - looking at the results the WUs error out elsewhere...very odd that it's the only one out of 8 clients to do this...
