    We can do this, however I see you are with SETI.USA, the team founder at BOINCstats is "Team SETI.USA" so the person in charge of that account could do it for you, but I don't mind setting it up, do you have a particular date in mind?

    This challenge starts in around a week, if we are going to load up and bunker, I'd say tomorrow or maybe the day after, deadline for the work units are 7 days.

    Are not able to partake in this one Andy?

    No it didn't, maximum my machines can get is 800 tasks each, worked out I'd have ran dry 1-2 days before the start so I decided to start again, should have enough for Fri morning now :)

    Thanks :)

    Could have been better though, timing wasn't perfect, plus I only got enough work units for 4 days because of the 100 work units per core limitation, which I've since found out (by lurking in the TSBT forums :)) I could have got round with an app_info & client state tricking the server into thinking I had more cores that I actually have.

    May the forth be with us !

    Just over a day to go and unless the french have something up their baguettes that's where we should finish :)

    Will be interesting to hear from Carlos how many WUs are left to do when it's all over but I'd suggest he just ask zombie to keep his machines running for another day or two to get them completed :p

    Sorry, I am overseas.
    We had to extend the boundary to q=2700M. Still 100k wu's to process. At this stage it is very difficult to get right maximum "q" because we are getting less relations than expected to start next stage, the filtering and then the matrix build.

    Okay, enjoy your holiday/work trip :)

    Just so you know your audience, I have absolutely no idea what "it is very difficult to get right maximum "q" because we are getting less relations than expected" means :confused:
