Lost WU's with two (slow) machines

    Hi there,

    I'm contributing to Team 3446 now for half a year or so with my iBook and G3 B&W. A marginal contribution in the face of these dual G5 giants in our team, but nonetheless... Every WU counts.

    Last weeks I have problems in getting points for my work. In most cases, the production is uploaded nicely, but it won't increase my point total. Last time, the production of my G3 failed to upload at all.
    That's a pity.
    My question is: what could cause this? Both machines have machine ID =1 and work from the same router (i.e. same IP). Could they interfere with eachother or something like that?

    Can't be more specific, regrettably since I do not know the innards of the process.

    The fact that both processors are under the same router should have nothing to do with it. When each computer downloads a unit, some kind of code is written within the WU, to keep track of it. So when it uploads it back it knows that it is a unique work unit.

    I don't remember where I read this, but I know they do something to protect the WU's and your points.

    I also couldn't say why it's doing what it's doing. Someone else will have to tackle that problem.

    He Bram,

    I had the same last week with my G3 B&W. In the text of the WU it said that it could not connect to the server. The server was too busy. But I looked at my name at the scorelist at Stanford and the WU was counted, only didn't got any points for them... Now I looked again, but haven't send any other WU in. I have received points and it also counts another WU!

    Groeten uit Den Helder!
