    Hello all.

    I am new here. I started F@H eleven days ago and still have not completed a WU, I believe. So I looked all this forum to see what might be going on. I think I may be having some of the same problems that wdlove and Sparky's had earlier.

    I have F@H installed and running (for eleven days now) on my iMac G4 800MHz.

    Okay after reading thru this forum and checking my system here is what I have observed.
    • There are two instances each of FAHlog.txt, client.cfg, and Fahcore_78.exe on my drive, one each in one of two Folding folders.
    • When I look at Activity Monitor, there are two Fahcore_78.exe running and one instance of Fah5 running.
    • One of the two folding folders in named Folding@home and the other is named F@H1.
    • The Folding@home reports 75% completion of protein p888... The F@H1 reports 45% completion of protein p247...

    Is this normal? Or is something wrong?

    Sounds like you have the script running for a dual processor machine on a single processor iMac. You should certainly only be crunching one protein at a time on that computer.

    So then, how do I correct the situation?

    What shall I do now? Just let the current jobs finish? Or kill them and start over?

    If you are running mc68k's folding script from the terminal, open up terminal and type rid. This will uninstall all the folding scripts and current WU's. Then download and install the single processor script. It's the first DMG file listed here

    If you are using a different folding client I can't help you but maybe one of the other teammates can...

    or only type rid2, I believe that get rid of only the second folding app.

    If I leave it the way it is now, is it hurting anything, or is it just taking longer to complete?

    Also, what exactly is one WU? One completed protein?

    Is twelve days on one protein normal? What is the average?

    It will dramatically slow your folding down to let both continue to run and it actually might screw both of the work units up. Not sure how, but I suppose it's possible for data to be corrupted.

    One Work Unit is one protein. Every individual Work Unit has points associated to it. If you rank teams based on points, MacRumors is 22nd. But we jump all the way to 16th or so if you rank teams based on the number of WU's completed.

    As for how long it takes to complete a WU. Well it depends on the WU downloaded, it depends on the processor type, it depends on how many other apps you have running, etc. 12 days isn't out of the question, but you'd likely go through them faster if you were only running one instance. For example, my Dual 2.0ghz G5 takes about 8.5 minutes per frame on a 400 frame tinker WU. Some machines can take as much as 40-80 minutes per frame. At 40 minutes a frame, that's over 11 days.

    I'd suggest you try what Dreadnought wrote. Type rid2 and see if it eliminates the second instance you have running. Otherwise, wait until the one that is closest to completion is finished and then use the rid command and install the single processor version.
