    Something seriously wrong with my Collatz?

    I switched my GPUs to Collatz last night, and the nVidia card is pumping the SOLO_Collatz out awesome - around 32 mins each.
    However, something is up again with this HD 5870. I noticed I got OpenCL collatz WUs on it, so maybe that is the problem? They are NOT Solo_Collatz, just the regular ATI Collatz is what I have checked in my preferences (I couldn't get the solo ones to work either) and when I check my computer, I've got a Collatz OpenCL WU that has been running for 7 hours and 15 mins, and it's only 29% completed! Shows my GPU load at 98%. If I suspend it and try another, one, I get the same slow results judging by how slow the % complete goes up. Wonder what's going on?
    Do you guys think I need to change the drivers or reset the project on this computer or ??? I'm out of ideas...
    Thanks for the help.

    Good luck. Unfortunately, I can't have both CAL and OpenCL apps and pick and choose. In theory DA's logic is supposed to run a couple of each and then go with the faster app after that. In reality, his logic is overly complicated and sucks. So, even though the CAL app has a higher flops estimate than the OpenCL app, it still sends out OpenCL WUs. Even after they are completed and the CAL app is 8x faster, it still sends them.

    I used to have logic so that only HD 7xxx GPUs would get OpenCL apps, but after the server upgrade required to support Intel GPUs, that logic was lost. If I put it back in, then only HD7xxx GPUs can run the solo app as it doesn't have a Brook+ counterpart. So, I'm kind of between a rock and a hard place since the BOINC logic doesn't work and the scheduler won't let me make it work unless I can do app specific scheduling. At present, it is controlled by the plan class but ignores the app names.

    If your collatz lasts for longer than four hours then contact your doctor.
