    Ah, I had not realized that. Thanks for the correction.

    Re: Collatz: Collatz Back Online with Solo Collatz Only

    ecafkid just started crunching and started on Collatz, can one of you send him a message?

    That would be nice one new cruncher to our team.

    No, I'm talking new GPU tasks. I seem to remember before the most recent "Event" the GPU work units used only a small fraction of a cpu.

    I plan to run Collatz for a couple days then move back to Milkyway throughout the POGS challenge. I need every bit of cpu I've got to make a dent there.

    Ah. No. GPU task need what they need, with regard to CPU resources.

    Change the config file. The defaults are such that slow GPUs work OK which means lots of small kernels and therefore more CPU time.
    threads=8
    items_per_kernel=22
    kernels_per_reduction=9
    sleep=1

    I have a different issue. All my mixed GPU systems started DL'ing AMD and nVidia work even though I had prefs set for nVidia only. Ended up using <exclude_gpu></exclude_gpu> tags in cc_config on those boxes. Probably just a glitch in the server.

    F$
    Sure you aren't getting AMD CPU work and nVidia GPU work? The AMD drivers include OpenCL drivers for CPUs. Then again, as OpenCL for CPUs is new, I'm sure it is still pretty buggy. I fixed/changed a bunch of code on the server already just so it would better handle Intel vs. AMD CPU drivers.

    No, I'm sure they were AMD GPU tasks as they pushed my Moo work to the side (Waiting to Run) and started crunching. I figured all the recent changes to the server code might have contributed to the issue so I just used the work around and posted here so you would know.

    Just tested again after removing exclude tag from cc_config. Still getting opencl_amd_gpu work.

    One other thing I noticed, the prefs page on the website....

    Use NVIDIA GPU []
    Enforced by version 6.10+

    Use Intel GPU []

    What happened to Use AMD GPU? <---- Source of problem?

    I'm not going to run Collatz right now as I need to still get to 250 Million on Moo, still about 25 Million to go will take another 30 Days or so at the pace I'm on, no hurry to get there on Moo just want to get there though eventually ... ... Just was wanting to see if the Collatz GPU Wu's would run on my 7970's now, may go for a Billion on Collatz when I'm done with Moo ...

    All my AMD cards are working and earning good credit (although CPU usage is high). Interestingly, my 7790 is outperforming my 5850s by 56% while using about half the power.
