Thread: Amicable Numbers GPU App

  1. #21

    Re: Amicable Numbers GPU App

    With a little help from the admin i figured out why my times sucked so bad.

    My XEON CPU's are too slow to keep the GPU feed with just 1 WU and reserving more CPU's does not help as it appears the GPU app is single threaded.

    I am now running 3 WU's on my 1070 and 4WU's on a 1080 and it appears to be working correctly now.
    each WU gets its own CPU thread.

    360 Xeon Threads - GTX 1080 - GTX 1070 - BFL Monarch 700 - OrangePi+ 2E - RaspberryPi 3b+

    That's a really good thing to know KB since I have similar Xeon machines. My single GTX 1080 is running in a 4.2G I7 and a single WU keeps the GPU at 100% load. Another intersting thing is the I7 is PCIe 2.0 and your Xeon MB is PCIe 3 so it should be quicker.

    Why don't you throw 20 GPUs in each box? HERE

    Having to run 8 WU per 1080 to keep usage up now.

    FYI my xeons are downclocked to 1.9GHz due to using AVX.

    Yes, too complicated to build a co_proc, for my feeble mind!
