I been absent from the forums as of late. Been very busy with work, not with rigs, they have been flawless. I have not even thought about my rigs in a couple of months, they take care of themselves (they had a power outage a few weeks ago restarted fine on their own). I have a couple of close mates that I wrote a Linux / Nvida instruction manual for, and they both have been running smoothly for several months as well. Have been thinking about posting but have a commercial deal pending that prevents me from doing that.
Anyways, I am converting one rig to Deep Learning AI Rig via CUDA and TensorFlow. Been a royal pain in the ass to get the Nvidia GPU’s free from X11 for pure compute mode. It is possible, and I even got it working on one mining rig. To the point, the login loop that happens with Nvidia drivers and the xorg system is caused by the open GL drivers and the integrated Intel GPU on the mobo. You can install the Nvidia drivers without open GL support and the problem goes away (you also need to blacklist the Noveau drivers when you do this, use: “sudo NVIDIA-Linux-x86_64-38x.xx.run --no-opengl-files”). Mind you that once open GL is installed, you cant un-install, and have to start over with a fresh install of Ubuntu. If you force the EDID.bin X11 option you can get the Integrated graphics card to run video and keep the Nvidia cards in a compute only mode. Gets you an additional 50-60 Sol on GPU0 and eliminates the login loop issues that happen occasionally. Its working great for TensorFlow but I still see some bugs with the miner… I’m not spending much time mining on this rig as its now an AI Neural net workstation, but once I have the time, I want to convert to a mining image I can use on the rigs and I will update.
Hope this helps.
