Hello friends I'm trying to build a headless Ubuntu rig to crunch data using the boinc-client. CPU crunching works like a charm, but the GPU is another matter! As soon as you are trying to make it "headless" the problems appears. Me and several others have been trying for more than 1 1/2 month to get it to work. There's several way some has got it to work, they say. Some trough OpenCL/CUDA, some trough "Wine" and some just give up and does it using GUI. I tried to make a Ubuntu Server box with the minimum required X packages. I tried to make a Ubuntu Desktop box and then remove the GUI to keep it as headless as possible. Using the standard Ubuntu Desktop Edition will mean that it works, but it's slow. There's a significant difference between the result of a box running the Desktop Edition and a box running e.g. the Server Edition, even though the GPU doesn't run on the Server Edition. This is the problem! I found a guy in the Netherlands who solved the problem. But ever since the Ubuntu update to 12.04.4, it doesn't work any more. The Nvidia CUDA driver .deb file doesn't work with 12.04.4. I tried several different distro, always the same issues! If anyone have a working headless GPU crunching rig I would very much like to know about it. We have been discussing this in several forums. Berkely.edu, overclock.net, ubuntu community, ubuntuforums.org, Nvidia developer forum, hardwarecanucks.com, xtremesystems.com and a couple more. I've been fighting this issue for a long time. If those of you who really knows about Linux, GPU processing and CLI environments would please come to our aid, I would be so much happier than I am right now. I don't mind reading, I don't mind trying and I don't mind asking and trying all sorts of suggestions. But I do mind to give up! This has been my worst problem ever! I've never had a problem where everything works against you. And when you suddenly finds a solution, then a update destroys that as well... If anyone is interested in the discussion we did, all the materials and the work we have done so far, please don't hesitate to let me know. I will make a list of all treads and posts in forums, links to all the related sites and copies of all the ToDo's I did up until this moment Ubuntu 12.04 is the one I know best. .
