Message 61565 - Posted: 21 Apr 2014, 6:32:55 UTC

http://milkyway.cs.rpi.edu/milkyway/hosts_user.php
I have a PC with AMD GPUs and the LinuxMint 14 64bit Cinnamon system.
I have my MilkyWay@Home preferences set to run on Use ATI GPU.
However, The above link shows that Milkway can not see my GPUs.
Does someone have an answer for this?

Thanks

Getting AMD drivers to work in Linux is a bear unless you are a Linux guru, which I am NOT! I personally gave up and only use Linux with Nvidia gpu's or on some machines with no gpu.

Thanks, Mikey. That is just what I needed to hear. :(

I know, I am sorry! Check all the gpu projects as somewhere I saw a posting of how to make it work, it was not for Mint though. A year or so ago I think I remember someone else saying they too had problems getting a gpu to work in Mint, I don't think they ever got it fixed and ended up changing to a different distro. LOTS could have hanged since then though, Linux does NOT stand still for long.

It's awake! I took your advice and swapped out the AMD for NVIDIA GPUs.
Then, used the command sudo service boinc-client restart
Now I'm up and running.

Thanks Mikey for the suggestion. I still think if Linux can crunch with NVs they should be able to do it with AMD.

But what do I know. I'm just a retired engineer and an active Wizard.

I am very glad it is crunching, but also wish you could have gotten the AMD gpu to work! Oh well now you have the opportunity to do it on a different machine, AND the start of a farm or even a ranch!! I think 5 pc's equals a garden.

The AMD GPUs run very well on Linux for Milkyway, the tahiti based in particular.

For the driver installation you have two options:
1. Installation of the distribution packages (debian based works good).
2. Or of the driver packages from the AMD side [1].

In any case, you have, as opposed to windows, also install the AMDAPP SDK [2]. Although it indeed explicitly for CPU, but without boinc does not recognize the GPU.

Furthermore, one must consider when AMD OpenCL, the need for a user to be logged in Xserver must and will be allowed on this access to the GPU.
Actually you just have to, every time you log in,
xhost + local
run and then boinc start/restart.
Also you can use
clinfo
to check whether the OpenCL GPU is detected below a user or root.

Well when you put it that way... One would think Boinc could come up with a way to make all that happen under the crunching account IF the user hasn't already done it for other reasons, ie gaming. The more people crunch the better Boinc is for everyone, making it install ALL the needed parts in the different version of Linux could be a pain, there are THOUSANDS of them, but one could think they could come up with several installations that just work well with Boinc right out of the box, including the gpu's.

Any clues as to how to get the nvidia cards working would be welcome: my client is also repoerting 'no usable gpus' on suse 12.3 with nvidia drivers installed and working.
I'm obviously missing something - but what?

Let me start off by saying I am NOT a Linux guy, but are you really running Linux Mint? If so that could be the problem, a while back other users reported that when running Mint there was no way to also run Boinc using a gpu, it just wasn't built for it. I know it works under Ubuntu, it is bigger and a bit different then Mint, I have tried almost a dozen flavors of Linux and just keep coming back to Windows as it's what I grew up with.

The core of Mint is Ubuntu, it just has a lot of graphical enhancements on top.

I did at one point have the GPU working on a Linux Mint installation, but that was just a test machine and it went back to being my TV machine.

I must agree - getting Linux to work with an AMD GPU should not require a degree .... if the folks at Milkyway don't care enough to set up a definitive webpage with explicit instructions for how to get this to work, then f*ck 'em - I'm not going to bring more effort and passion than they do - I'll go Fold@home - Bye!

Try installing the latest CUDA toolkit to get the CUDA/OpenCL environment setup.

(It should be available via the package manager).
Once installed shutdown and reboot, cross fingers, and hopefully it will go.

Cheers
