Configuring GPU

[Mavpt]

Hi everyone,

I just got into folding@home and (mostly) managed to setup everything, with the exception of my GPU.

I'm currently running Linux Mint (Ubuntu) and a GTX1070 with Nvidia's nvidia-driver-435.

Any help would be appreciated.

Thanks in advance,
Mavpt

You need to install the proprietary drivers from NVidia. OpenCL is normally delivered with them. Once those APIs are running, FAH should detect your GPU and list it a couple dozen lines from the top of FAH's log, along with the active version of CUDA and OpenCL.

I do have the proprietary drivers from NVidia (nvidia-driver-435), however FAH does not seem to be picking it up. The FAH control doesn't recognize its existence while running FAHClient gives:

00:13:48: OpenCL: Not detected: Failed to open dynamic library 'libOpenCL.so':

You do not seem to have installed OpenCL. I am not a linux user so I hope this hint helps.

"you need to manually install the ocl-icd-libopencl1 package. So a quick sudo apt install ocl-icd-libopencl1 fixed it."

[Yujah]

I just installed the client on to an Ubuntu derivative, and this part:

00:13:48: OpenCL: Not detected: Failed to open dynamic library 'libOpenCL.so':
00:13:48: libOpenCL.so: cannot open shared object file: No such file or
00:13:48: directory

you solve with [c]sudo apt-get install ocl-icd-opencl-dev[/c] followed by a [c]sudo service FAHClient restart[/c] (may need/want to pause any currently running WUs before you do latter; not sure if needed).

Which would in my case not be to say that I have the GPU slot running by the way --- but that might be due the GPU on that system being a truly ancient AMD HD 5770. [c]clinfo[/c] says all's well and the GPU slot is detected and displayed but is seemingly not picking up GPU WUs, and in the log it is instead of the above quoted bit stated that "OpenCL: Not detected: clGetDeviceIDs() returned -1".

Other than that the GPU slot looks fine so I'm not sure if that's in fact an essential error display. Would be interesting to know if you get that same thing in the log and/or if your GPU queue does indeed work after installing ocl-icd-opencl-dev. You would on Nvidia certainly stand a bigger chance of things "just working" than here on this ancient AMD...

Note; the [c] stuff was supposed to introduce "inline code" display on the forum; am used to that working from another forum...

So I managed to get it working (I think), but the FAHControl still doesn't recognize it.

So I managed to get it working (I think) [ ... ]

So what did you do?

In any case, it might be the case that you need/want to setup the client from scratch with e.g. fahclient --configure or, better certainly if you already have a CPU WU running, manually add a GPU slot through FAHControl -> Configure -> Slots -> Add. I.e., just move the selection in that dialogue from CPU to GPU and click OK. Again may or may not have to restart after that.

[Mavpt]

So what did you do?

Followed your advice in:

you solve with [c]sudo apt-get install ocl-icd-opencl-dev[/c] followed by a [c]sudo service FAHClient restart[/c] (may need/want to pause any currently running WUs before you do latter; not sure if needed).

In any case, it might be the case that you need/want to setup the client from scratch with e.g. fahclient --configure or, better certainly if you already have a CPU WU running, manually add a GPU slot through FAHControl -> Configure -> Slots -> Add. I.e., just move the selection in that dialogue from CPU to GPU and click OK. Again may or may not have to restart after that.

Already tried to do so both ways, always getting the same result. It works (I believe) when I run sudo FAHClient from the terminal, but isn't recognized (even when I attempt to add it in FAHControl -> Configure -> Slots -> Add using the default (-1) configurations).

Even went as far as reinstalling the whole thing but without any success.

[Yujah]

Ah. Well, that's a little unfortunate, as I believed would be able to assist there, having done much the same earlier this evening. As to the reinstall, did you "sudo apt-get purge fahclient" to also remove current configuration rather than just "sudo apt-get remove fahclient" or similar?

And, yes, I do suppose you'd first need to stop the current FAHClient ("sudo service FAHClient stop") and then configure as root, "sudo FAHClient --configure", before starting it again; "sudo service FAHClient start". But.... certainly if you purge rather than just remove a reinstall should do the same thing, so if that's not working, seems I'll unfortunately not be able to assist after all.

[Mavpt]

"sudo apt-get purge fahclient"

Did that for fahcontrol and it did the trick.
Thank you very much for your help. I'm still very much new to Linux and still getting used to all the... details lets say

[Yujah]

I'm very new to FAHClient, and not so much to Linux

Very good to know that it now works. If you can, please let me/us know if the GPU slot now also in fact picks up WUs; if it does, I'll take that "clGetDeviceIDs() returned -1" thing that I myself had more seriously...

[Mavpt]

Both the CPU and the GPU are showing progress on FAHControl if that's what you're asking.

[Yujah]

It is. Darn; that means I get to debug OpenCL on an ancient AMD chip on Linux. Thanks

You're welcome. Good luck!

For the next poor sod that hits on this thread trying to get his AMD HD 5770 or more generally HD 5000 series card folding: after (on Debian/Ubuntu/Mint/...)

- installing ocl-icd-libopencl1, ocl-icd-opencl-dev and mesa-opencl-icd
- creating a file /etc/default/fahclient consisting of "USER=root" so as to run FAHClient as root
- although I don't think it's necessary other than for auto-configuration downloading http://fah-web.stanford.edu/file-releas ... c/GPUs.txt to /var/lib/fahclient/
- if not auto-configuring manually adding a GPU slot through FAHControl -> Configure -> Slots
- restarting with "sudo service FAHClient restart"

... FAHClient itself feels everything hunky dory. The log says e.g.

******************************* System ********************************
[ ... ]
GPUs: 1
GPU 0: Bus:3 Slot:0 Func:0 AMD:4 Juniper [Radeon HD 5700 Series]
[ ... ]
OpenCL Device 0: Platform:0 Device:0 Bus:NA Slot:NA Compute:1.1 Driver:19.2
***********************************************************************

and the GPU slot appears fully functional. Upon requesting a WU it is however assigned 192.0.2.1 as its work server; an unroutable and for documentation and examples reserved IP address. It seems that the assignment server therethrough basically says "unsupported GPU" --- although I note that the above displayed GPU string "Juniper [Radeon HD 5700 Series]" does in fact appear in the at the time of writing current GPUs.txt.

What appears to be the eventual issue is that the HD 5770 does not support OpenCL double-precision; that with that generation of AMD GPUs only the top models in the 5000 and 6000 series do, the 5800 and (supposedly) 5900 series and 6900 series if I'm not mistaken, and that current GPU WUs (almost?) universally do require double-precision.

EDIT: Very specifically, I believe it's HD 5830+ (TeraScale 2), HD 6930+ (TeraScale 3)

As in, no dice; isn't going to work on anything lower than 5800 series certainly.
