Problems with Folding@Home with AMD GPU on Linux

[Quoda27]

Hi All, I hope someone can offer some advice. I've got an AMD R9 270X in a Linux machine and I don't seem to be able to get it to fold. I think the relevant part of the log file is:

17:21:51:WU01:FS01:0x22:ERROR:exception: There is no registered Platform called "OpenCL"
17:21:51:WU01:FS01:0x22:Saving result file ../logfile_01.txt

I've installed the latest AMDGPU-PRO drivers, and as far as I can see there are packages installed with OpenCL in the title so... I'm at a loss.

Any adivce or help would be muchly appreciated.

Do you have FAHControl installed? Have a look at it's System Info, does it show a GPU and OpenCL Device?

 

I had to install the "opencl-amd" on Arch, the "opencl-mesa" package didn't seem to do it (got both installed now).

I do not. The FAHControl package won't install on my system(s) so I've got quite accustomed to using the command line and reading log files. (I do that for a living anyway) The log files recognise my GPU but mention nothing about OpenCL.

Anyway, I will try installing the two packages you mentioned and get back to you, thanks for giving me a thread to tug at.

I agree with @Eigenvektor, I had to install opencl-amd to get it to work on an ubuntu machine a while back.

Thanks! May I ask how you went about installing it? My repositories don't seem to have it, running 19.10.

There may be a way to see the system info from the command line, haven't tried yet. I have FAHControl installed on a single machine and use that to monitor both of my systems. You can also use "clinfo" from the command line to get information about whether OpenCL is installed and working.

 

This is what it looks like on mine, you should probably get a similar output:

From my experience on Ubuntu 18.04.3/19.04:

./amdgpu-pro-install --opencl=legacy,pal

You have to add the argument to install OpenCL support. I know this works for BOINC I have yet to test it for Folding.

It was in here, although the drivers and hardware have changed.  Mine was a Vega Frontier.

Thanks. clinfo returns:

Number of platforms                               0

So I clearly am missing packages. I'll keep looing for new things to install.

You can try "opencl-mesa", if that's available on Ubuntu. That did show up as a platform on mine, but I didn't seem to get WUs for it (but... that may just be an issue with general server overload). I did get some after I also installed "opencl-amd", now it shows up as 2 platforms...

 

I don't know how to get it on Ubuntu, unfortunately. It's not available in the official Arch repos either, it's part of AUR. So I suspect you'd have to either manually build it on Ubuntu or get it from some PPA.

Quoting this because its the solution. You have to install OpenCL with the driver package as an argument (at least on Ubuntu).
