Folding Forum

Posted: **Sun Nov 22, 2020 6:57 pm**

Felt proud of myself for getting OpenCL working (symlink /opt/amdgpu-pro/lib64/libOpenCL.so to /opt/amdgpu-pro/lib64/libOpenCL.so.1)
Then spent a few days thinking that the fact I was seeing no activity from my GPU was due to the advertised lack of WUs (even though running folding on Windows found WUs easily)
Then tried deleting and adding back the GPU slot a couple of times. Checked that it is running FahCore_22. Watched the logfile for clues.
Then yesterday I saw a logfile that indicated that the GPU had successfully downloaded a WU. But still it sits idle.
I have folding power set to Full
I'm stumped.
Here's the logfile : as usual it doesn't even seem to have requested a WU for the GPU. The last thing for the GPU slot is, as always "18:50:51:WU01:FS01:0x22: Configuring platform OpenCL"
and there it sits.
Thanks for any sugestions.

Code: Select all

Would you mind telling me what distribution you are using (Fedora; CentOS; Debian; Ubuntu; other)? Please include version information where possible.

I am looking at your information, and am trying to see if there is a specific set of updated AMD drivers for your distribution, so we can start narrowing down possible solutions (between me, and the other more experienced folders with more technical knowledge).

From what I see, the OpenCL libraries are not loading [correctly]. Do not pay attention to the warning about the CUDA libraries not being detected--AMD cards/iGPU's don't support CUDA (that's an NVidia technology). Where did you obtain the OpenCL library files?

Addendum:

Please see https://www.amd.com/en/support/kb/relea ... inux-20-45 for the most recent drivers (11/18/2020).

Thanks! I'm using OpenSuse Tumbleweed fully updated
I though I had won when I stopped seeing "OpenCL not found" errors in the log - obviously not!
I'm using amdgpu-pro-20.40 and the latest is 20.45 so I'll update that and let you know.

Try getting that OpenCL library package from here: https://software.opensuse.org/package/ocl-icd

in the past loading the opencl dev drivers has helped - https://foldingforum.org/viewtopic.php? ... ev#p345235

If you know the command for installing them from OpenSUSE's command line, that might help. As I think the one shown in the post you link to is for Debian.

I posted link simply to save time as to the driver name (originally just typed dev drivers) ... with linux I have to leave it up to folders to work out their own way of finding installing such for their distro as there are too many damn options for a poor windows guy like me to keep track of

I know.... What works in Fedora, may not in OpenSuse.

There comes a point where Duck Duck Go (the search engine) becomes one of your best tools.

yup ... or google/bing/etc. ... the important bit was to get (however one does) the ocl-icd-opencl-dev drivers and install them (by whatever method one does with fedora) ... I have no clue if the following is the right stuff for the linux version in use but it was what I quickly found with google ... https://pkgs.org/download/ocl-icd-devel-64bit ... hope this helps the op - might not be the solution anyways - but the presence of those dev drivers have solved many Opencl issues for others

What can further complicate matters is that the most recent build of Core_22 for GPU folding is distributed with the necessary OpenCL runtime code. That can sometimes conflict with the dev kit code if the versions don't match and the dev kit is installed. They are looking into the problem and a future revision of the core may include a fix.

In theory the dev kit should not be needed at all. But with the proliferation of distros of linux, various levels of updates, and so on means that sometimes installing the kit fixes up something, and other times does not work.

On this thread, I have tried.... But as we can agree to, we (as folder's) are the ones who need to be knowledgeable enough to ask the right questions, from the right sources, in order to get the right answers.

Paul ... your efforts and thoughts are very much appreciated - I recall a good few "catches" from yourself that have helped folders ... my "knowledge" of linux is laughable tbh - I just have far too much free time and read pretty much every post made to the forums ... if I spot patterns I mention them - they may not be the correct solution but sometimes if I am lucky they help people get to solutions ... and hopefully I dont send people off in the wrong direction too often !! ... I hope none of my posts came across in any way as dismissive or anything else negative as they really weren't intended to - I am maybe a big tired and didn't post quite as thoughtfully as I might have ... Sorry ... Neil
