Linux / CentOS 8 / AMD Radeon R9 / Beta Client

It seems that a lot of GPU problems revolve around specific versions of drivers. Though AMD has their own support structure, you can often learn from information reported by others who fold.

Linux / CentOS 8 / AMD Radeon R9 / Beta Client

Postby Amarand » Sat Apr 25, 2020 3:54 pm

New to the group and Folding@home in general, and while I have a PC running Windows 10 chugging along on a CPU and GPU, and my MacBook Pro is likewise running on a CPU and GPU, my Linux machine is CPU only for now.

I spent the morning working with various troubleshooting guides on-line, and I've got it to the point where, running the latest FAH beta 7.6.12, I can get the GPU into "Ready" state, which is nice, but the logs are throwing:

Code: Select all
14:43:06:WARNING:WU00:FS01:Failed to get assignment from 'assign1.foldingathome.org:80': No WUs available for this configuration


and

So it doesn't look like WU00:FS01 (the GPU) is able to work properly right now?

Welcome to the F@H Forum Amarand,

Please note that it seems your GPU isn't being detected by the client:
14:11:14: GPUs: 0
14:11:14: CUDA: Not detected: cuInit() returned 100
14:11:14: OpenCL: Not detected: clGetPlatformIDs() returned -1001

Since you have an AMD GPU, you can ignore the CUDA message but the OpenCL and GPUs value are important. You will need to install AMD Drivers (proprietary ones, not open source) and also OpenCL package... at least from what I have read about Linux since I don't have hands-on experience with it.

BTW, you mentioned that your MacBook Pro is folding on the GPU. AFAIK, macOS doesn't support GPU folding so are you using Linux/Windows to fold on your GPU?

Oops! Yes, the MacBook Pro is CPU-only, sorry about that.

Yes, the PC is happily running with CPU and GPU.

Linux isn't quite there yet.

So you have to use the proprietary AMD drivers, not the open source ones? That's unfortunate. I don't think my CentOS 8 will take the RPMs but maybe I can try building them from scratch? I'm assuming that GPU will be useful for folding, right?

One thing I noticed, there is an R7 iGPU shown as part of the APU installed in this system. I am assuming the R9 is a separate card. You may run into some issues if that R7 is enabled, but the client usually gets the OpenCL settings correct for the GPU slot when installed after the drivers and OpenCL support are in place.

You did not mention which specific Radeon R9 that you have, but even the oldest, slowest one should be able to fold well enough to meet deadlines. For the drivers, check that the version you have still includes OpenCL support for your card. AMD removed that support for some of their older cards in more recent versions. Some people have had to go back to the last or next to last Catalyst driver version.

It's the XFX repackage of the OEM Radeon R9 280. The problem is, my version of operating system (CentOS 8) is the latest...and the proprietary drivers for the R9 280 apparently don't install on Red Hat 8/CentOS 8.

When you said there's an R7, is that probably my integrated on-board GPU? I'm surprised that's not disabled.... Where does that show up?

And the R9, yes, is a physically separate dual-height PCIe card.

It is not currently showing up except as part of the CPU description:
Code: Select all
14:11:14:        CPU: AMD A10-7850K Radeon R7, 12 Compute Cores 4C+8G

Not necessarily a problem, just mentioned that in case you do run into a problem as a troubleshooting tip.

From what I have read, sometimes an older driver can be installed depending on the Linux distribution. Never did that myself. Looking at the AMD support site, they list RHEL7 as the highest version for the Crimson and Catalyst drivers.

Yeah...and I'm not sure they're ever going to upgrade to RHEL8/CentOS8, simply because they're older cards. So...I'll just use the CPU for now, and if someone out there with the same experience I'm having, was able to get things to work, hopefully they'll post here.

AMD has been pushing folks to upgrade to newer drivers which deprecate OpenCL. Try some older drivers.
