Linux - ID's GPU but won't fold

Rick_Dom · Post by **Rick_Dom** » Fri Jun 19, 2020 1:29 pm

Hello forum,

Sorry for what I hope is a simple issue: I set up an old machine on Linux Mint 18.2 and added a bargain nVidia GT 710 I found at a local shop. Setting up nVidia drivers in Mint was a real pain, but I got the system to work after some reinstalls. Now, F@H is up and running.

The issue is that F@H recognizes the GPU in the "System Info" but will not otherwise acknowlege it. The GPU isn't given a "slot," and the Log file below states "<gpu v='false'/>"

The CPU seems to be cranking away - does anyone know how I can get the GPU to work too? Thanks!!

Could you post the first 100-200 lines of your log file? That shows the hardware and client configuration as detected on installation and startup. If copying from the log window of FAHControl you may need to click on Refresh to reload log from beginning, and unchecking Follow will make it easier to scroll to the beginning.

Open advanced control (FAHcontrol). Navigate to Configure and tab Expert. Go to Extra cliend options and remove line GPU = false. Then go to tab Slots, choose add and be sure you choose small almost invisible radio button from the left side from GPU part. Ok, Save. Leave everything else as default in this phase. Reboot the Client and see what happens. I think you still need to install OpenCL but you'll see.

One remark: I think GT710 could be way too slow to fold. Unless it is capable to perform WUs within timeout it is quite useless.

Thanks TPL for the reply too - regarding your input,

One remark: I think GT710 could be way too slow to fold. Unless it is capable to perform WUs within timeout it is quite useless.

I hear you. This is the first GPU I've set up to fold. I'm asking to understand how to resolve the problem generally. I'll follow your advice after Joe_H's response.

Okay, the client is detecting the GPU hardware but not the nVidia driver or OpenCL support. If you have the mesa driver installed you will need to install the nVidia propietary driver and OpenCL support. In addition people have reported needing to install the OpenCL dev kit as well.

Several people have written up and posted here on how they installed on Mint. There has also been some recommendations for the write-ups posted on the Linus Tech Tips site - https://linustechtips.com/main/topic/10 ... lding-rig/.

As for the GT 710, on the positive side it is based on nVidia;'s Kepler chips. There may also be some work coming out soon that will be suitable for low powered GPUs from the COVID Moonshot projects F@h is working on.

You didn't get a bargan. As has been said above, the GT710 is one of the slowest GPU that FAH supports.

Does your case require the Low Profile device? I"ve got some Low Profile cases and I recommend you upgrade your GPU to one of the GTX xxxx LP devices. I've been happy with xxxx = 1050 or xxxx = 1050 Ti or xxxx = 1650, depending on how much you want to spend.

You'll still need the proprietary drivers.

Thank you all for the replies! The GPU now folds!

Joe_H: I followed the steps in the linked instructions for installing OpenCL and I believe this was crucial to my success. Prior to following the simple steps in the link, F@H wasn't recognizing OpenCL on my machine. Thanks for sharing the link!

TPL: I followed your instructions once I had made sure OpenCL was installed, and it worked! The GPU is now up and running! Cheers!

bruce: Indeed, the 710 cuts it close to fold by timeout, although it will certainly beat expiration. The case doesn't require an LP card - the GPU was just a target of opportunity - and I'll follow your advice to replace it soon. Still, I have a spare SFF machine that could use the LP card. If a machine can fold, I intend to make it do so.

Getting the 710 folding was tricky for me (mostly for Linux/nVidia driver troubles before F@H was even installed). I hope this can help the next person who wants to set up an old machine.

1. I installed Linux Mint 19.2 XFCE in compatibility mode. I checked "install proprietary drivers" during the setup process.
2. I booted the machine and ran the updater once, checking to make sure no Kernel updates. I then rebooted the machine.
3. I selected the latest nVidia driver from the list in the OS's Driver Manager. I then rebooted, as advised by the Driver Manager. I checked to see the driver was in use by launching the "NVidia X Server Settings" application in the System tab of the start menu.
4. I made sure OpenCL was installed as described in the Linus Tech Tips link from Joe_H, with the commands listed below in Terminal, checking the install with "clinfo" on the second line, and then reset:
Code: Select all
```
sudo apt install clinfo
clinfo
sudo apt install ocl-icd-opencl-dev
sudo shutdown -r now
```
5. I installed F@H using the links on foldingathome.org, set it to "medium."
6. I followed TPL's steps: Open advanced control (that is, FAHControl). Navigate to Configure and the Expert tab. Go to "Extra client options" and remove the line "GPU = false." Then go to the Slots tab, choose "add" and be sure you click the small, almost invisible radio button on the left side of the GPU part. With that button selected, click Save. Restart the client.

The steps above got my GPU folding! If someone else is having trouble - make sure the GPU is on the whitelist too

The visibility of that radio button depends on which theme is used. I often forget to mention that as I am used to the appearance of the one them available on OS X, there is is quite visible. But from the screen captures that people have posted of the various darker themes, it does get less obvious.
