Open CL card not found, but card found easily. Linux

Post by markfw »

So I install Linux Mint 19, and then I followed the same procedure that I have done on my other 10 folding boxes. Below is that section
----------------------------------
wget http://launchpadlibrarian.net/109052632 ... 15_all.deb

sudo dpkg -i python-support_1.0.15_all.deb

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt-get update

sudo apt-get dist-upgrade

sudo apt-get install nvidia-390 (or if it appears on the linix home page drivers list, you can do it from there.

sudo apt-get install nvidia-opencl-icd-390

sudo apt-get install libcuda1-390

sudo apt-get -y install python-gnome2 mesa-common-dev freeglut3-dev nvidia-settings gedit
--------------------------------------------------
Then install the FAH client and fahcontrol
--------------------------------------------------
cd /var/lib/fahclient

sudo wget http://fah-web.stanford.edu/file-releas ... c/GPUs.txt
--------------------------------------------------
Then fire up fahcontrol and add the GPU client(will show under education in the menu), and maybe also the remote access by adding ,192.168.1.1-192.168.1.255 to the two IP places
--------------------------------------------------
sudo service FAHClient stop
sudo service FAHClient start

But then this happens:

02:04:10:ERROR:WU00:FS00:Failed to start core: OpenCL device matching slot 0 not found, try setting 'opencl-index' manually

Help !!!

I always install the following:

Code: Select all

sudo apt install ocl-icd-opencl-dev
If that doesn't help then, using FAHControl, go into the configure > slots > gpu and change the opencl-index from -1 to 1.

Do you have an on-board GPU that hasn't been disabled? If so, the above should help.

What does your log show for the following:

Code: Select all

23:57:02:           GPUs: 1
23:57:02:          GPU 0: Bus:2 Slot:0 Func:0 NVIDIA:7 GM200 [GeForce GTX 980 Ti] 5632
23:57:02:  CUDA Device 0: Platform:0 Device:0 Bus:2 Slot:0 Compute:5.2 Driver:9.1
23:57:02:OpenCL Device 0: Platform:0 Device:0 Bus:2 Slot:0 Compute:1.2 Driver:390.48

Nope, the CPU is an AMD 2990WX, no onboard GPU, I will try the other

You may have another opencl device ... try changing the index anyway.

Please provide the log section as shown in my edited post above.

Also, did you restart the client after changing the index?

Doing :

sudo apt install ocl-icd-opencl-dev

And stop and restart the client worked, thanks,.

It would be interesting to figure out what is actually going on so the client can avoid this error for others -- or at least tell the Donor what to fix.

Please find the recent logs in the logs subdirectory in FAH's working directory and show what changed in the section displayed by bollix47 above when you installed ocl-icd-opencl-dev.

Here's how I install F@H 7.5.1 on a new Linux 19 Mint computer. Upgrading from Linux 18 to 19 too littered with bugs and problems. Do a fresh Linux 19 install.
It's easier than it used to be:
1. Install Linux 19 iso (v2 or later, v1 has bugs). Reboot.
(If Linux 19 already installed then remove any older drivers. sudo apt-get purge nvidia-*)
2. First thing open Driver Manager and install latest (396.54) Nvidia driver.
3. sudo apt install ocl-icd-opencl-dev
4. sudo reboot
5. Open Synaptic Package Manager & select Consider recommended packages as dependencies.
6. Let Update Manager install all updates.
7. Go to https://foldingathome.org/start-folding/ & Save fahclient_7.5.1_amd64.deb & fahcontrol_7.5.1-1_all.deb.
8. Doubleclick fahclient_7.5.1_amd64.deb
9. Doubleclick fahcontrol_7.5.1-1_all.deb
10. Open FAHControl & configure. Slots/delete CPU or if you leave it F@H won't automatically install GPUs. Expert/delete anon & gpu false.
11. Sudo reboot. FAHClient automatically assigns all CPU & GPUs.

did you try setting the openCL field to "0" and not "1" or "-1" ?
