Message 94263 - Posted: 14 Dec 2019, 19:00:29 UTC

Hi,

I've installed the nvidia proprietary installed, installed boinc, add projects. steam games are working, proof that the videos drivers are working. So is there a symbolic link that I should do somewhere because boinc doesn't find the right libraries?
OS: fedora 31 workstation

Thanks in advance for all the leads you could provide.

Post the output of
lspci | grep VGA

Did you install the OpenCL drivers for your GPU?

sorry for the delay.
$ lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GM204 [GeForce GTX 970] (rev a1)


And I've isntalled the nvidia proprietary drivers and cuda from nvidia so I guess it should be packaged into that no?
How would I verify that accurately?

Did you reboot after installing the drivers?

Usually BOINC will tell you what if found in its log, the first 20 lines or so should show what it found. Please post those log lines.

From memory all it does is look for the OpenCL.so and CUDA libraries in particular folders. Given the 440 drivers are new it’s possible Nvidia put then in a new location.

sorry but where would be that log?
Because I don't have anything really consistent with that in /var/lib/boinc
or do you want me to copy paste the event log of boinc manager?

there is nothing really important in the std* txt file and there is no where I can see i nthe documentation the location fo the log for boinc and nothing in /var/log/
Or do you want me to activate some logs flags in the manager?
Best regards

So according to that there aren’t any usable GPUs which suggests you don’t have the right driver installed. It also says you’ve installed the pocl OpenCL which there are reports of it not being suitable for projects to use. I’d suggest getting rid of it.

I use Debian and have to install the nvidia-kernel-dkms package along with nvidia-opencl-icd. Seeing as you’re using Fedora that won’t work for you. A quick google search came up with this: https://rpmfusion.org/Howto/NVIDIA#About_this_Howto which has a section on CUDA. I’m not sure how up to date it is and there is no mention of the RTX2000 or the GTX1600 series of cards (ie current models). You’ll need CUDA and OpenCL to use them on most BOINC projects. There is mention of them being a third party ppa on the Fedora site.

Message 94385 - Posted: 19 Dec 2019, 8:39:35 UTC - in response to Message 94384.  

I'm installing my drivers manually from the official website. No repo and I'm not really interested to let the control to those repo.
The drivers are well installed as proven before with the different output I've put and because graphical program based on the nvidia drivers wouldn't work otherwise.

But about opencl I don't know since I'm not sure what would be the whole way to install it under fedora. As I've seen there: https://devtalk.nvidia.com/default/topic/1043943/linux/opencl-doesn-t-work-with-nvidia-driver-410-xx-415-13-drivers-for-linux/ The opencl extension are implemented into the nvidia proprietary drivers and the cuda drivers which as stated above I already installed. I can try to reinstall the cuda drivers from the website, not the repo as I did last time for example.

I don't know which version of opencl are available nor how to install it precisely since as shown in the link they are supposed to be in the drivers from nvidia. And the dkms package are already installed and at each update fo the kernel it rebuilds the nvidia driver proprietary as it should do. So the build and use of nvidia drivers here are not in question. They are working perfectly as intended. The problem is where does the boinc-client looking for the librairies?

[root@fedo-mansion-ada ~]# sudo dnf history list all | grep opencl
[root@fedo-mansion-ada ~]# 


I can't get rid of something that is not installed by the system...
[root@fedo-mansion-ada ~]# lsmod | grep opencl
[root@fedo-mansion-ada ~]# 


So I don't know how it detected that something related to opencl is installed.

The only thing I cand find is that:
[root@fedo-mansion-ada ~]# sudo dnf list installed | grep opencl
opencl-filesystem.noarch                           1.0-10.fc31                         @fedora

well Apparently you were right. There seem to be no support anymore to manually install and activate the cuda requirements without installing the drivers and everything must be through the rpmFusion repo. It bothers me a lot but I will try and gives you feedback when it's done.

Because you have a GTX970 you could use an older driver from Nvidia, not the 440. I found this site that has instructions about installing the official Nvidia drivers which might help.

thanks for the link I will look into it.

I've tried the rpmfusion way. Now I have artifacts at boot, steam games that I sued to test the graphic acceleration won't work anymore. I have a less fluid interface now, still harware accelerated but I can detect some differences.
And I'm pretty sure the driver were well installed before because in the uninstaller I've seen some line about libcuda.
And now boinc, which I modify the flag log, is complaining about libcuda. So I'm pretty sure that the system was okey but boinc wasn't detected libcuda before as for now.

So again, where boinc is looking for? Because clearly it's the problem. And it's the presence of libcuda that tells boinc if there is a GPU usable or not, nothing else.

/usr/lib/libcuda.so
/usr/lib/libcuda.so.1
/usr/lib/libcuda.so.440.44
/usr/lib64/libcuda.so
/usr/local/cuda-10.2/doc/man/man7/libcuda.so.7
/usr/local/cuda-10.2/targets/x86_64-linux/lib/stubs/libcuda.so
/usr/share/man/man7/libcuda.so.7


that's where it is installed on my fedora workstation.

Now that I thought about it, using an older driver is not possible when dealing with graphics.
As stated in several steam github issues, the xorg version has to match the driver version so that the usernamespace can access graphic acceleration capabilities.

https://github.com/BOINC/boinc/blob/master/client/gpu_nvidia.cpp teaches us that BOINC checks for libnvidia-ml.so.1 and libcuda.so using the dlopen function which will check /lib and /usr/lib automatically.

libcuda.so only checks for which CUDA version you have, it doesn't check which Nvidia GPU you have, which is a first requirement done by libnvidia-ml.so.1

Message 94395 - Posted: 19 Dec 2019, 11:03:50 UTC - in response to Message 94394.  

you are avoiding the question because the error message specifies that libcuda is not found and I just show you that it is there and that the symbolic link is functional.

But okey let's talk about the other lib then:

/usr/lib/libnvidia-ml.so.1

so it's totally not a problem of lib since they are there and that the hardware acceleration is working and the cuda application of nvidia are working as well.

So what should I do ? a ticket then?

Do you have either of

stderrgpudetect.txt
stdoutgpudetect.txt

in your boinc-client directory? Do they help?

Please add the following cc_config.xml file to your BOINC data directory /var/lib/boinc

<cc_config>
<log_flags>
<coproc_debug>1</coproc_debug>
</log_flags>
<options>
</options>
</cc_config>
If the file exists, add the line in the correct place, or change its 0 to 1.

After that exit & restart the BOINC client.
Then post the output of the event log again.
