I have two video cards installed . I installed the driver directly from the Nvidia site; both cards take the same driver.

The first card is a GeForce GTX 1650 the second GeForce GT 710B.

The first shows up in the Boinc users computers, the second does not show up at all.

Boinc is downloading CUDA WU’s but they are not being processed, Boinc-Manager shows the GPU as missing.

This started a couple of days ago upon trying to upgrade the drivers using the Debian repository as Nvidia-detect said the cards work under that standard install. Since that failed I uninstalled and went back to the drivers directly from Nvidia via [sh NVIDIA-Linux-x86_64-440.44.run].

The last part repeats 6 times so I did not paste here.


I must have missed some install step.

Suggestions please.

First 30 lines of the start up log from Bonic manager.

Did you install a cc_config.xml to use all gpus? Otherwise only the most capable GPU will be used.

---

you need to add a flag to your CC config to allow BOINC to use all GPUs when you have mismatched GPUs.

cc_config.xml and place in the BOINC main directory:

<cc_config>
    <options>
        <use_all_gpus>1</use_all_gpus>
    </options>
</cc_config>

next, about the errors, I believe the cuda60 app doesnt work well. just wait it out and the servers will send you SoG and sah apps again which seem to process properly on your system as of a few days ago.

First 30 lines of the start up log from Bonic manager.

Did you install a cc_config.xml to use all gpus? Otherwise only the most capable GPU will be used.

What is the name of the start up log? Client state? I didn’t see a file named start up in the Boinc-client directory.

its in the GUI. just hit ctrl+shift+E with the boincmgr GUI running. that brings up the log, you can copy and paste the first few lines from there.

There's no drivers being listed for that rig so I'd look further into that. ;-)

Cheers.

Cheers.

I saw drivers being used in the output from the first post. That does not mean they are installed?

The same question when it is showing in computers on the boinc site?

In the first post I described running the installer from nvidia; I didn’t get any errors. Is there another step I missed?

That rig only shows, "NVIDIA GeForce GTX 1650 (3911MB)", were it should be showing something more like this, "NVIDIA GeForce GTX 1650 (3911MB) driver: 440.44 OpenCL: 1.2", for it to work. ;-)

Cheers.

Thanks for that info. At least I know what to look for.

next, about the errors, I believe the cuda60 app doesnt work well. just wait it out and the servers will send you SoG and sah apps again which seem to process properly on your system as of a few days ago.

Or speed things up with this is cc_config.xml
<no_cuda>1</no_cuda>
That will prevent the CUDA60 from being used and force the SAH and SoG OpenCL apps on the host. Still need to see OpenCL being detected on BOINC startup for even that to work.

My system does not process CUDA?

Or speed things up with this is cc_config.xml
<no_cuda>1</no_cuda>

I'm worried about that line. It doesn't appear as an option in the User Manual, and it isn't written out in the full template when you change a logging option.

Also, it should be written in the config report at startup - and it isn't there in the log Radjin has just posted.

I wonder how he got and processed SoG and sah tasks already tho.

It was working until I did the update and added the second GPU. Now no matter what I do it does not load. I tried the standard Debian Nvidia-Driver install and that locks the system to where I have to do a hard restart then use recovery to remove it. Then I tried an install using Nvidia-driver install, as described here: https://linuxusers.net/debian/how_install_debian_10_buster_with_nvidia.php on step 5 using back ports. That ran but was not seeing the drivers. Lastly I went back to the drivers directly from Nvidia as described above and that’s where I am now. I have tried each step above with and without the second card installed.

You are going to need to figure out how to get the Nvidia OpenCL drivers installed somehow. I don't know what Debian has as an equivalent to the standard Ubuntu distro command:

sudo apt-get install ocl-icd-libopencl1

I thought that Jord proved that <no_cuda>1</no_cuda> works over at Github. I see it referenced several times in conversation.
