Fedora 31, Nvidia GT 1030: clGetDeviceIDs() returned -1

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

Fedora 31, Nvidia GT 1030: clGetDeviceIDs() returned -1

Postby Markus_Laker » Sat Mar 21, 2020 12:02 pm

I'm running 64-bit Fedora 31 on a machine with an Nvidia GeForce GT 1030. I've installed version 440.64 of the binary Nvidia drivers from rpmfusion. I've also (after reading around) installed the ocl-icd-devel package. I'm using a version of FAHControl that I've modified in one way: the shebang line explicitly requests Python 2, because the default on F31 is Python 3. I've made no other changes to FAH software. When I try to add a GPU slot, FAHControl says no GPU is available. Here's my current log:

How can I get FAH to use my GPU?

Thanks for any help you can give, and for all the amazing work done by the FAH volunteers.

Re: Fedora 31, Nvidia GT 1030: clGetDeviceIDs() returned -1

Postby goodyca » Sat Mar 21, 2020 3:48 pm

One thing to check is the existence of the GPUs.txt file. It should be in the /var/lib/fahclient directory. When I added the GPU on a Fedora 31 install, it was missing. The GPUs.txt file can be downloaded from:

Re: Fedora 31, Nvidia GT 1030: clGetDeviceIDs() returned -1

Postby Markus_Laker » Sat Mar 21, 2020 7:08 pm

It's already there, thanks, and it mentions my graphics card:

Code: Select all
[msl@localhost ~]$ grep 1030 /var/lib/fahclient/GPUs.txt
0x10de:0x1d01:2:5:GP108 [GeForce GT 1030]
0x10de:0x1d12:2:5:GP108 [GeForce MX150 (GT 1030) Max-Q]
[msl@localhost ~]$


What else should I try? Do need to do something about the errors reported by `clinfo -l', or are they not relevant to FAH?

Thanks again,

Markus

Re: Fedora 31, Nvidia GT 1030: clGetDeviceIDs() returned -1

Postby Joe_H » Sat Mar 21, 2020 8:42 pm

Does the Device ID for your 1030 match either of those two entries? Just asking in case they have come out with another variant than those. A new entry would be needed for a new ID if the one you have does not match.

You have installed:

nVidia driver - check
opencl dev kit - check
nvidia OpenCL - ? asking in case it was not part of the driver rpm

About the device ID -- I have this:

Code: Select all
[msl@localhost ~]$ lspci | grep -i vga
41:00.0 VGA compatible controller: NVIDIA Corporation GP108 [GeForce GT 1030] (rev a1)
[msl@localhost ~]$


I'm well outside my area of expertise. Is that string "GP108 [GeForce GT 1030]" the device ID you have in mind? If so, it looks like a match.

About Nvidia OpenCL: I don't know, but this --

Code: Select all
[msl@localhost ~]$ find /usr/lib64 -iname \*opencl\* | regrep -viX '/ (?: libreoffice | clang ) /'
/usr/lib64/libMesaOpenCL.so
/usr/lib64/libOpenCL.so
/usr/lib64/libnvidia-opencl.so.1
/usr/lib64/libOpenCL.so.1
/usr/lib64/libnvidia-opencl.so.440.64
/usr/lib64/libMesaOpenCL.so.1.0.0
/usr/lib64/libOpenCL.so.1.0.0
/usr/lib64/pkgconfig/OpenCL.pc
/usr/lib64/libMesaOpenCL.so.1
[msl@localhost ~]$


-- looks to me as if the answer might be yes.

libOpenCL.so is a symlink to libOpenCL.so.1.0.0 in the usual way.

Thanks again,

Markus

Could you run fahclient --lspci from a command line? That lists the various PCI devices including the GPU and gives the device ID as well. You may need to cd /usr/bin first.

So perhaps the piece of code it was about to run forgets to check whether an earlier piece of setup code managed to read in the necessary data or not.

Thanks for persevering with this.

Re: Fedora 31, Nvidia GT 1030: clGetDeviceIDs() returned -1

Perhaps try with a single '-', FAHClient -lspci. There are so many different commands that sometimes use it singly and other time doubled, I sometimes forget which and have to try both.

Another possibility is the command ran into a protection issue, it may need to be run with sudo. From what out it did generate, it dd manage to scan part of the system and return values for AMD and Intel devices before segfaulting. Recent versions of Linux have been moving GPU/video resources into groups that can require privileges to access.

Hi, Joe. -lspci with a single dash produced an error message:

Code: Select all
16:52:23:ERROR:Exception: Invalid argument '-lspci'
16:52:23:ERROR:Caused by: Option '-lspci' does not exist.


`sudo FAHClient --lspci', with two dashes and a `sudo' produced the same output as it does without `sudo', and ended by segfaulting in the same place as before.

Cheers,

Markus

My hunch: You need the proprietary drivers from NVidia, not the ones commonly distributed with Linux. You'll probably find that they include an OpenCL package that works with their CUDA API but I have not updated my LInux servers in a long time.

Be especially careful if you install drivers while X is running. [i.e. don't unless you get a package that was tested on the GUI version of Linux.)

Hi, Bruce. You're right -- Nouveau, the open source driver that ships with Fedora, doesn't support OpenCL. I reluctantly installed Nvidia's proprietary drivers from RPM Fusion last year, because I found Noveau too unstable with dual monitors, and I'm currently running version 440.64. The clinfo transcript I posted here over the weekend and the presence of /usr/lib64/libnvidia-opencl.so.440.64 and /etc/OpenCL/vendors/nvidia.icd suggest that these drivers support OpenCL, or at least try to.

Nouveau is still installed, but disabled via kernel boot parameters. That's the way the driver from RPM Fusion sets itself up by deault. I don't want to uninstall Nouceau, because I know that Nvidia proprietary drivers can stop working when the kernel is upgraded, and Fedora upgrades its kernels quite aggressively.

Intel's Beignet software is also installed on this machine, which seems a little odd, since I have an AMD processor and Nvidia graphics card. I'm guessing that Fedora always installs Beignet on AMD64 systems.

It's not clear to me if OP installed nvidia-opencl-dev in addition to ocl-icd-opencl-dev. I'd double-check this before pursuing bruce's wise suggestion of installing drivers straight from NVidia.

Hi, katakaio,

When I google `nvidia-opencl-dev', I find a package for Debian-based distros, but I'm running Fedora. Fedora has no package of that name that I can find.

Thanks,

Markus

Thanks Markus - sorry for the bad tip! My Fedora knowledge is rusty, and I didn't realize that such a package didn't exist for Fedora (or if it does, I don't know the name). Installing ocl-icd-devel may be sufficient, but I install nvidia-opencl-dev on my Ubuntu rig (along with packaged NVidia drivers from a PPA) just to be safe.

At this point, I'd second bruce's suggestion of installing proprietary drivers from NVidia's .run files. They tend to bundle everything that you'd need (OpenCL, CUDA, etc), so let us know if you have more success with that.

Thanks, katakaio, but I've been burnt that way once before. I tried installing Nvidia's drivers by following the instructions on a site called If Not True Then False. The instructions had me uninstall Nouveau and then reboot, and then I found that the Nvidia drivers wouldn't build on my system, and so I ended up without an X server. I eventually had to rebuild it by booting up a live image and using a chroot to reinstall Nouveau. It's not the first time I've had Nvidia drivers that wouldn't build -- it happened to me several times on Debian in a past life.

I daren't do anything to destabilise this machine -- I need it all day, every day, to work from home during the Covid-19 outbreak. It sounds as if I won't be able to do GPU folding at present. But I thank you, along with Bruce, Joe_H and goodyca for your time and suggestions. CPU folding on a 12-core Threadripper is still a decent contribution to be able to make to the cause. :)
