CUDA: Not detected. Linux Debian Stable

Thank you for the reply, Bruce, but yes, I did look further up in the log file. From my first post on this topic I showed the entire System block of the output (which has not changed no matter what I do):

Note the lack of any CUDA or OpenCL device info lines like you have after the listing of your GPU and what might, comparing mine to yours, be some debug output in my System block. And I do agree that FAH determines the hardware configuration just once at the start, which is why I'm befuddled that it successfully folds with OpenCL if there is nothing in the System block of output indicating that it was found. Specifically:

(The first "OpenCL" in what I just pasted above is the first time OpenCL appears anywhere in the log file.)

You asked if OpenCL was available when FAH started up. To ensure that it is, I put a 60 second delay at the start of /etc/init.d/FAHClient to hold FAH off until the rest of the system is fully initialized. (This is a fresh install, so other than FAH there are only the small number of default services that start up, so 60 seconds would give them plenty of time.) Doing this made no difference. I'm letting the current jobs finish and then will try starting FAH manually but with the added cuda-device and opencl-device parameters to see if that changes anything.

You still have not posted the complete first section of the log. Bruce has given you an example, post that section without removing stuff. The client configuration is in the next section, posting the first 100-200 lines usually catches everything pertinent.

The extra lines:
6:27:49: CUDA: 7.5
16:27:49:CUDA Driver: 11030
suggest that you're installed the CUDA toolkit. FAH expects the nVIdia drivers but NOT a toolkit which is probably incompatible with the one carried inside of FAHCore_22.

craig110 · Post by **craig110** » Thu Apr 29, 2021 2:05 pm

My last install I made sure the toolkit wasn't in any of the steps. To confirm that it isn't on the system, here is the nvcc --version output...

$ nvcc --version
Command 'nvcc' not found, but can be installed with:
sudo apt install nvidia-cuda-toolkit
$

...and doing a dpkg -l | grep toolkit shows 12 packages, none of which have anything to do with CUDA.

As per Joe_H's request, here is everything in the current log from the start of the program to where it is crusing along crunching. Note that this was immediately after a fresh install of the OS, thus you'll see the download of the client code as well. (The squawk about dumping slot 0 is due to it automatically starting with CPU-only folding and me switching that to using the two GPUs.)

Code: Select all

I doubt this will shed any useful light on the no-CUDA problem, but just in case (and being a software developer I know how often those "this probably doesn't matter" ends up being a key point

), but watching the Linux box via running FAHControl on my Windows box has the descriptions and the progress of my two cards reversed. I noticed this once while I was suspending the jobs and FAHControl showed that my 1660 Ti was done but the 1080 Ti was still working. However, psensor showed that the 1080 Ti's fan was at 0% and was idle while the 1660 Ti's fan was still running in the 60% range and was happily crunching numbers. This was, thankfully, an easy thing for me to check on since the 1660 Ti is on a riser card and is outside the case so whether its fan is running is easy to see. It was still running. Since the 1080 Ti is much faster than the 1660 Ti, I've noticed this happening consistently anytime I'm suspending the jobs and FAHControl says that the 1660 Ti is done and the 1080 Ti is still running. PPD between these two cards is also reversed, so it is as if FAHControl reversed the "[GeForce GTX...]" strings for the slots but got everything else right.

I think you need the display driver libcuda.so—the CUDA driver on Linux system. Without that driver, CUDA will not operate. I got it when I installed a package with the proprietary driver.

There's some kind of connection between the display driver version and the CUDA version which might be violated if you have a toolkit.
https://docs.nvidia.com/deploy/cuda-com ... index.html

craig110 · Post by **craig110** » Fri Apr 30, 2021 11:45 pm

Thanks, Bruce, but I've confirmed that the system (now running Mint to see if it behaves any differently) has libcuda.so and nvidia-smi shows CUDA Version 11.2. Is there anything that has to be in PATH or LD_LIBRARY_PATH when the toolkit is not present?

clinfo's NULL platform behavior block shows "No platform" for the result of clCraeteContextFromType(NULL, CL_DEVICE_TYPE_GPU) if this helps. (Harkening back to my wish that FAH had more CUDA-related debug output, I don't know if this is how FAH identifies CUDA devices or not.)

Thanks, and keep the suggestions coming.

Yoiu are also running a version of the client that is two major versions behind the current one. The current version is 7.6.21, your log shows version 7.4.4. Version 7.5.1 was the previous major release, that is about 4 years old.

Post by **bruce** » Sat May 01, 2021 6:46 pm

We recommend that everyone install OpenCL. For NVidia GPUs, CUDA is the preferred platform, but OpenCL is a backup platform if there are problems with CUDA.

Thank you, Joe_H - that was it. FAH is running via CUDA now.

I am downright stunned (as an understatement). I followed the installation directions *on the FAQ Linux installation page* and so have been wasting my time (and beating my head against a brick wall) with software that is ancient?!?!? Oh, F@H powers-that-be (or at least website maintainers), I'm just shaking my head with sad disappointment. Please, is it so hard to update the FAQ *installation* instructions to point to the current software version? Please please please please please, help us help you.

Unbelievable.

(From a top-2500 contributor.)

Post by **Joe_H** » Sun May 02, 2021 5:43 am

The installation instructions and some of the other FAQs used to be maintained by a volunteer who passed away a few years ago. This coincided with the move of F@h from Stanford. Just the basic work to get the website up and fix some broken links has been done for most of the time since. Only in the last 6-9 months has someone been picked to work on the F@h main site, so there is a backlog of updating to be done.

Not sure when the installation instructions will be updated, hopefully not too far in the future.

Post by **bruce** » Sun May 02, 2021 6:51 am

I don't know who can rightfully be called FAH's Website maintainer. Somebody has made some changes recently ... some good, some not so good. (Some links are now broken.) The Linux install page has not been updated in a number of years.

craig110 · Post by **craig110** » Sun May 02, 2021 3:56 pm

Well, not having a website maintainer for a while certainly explains the problem and thanks for letting me know that the website is, albeit slowly, being brought up to date. If I may suggest, far easier than fixing the FAQ installation page to automagically point to the current version, how about asking the maintainer to just, for now, add a blurb above the FAQ's Linux directions to boldly say "Warning, these instructions are very outdated. For now, please see the 'Start Folding' section to install the latest version of the software."
