Running folding-at-home-fcole90 many such errors appear

11:07:36:ERROR:Exception: Failed to open '/sys/class/power_supply/AC/online': Failed to open '/sys/class/power_supply/AC/online': Permission denied: iostream error: Permission denied

Clicking the project number in FAHControl doesn't do anything.
I realize it is a really small issue, but I like to know what it is caused by.

System: snapd 2.45, series 16 on linuxmint 18.3 and kernel 4.15.0-101-generic

Hi, I'm using ubuntu 19.10, downloaded FAHClient directly from Ubuntu X11 application. I'm using a Nvidia GTX 1080 with Nvidia driver (coming from original website.
Ubuntu is fully up to date. I also installed ocl-icd-opencl-dev package but still got this error.
I tried to modify the FAHClient script to make it using root user instead of fahclient (i found in some tread the suggestion to use root) but got error no read only file system.

I'm sorry but I don't know how to change snap environment/files
Have you tried to run the script as different user already?

Anything else I can try? Thanks

Potential font issue on Manjaro GNOME. Font shows up as blank boxes. Interface is still functional, and folding seems to be progressing just fine based on CPU usage. Screenshot attached.

In FAHControl, in logs, there are many lines saying:

Failed to open '/sys/class/power_supply/AC0/online': Permission denied: iostream error: Permission denied

I think it is trying to check if the laptop is plugged in, in order to determine if to compute or not.
Adding the upower-observe plug, didn’t change the outcome.

I've edited ~/snap/folding-at-home-fcole90/common/config.xml to allow another pc on my network web access with and

If I restart my fah server and try visit the fah webpage, I get access-denied.

I then run:
"sudo snap stop folding-at-home-fcole90"
and
"folding-at-home-fcole90"

Then I can access the fah webpage from my other pc.

How come when I restart my pc (so it's using default snap stuff) it doesn't allow the ips in the config.xml?

Installed the F@H app from the Ubuntu store. Client is running fine but I have the following issues:

• only have the F@H control, i.e unable to launch the web interface.

• In the app control, when going to configure > advance, COVID-19 is not listed in the "Cause Preference" drop down menu.

• I have two "Folding At Home " icons in my app list as shown in the attached image. when I click on either I receive an error - "Failed to Launch Folding at Home - Desktop file didn't specify exec field"
  

Sometimes FAHClient starts computing, for no apparent reason. I think it might have something with the restart-condition: on-failure that is set for its daemon but I’m not sure.

Hi Fabio,

I am having GPU detection issues on Debian 12 Bookworm and current gen hardware (Ryzen 7950X and an RTX 4070ti).

More precisely F@H created and disabled slots on both the iGPU and the main GPU (the slot CPU is properly created and active).

In the "System Info" tab I get:
"CUDA Not detected: Failed to open dynamic library 'libcuda.so': libcuda.so: cannot open shared object file: No such file or directory" and "OpenCL Not detected: clGetPlatformIDs() returned -1001"

The NVIDIA drivers are correctly installed and include libcuda.so (along with several links of the same name pointing to it from various locations throughout the system).

At the first install of the SNAP package I had not seen the command for proper GPU detection so I got the issue. That's when I found the command and ran it but it did not correct anything, so I also "refreshed" the SNAP but the problem remained. I then uninstalled the SNAP, deleted the entire /Home/snap/folding-at-home-fcole90 folder, reinstalled and immediately re-ran the command for GPU detection, but I still have the issue.

Any idea of how to get CUDA detected and the main GPU to fold? Was there another folder I should have deleted to fully remove the F@H config when I uninstalled? Do I need to create a "libcuda.so" link anywhere to point to the location of the CUDA install?

Thanks,
Christophe

Thanks for the package. It looks like a minor issue.
Version: folding-at-home-fcole90 7.5.1
Revision: 16

ls -la ~/snap/folding-at-home-fcole90/current/

There is no data-dir.

First of all - thanks for enabling folding on newer Ubuntu devices!

After a reboot the folding starts and proceeds just fine, no issues, all good. However, after a while, it cannot start a job and continues to get new WUs indefinitely.

The errors it throws out are:

opencl-device was set but OpenCL platform could not be found.

failed to create a gpu enabled openmm context

Thanks!

Gtk-Message: 03:36:16.113: Failed to load module "appmenu-gtk-module"

In the FAHControl, checking System Info, for OpenCL it says

Not detected: Failed to open dynamic library 'libOpenCL.so': libOpenCL.so: cannot open shared object file: No such file or directory

However if I look for OpenCL vendors I can find the them

snap run --shell folding-at-home-fcole90.FAHClient
fabio@fabio-X550JK:/home/fabio/scratch/folding-at-home$ cat /etc/OpenCL/vendors/nvidia.icd 
libnvidia-opencl.so.1

It is possibly missing some symlink.

When I install folding@home snap on computer, it looks like this:

System: Manjaro Linux KDE

What happens?

sudo /etc/init.d/FAHClient start -v
Starting FAHClient . . . /etc/init.d/FAHClient: line 120: /usr/bin/FAHClient: No such file or directory

What should happen?

The FAHClient should start

Steps to reproduce

Attempt to start FAHClient via init.d

• Command is in the "What happens?" section

Additional system information

Ubuntu 19.10 (Eoan)

• 5.3.0-42-generic #34-Ubuntu SMP Fri Feb 28 05:49:40 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Notes

Inside the init.d script:

022: EXEC=/usr/bin/FAHClient
⋮
120: $EXEC $OPTS &

yet, when installed as a Snap package it looks like the binaries are installed in a sandboxed location — e.g.,

/snap/folding-at-home-fcole90/5/usr/bin/FAHClient

• So it looks like — at minimum — the init.d script would need to be updated to use the binary installation locations for the Snap package.

Suggestions

• May want to consider making the startup process more Ubuntu-like:
  • Port the FAHClient launch script to a systemd service unit — e.g.,
    • Install Folding@home FAHClient on Linux as a systemd service unit
