Folding Forum

@pannu: Would you be willing to be pulled into the core dev testing slack? If so, DM me your email address and we'll invite you to help track this down.

Thanks so much for bearing with us!

There is a Linux driver from NVidia, that is v450.80.02 that he can try updating to as a last result.... But let me do a quick Google search and post it in another reply, so perhaps we can sort this out together. I want to know if that is an NVidia driver or hardware generated error.

This is one result I found that was related to an AMD GPU with the same error message, on Github (see: https://github.com/FoldingAtHome/fah-issues/issues/1570).

So... this is looking like something the core development team may be able to sort out.

Try: --disable-cuda

iirc it has been posted elsewhere (by mod?) that both - and -- work ... but I guess worth a try?

Yep, these both will result in exactly the same behavior in Windows and Linux:
-disable-cuda
--disable-cuda

Fun fact, virtually all arguments (that I have used) for FahCore_XX supports single and double dashes. That has been true for many years

I've seen them written both ways, but used the latter version temporarily till I got my NVidia carded legacy systems humming on Linux (Fedora 32).

BTW: Is there a method to update the NVidia drivers, w/o having to go back through the clean install process that I have been using in Fedora? Last time I used the RPM manager in Gnome, I lost the ability to fold w/the GPU.

Paul

I used the Additional Drivers to update drivers when I needed it: https://askubuntu.com/questions/47506/h ... al-drivers

Ok, I don't think that process will help me much as I am using Fedora (which is a Red Hat based distribution).

Thank you for your efforts though.

Commenting out that single line in /etc/Opencl/vendors/pocl.icd fixed it for me too. GPU is folding again (with CUDA). Github issue 1570 is likely on right track.

Happy to know I was able to put you on a good path to resolving this.

This also got all three of my Fedora 32 with Nvidia GPU's back to folding. Thanks you for this posting.

Sorry for the me too post, but I've had the same problem for quite some time, across kernels, drivers, and even full versions of Fedora. I ended up removing the pocl package because it didn't seem to have any dependencies I really need, now the GPU works.

As I speak, I'm waiting for 1 GPU task to finish on my one Fedora 33 system, before I do the 'dnf update' process (as Admin from terminal). With all of the recent Linux dependency changes, I want to make sure I still have working OpenCL & Cuda support when I reboot.

Note: It will be around 2:50 AM/0750 GMT when I do this, so I'm prepared to make more coffee should it be needed.

I am having the same issue with the latest Nvidia drivers. 1060 card on Ubuntu 20.04.1
upd: commenting line in /etc/OpenCL/vendors/pocl.icd helped.
