Missing GPU broke software 7.6.13

Posted: Mon Aug 31, 2020 12:50 am

I used to have 2 GPUs. I shut down computer, remove a GPU from inside the computer, and turn on with just 1 GPU. Now, folding at home went mostly broken. FAHControl have endless connecting and updating loop and is mostly blank. Can't delete missing GPU in FAHControl. The web control, after waiting for more then 5 minutes, eventually shows as disconnected.

Failing to connect from missing GPU also happens in windows device manager, disable any GPU in windows device manager and restart folding at home software.

Slow fix: End task Folding at Home software, go to %appdata%\FAHClient, edit config.xml, delete a GPU, save changes.

I would like to see some fix to FAHControl fail to connect over missing GPU, to speed up fixing the settings using FAHControl.

Code: Select all

May I suggest that you open up an issue on GitHub: https://github.com/FoldingAtHome/fah-issues/issues as a feature enhancement?

Generally speaking, any physical change of the GPU*, might trigger the client and fixing it can be a bit of a challenge. A fresh installation can be the quickest path assuming that it was planned which means that you set your slots to finish.

*For those who would like to know:
Switching GPU vendors -> Fresh installation is the safest option.
Upgrading GPU -> Ensure that you finish your GPU Slot and then upgrade.
Removing GPU -> Ensure that you finish your GPU Slot and then delete it.
Adding GPU -> Fresh installation is the safest option.

Of course, that's the behavior with V7.6.13 which isn't an indication of future client versions. Getting GPU detection to work correctly across different platforms and drivers isn't an easy task :(
