Folding Forum

Hello.

When I remove the GPU slot and save then it is re-added after restarting F@h. Is this intended behavior?

Yes, it is. There are a number of ways on how to deal with this. Personally, to avoid GPU folding starting automatically, I added the option 'pause-on-start' with value 'true' to the advanced options, in FAHControl. You can set that for the entire client (so would apply to all slots, both GPU and CPU), or you can add it for per slot where you want to apply it.

Thanks. There is a difference between pausing and removing the slot, though. A paused GPU slot behaves the same as my currently unpaused forever-connecting GPU slot, both cause the CPU slot to only run at 97% instead of 100%. Only removing the GPU slot allows the CPU slot to run at 100%. It's not a problem for me personally (I even abuse it for CPU stability tests), but worth mentioning.

I used to frequently advise folks to completely uninstall F@H and reinstall it to get new GPUs to be discovered. Making it search for GPU changes on start up solved that.

If you want help running the GPU, you could post the first 200 lines of the log.
If you want 100% CPU utilization, you can set the number of actve CPUs in the advanced client (configure, slots, CPU, move the number from -1 to the real number)

F@h already uses the correct number of threads. But when a GPU slot is paused (either manually or due to connection issues) then the CPU slot threads don't run at 100% (but around 97% instead). Deleting the GPU slot entirely allows the CPU slot to use the full 100%. It's just an observation, I can work with this.

In FAHControl, client options, add option gpu false.
This should prevent the client from recreating GPU slots.

Thanks, this works and is useful to know for future use.
