Folding Forum

I currently use the setting "gpu false" to stop it detecting a new GPU, how do I do this for a CPU? I have a very slow CPU with 4 GPUs connected to it. I want the CPU to only be a helper for the GPUs. It manages this well, but not if it's doing it's own work.

I don't believe a similar option exists for the CPU.
I would suggest adding "pause-on-start true" to your config. This will pause all slots in your system until you are ready to manually start them.

Note:- this also sounds like the client worked correctly. When you removed your GPUs the client basically started to a blank slate, so it added the CPU.

You have a funny idea of "correctly", but I guess it won't happen again if the GPUs remain. If the user deleted something, he probably wants it to stay deleted.

I've tried "CPU false" just in case, which didn't produce an error. Is there a page listing all these parameters?

I don't like pause-on-start, it only has "off" or "on", I want "the same as before", like the setting in the BIOS for a power failure. Sometimes I'm folding and want a reboot (eg. Windows update) to allow it to continue, sometimes I'm not folding and don't want it to download tasks to run and start them without me asking.

you can use the command line to get each executable to print out every option it can use

Those are for running under the command line? I looked through the output of "fahclient --help" and it didn't include "gpu false".

It's complicated.
Most options will work in both command line and config. Some options are exclusive to one or the other, it's a game of trial and error trying to figure out which. Someone might have a definitive list, I don't. If you're using the option in command line you need to prefix it with --, the config does not require this.

We'll take the option you're looking for as an example "gpu" is the option
"<boolean=true>" this is a combination of both the type of option as well as the default
boolean = true OR false
true = the default value applied to this option
When you enter the option you simply enter the option name "gpu" and the value "true", you don't need to enter the brackets or the value type.
I do not know if this option can be set from the command line.

I think something worth noting is that the options only appear in your config when they are valid AND they deviate from the default values.

Ah, I went back into the settings and it's deleted "cpu false", so that must be an invalid thing to ask of it.
I've also seen them deleted before when I changed gpu to true, quite annoying as it's handy to remember what that setting was!
I guess one day they'll make all this intuitive....

If deleted, the CPU slot is not recreated like the GPU ones.

It might be recreated if there are no other slots, but I'm definitely not sure about this.

If there are no other slots, a CPU slot will be created. The assumption in the client configuration code is that if it is installed, folding is supposed to occur somehow. In the absence of a configurable GPU, then a CPU slot is configured.

Argh! Assumptions! The computer has no idea what I plan for it.

Neither do the developers. There was only one, now two, developers for the client and server software. You can not make the assumption they can read your mind either.

Contrarywise, I'm saying they and the client should NOT try to read my mind. No assumption should be made. It's like everything these days, computers, phones, even cars assume because you did X you're now wanting Y.

The vast majority of folders run their machines 24/7 without issue. They don't stop them mid-fold to completely reconfigure them.
The client does not know what you might do to your folding machine, only what you have done to it.
You are the only person complaining about the client deleting slots when you remove the respective physical hardware.
You are expecting the client to do things it was not designed to do.

You have talked before about your system crashing and burning every few days, now that's something worth looking at. Start another thread.
