How to make both CPU and GPU work on the same work unit?
Is it possible to set the client to use both my CPU and GPU to process the same work unit? If different cores of a CPU can be altogether assigned the same work unit, I think it will be possible to also add the GPU to the whole complex and use them all for processing one work unit at a time. But I could not find a way to do that. Perhaps this might be done by configuring client folding slots in the Advanced Control?
I am asking this because my GPU work units keep expiring unfinished (at percentages below 10%). So all its processing power is going to waste. It would be much better if my GPU could help the CPU, instead of working on a separate work unit that keeps expiring.

Re: How to make both CPU and GPU work on the same work unit?
Using the current folding cores this is not possible. A future folding core might support this, but balancing the resources which are different between CPU and GPU will not be easy.

Until this possibility eventually appears, it would be better to disable your GPU slot.

Disabled it, thanks. Hope this feature gets implemented in the future.

Re: How to make both CPU and GPU work on the same work unit?
I keep removing the GPU slot; but every time I close the core and re-open it (for example, after each computer restart), the GPU slot is back there and active! Is there a way to remove it permanently?

I don't have a link. Someone else might.
Interesting options include
next-unit-percentage 100
pause-on-start true
You can see tons of options with
But most options are actually internal things you should NOT change.
