How do I isolate work to just the GPU?

Post by Greg_BE »

I am primarily a BOINC user, so right now while my system can handle the combined crunching of FAH and BOINC, I am finding my water cooling is not able to cool fast enough despite the best fans on the radiator and one of the best cooling systems out there.

So how do I block work from the CPU and just allow the GPU to do work? Would that be to take away the slot command related to the CPU and just leave the GPU?

Removing the CPU slot will decrease FAH's need for heat-producing CPU resources. The heavy computations will be performed on the GPU (which will now get hot). A single CPU thread will always be needed to shuttle data between main RAM and the GPU's internal RAM but it should be much more limited.

If you are running FAHControl, it would be nice if you selected FINISH for the CPU assignment you're currently processing. It will finish processing, upload the result and avoid receiving a new assignment. (Unlike BOINC, FAH doesn't automatically send duplicate work to different people so "lost" WUs must time-out before they're reassigned.)
