Turn Rosetta@Home into a gpu-only project if you toggle it off? I would think since it doesn't use a GPU it would stop you from processing Rosetta work. Why is it there? Because at some stage there may be computation devices other than CPU or GPU and you may wish to use that as yet not invented device but not your CPU is my guess.

I have toggled it off to see if any gpu tasks will show up. I don't expect any to based on reading other threads where gpu processing was not shown to be efficient on this project. If R@H tasks dry up below the 18 or so I am running then I will be able to experimentally confirm there are no gpu tasks for running on Rosetti. :) ==edit== There are 68 tasks in there right now ===edit=== Tom Help, my tagline is missing.....

I have toggled the "use cpu" back on. And I expect the cache to replenish. Tom M Help, my tagline is missing..... Help, my tagline is......... Help, m........ Hel.....
