I'm trying to get ready for tdp, and somehow my app config didn't quite migrate when I switched ssds. All my CPU stuff is fine (yeah, im still using app config) but I have forgotten how to set up GPU apps. I had a medical procedure today and was under general anaesthesia, so I really don't feel like trying to figure it out myself. any help would be appreciated.

I believe the default is to run 1 gpu task at a time using all or part of 1 cpu core...so you don't need one for that. The file would be for people who want to run more than 1 workunit at a time and then possibly also cut down, or increase, the cpu usage per workunit. I used to run one at another project running multiple gpu tasks at once but letting the app choose how much of a cpu core it wanted to use, the key was more workunits at one time for gpu efficiency.

You do know it's impossible for app_config to "control" the amount of CPU time that a GPU app uses, right? BOINC has absolutely no control over this. That is not the purpose of avg_ncpus in a GPU app_version block. The app will use whatever it needs to use.

At the very least, you're giving less knowledgeable readers the wrong impression when you say that.
