I have a Mac Pro with 2 GPU installed:

nVidia GeForce 8800 GT
nVidia GeForce GT 120

How to I set BOINC to Use GPU Always on the former, but Use GPU based on Preferences on the latter when the computer's idle...?

Thanks.

Set BOINC to identify 2 GPU with different priorities..?

When a recent BOINC client finds two CUDA devices that differ in capabilities, it will ignore the less powerful one completely (message says 'not used'). Older clients will treat all CUDA devices equally and report the properties of device #0.

Different settings for different CUDA devices aren't provided for in the standard BOINC client. You are, however, free to implement them and compile your own client.

What Bernd is saying is that both gpu's need to be the same if you are going to crunch with them! If you are just using them as video cards it makes no difference, but when crunching it does.

No, he is not! He says that you can't set different preferences for each card.

If you want to use more than one GPU (equal or not) you have to set up a cc_config.xml with set to true.

And that, in turn, is slightly misleading! (though appropriate for the current case.)

If the two cards are "close enough" in performance (within 30%), BOINC will use them both anyway. It's only the asymmetric case that needs .
