When you install the daemon, you can specify which GPUs should be used.

Hi coilbook,
you don't need to specify the model of your GPU but the number of GPU, from 0 to 2 in your case. From the manual:

Code: Select all

-g <int>,  --gpu <int>  (accepted multiple times)
 add GPU device to use for rendering (0 = first)

hi i still cannot get it to work. Could you tell me exactly what to type to get two secondary video cards to be used and the top one on the motherboard not to use thank you

Itypes 1, 2 and it used primary one and the third one on the motherboard If i type anything else like 0,1 or 0, 2 Slave just wont run



it says which GPUs should be used Please keep default or enter a coma/space separated list"

Please post a screenshot of the device tab (File -> Preferences... -> Devices) of the Standalone on the slave and highlight all device that should be enabled. I will then let you know what to enter during the daemon installation.

All GPUs are connected to the motherboard. You probably mean the GPU that is not connected to any displays. There is no way I know of, that would allow Octane or me to figure out which GPUs are used for displays. The only way would be to enable each, render a complex scene and see for which GPUs the GUI performance drops noticable.

Anyway, the daemon installer asks for a list of GPUs that should be used by the slave. You have 3 CUDA GPUs so the possible GPU indices are 1, 2 and 3. If you want to disable GPU 1, you would enter 2,3. If you want to disable GPU 2, you would enter 1,3.
