I would like to render an animation on a remote compute cluster with several GPUs. The machine I configure the .blend file on is a laptop on which I cannot enable the User Settings>System GPU compute device setting
on my laptop. But unfortunately this doesn't seem to have any effect on the remote cluster: Rendering doesn't use the GPU (I checked with
nvidia-smi) but uses all available CPU threads. I figured the
GPU compute option is greyed out since the laptop I set the scene up with doesn't have a supported GPU to run on. But the machine I render on does.
Unfortunately there is also no way for me to start a graphical session on the remote cluster (blender in GUI mode) so I could change the User settings or confirm the render settings before I render.
I understand that I cannot set GPU rendering from the command line but is there maybe some other way I can setup a .blend file on a machine without GPU to render on the GPU when it is executed? For example: is there a way to start the render with a python script that forces the GPU option before starting the render process?
Thanks a lot for any hints on this!
