Force GPU rendering python script

Description

In our quest to get our GPU workers to use all available GPU's we have found a script.

This script doesn't work when added to the script>startup directory. We don't know why.

But, when added to the commandline in the yaml file of the manager it works perfectly.

Add this to the commandline. --enable-autoexec --python "S:/-location script-/gpurender.py"

gpurender.py is below script.

import bpy
bpy.context.user_preferences.addons['cycles'].preferences.compute_device_type = 'CUDA'
bpy.context.user_preferences.addons['cycles'].preferences.compute_device = 'CUDA_MULTI_2'

Our request is to have this be added in the flamenco worker code or something. And have a checkbox somewhere to enable this feature..

We hope it helps!

With kind regards,

Something like this should work:

import bpy

scene = bpy.context.scene
scene.cycles.device = 'GPU'

prefs = bpy.context.user_preferences
cprefs = prefs.addons['cycles'].preferences

# Attempt to set GPU device types if available
for compute_device_type in ('CUDA', 'OPENCL', 'NONE'):
    try:
        cprefs.compute_device_type = compute_device_type
        break
    except TypeError:
        pass

# Enable all CPU and GPU devices
for device in cprefs.devices:
    device.use = True

Thanks @Brecht Van Lommel (brecht)!

@joel heethaar (joel_nl) I've added Brecht's script to Flamenco Worker, to the T53099-gpu-rendering branch, but I haven't created anything around that yet. Can you test that the script works by adding --enable-autoexec --python "/path/to/flamenco-worker/flamenco_worker/enable_all_gpus.py" to the blender variable in your flamenco-manager.yaml?

Adding the script to my blender variable in flamenco-manager.yaml works for me.
