[Bf-cycles] Multi-GPU tiling support?

[Brecht Van Lommel]

Yes, 6x6 tiles should allow 36 GPU's to work on the same image. But
even before the tiling multi GPU was already working. So more likely
it has something to do with the configuration or Cycles not
recognizing the GPU's. Cycles should by default use all GPU's except
for the one used for display in case of multi GPU. So if this is a
dual GPU system that might be the problem that causes only one of the
two to be used.

This script can be used to print which GPU devices is used and which
settings are available, if you have some way to run.

Ideally the render farm should set things up such that the user
preferences are already saved with the right configuration.
