SUMMARY
This article will provide more information about Multi-GPU support in Nuke.
MORE INFORMATION
Our documentation specifies that Multi-GPU processing is available for Windows, macOS and Linux for identical GPUs in the same machine (for example two NVIDIA Quadro P4000s or two AMD Pro W7900s). However, Nuke will recognise whether you have more than two identical GPUs and will allow you to use all of them.
For example, a machine with two NVIDIA Quadro P4000 cards will show the following when a ZDefocus node is created:
PLEASE NOTE: Nuke is not currently tested against setups with more than two GPUs meaning that Multi-GPU processing in Nuke is supported for machines with two identical GPUs only.
Additionally only some GPU accelerated nodes will benefit from having multiple GPUs, other GPU accelerated nodes will not, and nodes which aren't GPU accelerated will see no difference. For example MotionBlur, Kronos, OFlow, VectorGenerator nodes only work on up to 2 GPUs, VectorBlur, SmartVector, VectorDisort and CaraVR nodes only works on 1 GPU and the ZDefocus and Convolve nodes should work with any number of GPUs.
