V-Ray GPU Renderfarm

[landrvr1]

Forgive my ignorance, but can you send V-Ray GPU scenes to a GPU farm and have each individual GPU render separate frames? I see on the promo page that it says : MULTI-GPU SUPPORT V-Ray GPU supports as many GPUs as your system recognizes for ultrafast workflows. Not sure if that's just distributed or ....?

Tnx!

"Multi-GPU support" means that you can have more than 1 GPU on the same machine and V-Ray will use all available CUDA devices to render the scene. Your benefit is increased render speed. Why do you want to render separate frames on separate GPUs?

You can use Chaos Cloud, it takes couple of clicks to submit jobs .. it is been working nicely for us so far
it only uses bucket mode though (for the Cuda renderer), which is fine..
while the cloud is CPU based, it renders the Cuda scenes through Hybird rendering which makes it cheaper and less problems compared to GPU based render farms

As far as I know this is not supported on Chaos Cloud, you will need to render a frame per machine
but Vray supports distributed rendering of the same frame across several machines.. if you have your own farm for example or if there is a GPU farm that supports that

You can render different frames on different GPUs You`ll need advanced render manager as Deadline to be able to submit jobs like that. Deadline is able to manage GPU affinity. For example, if you have 3 GPUs on single machines you can run 3 slaves at the same time, and each one will have assigned specific GPU. When you submit 100 frames job, each slave will pick different frame, rendering 3 different frames on 3 GPUs at the same time.

Here is GPU affinity settings from deadline submitter for 3D Max, you can find similar in Maya, Houdini etc.

Thanks everyone. psanitra, that's exactly what I'm looking for...! We do mostly animated films. Our use case would be: Create the arch viz scene with animated camera, render out to a GPU array: 1 frame rendered by 1 GPU x as many GPUs as we can muster. Sounds like Deadline is just the manager we need ot handle that...?!
Am I thinking of this in the right way? Is there another approach?

This is another cool tool, by Alex kurcera
it does exactly the same job
