Arnold GPU Affinity

Is it possible to add GPU affinity for Arnold?

Submitting to 8x GPU box with 1x worker uses all cards, but splitting into 4 workers with 2 cards each crashes the machine. Running 1/4 workers shows the job is still processing on all 8 cards.

CUDA_VISIBLE_DEVICES
This env var is on the docs, but seems a bit global

I sent a ticket to SolidAngle and they said it works like this
kick -i /mnt/path/to/your/scene.ass -device GPU -gpu 0 1

So it should be possible to incorporate this into the Arnold standalone and application plugins?

— update —
I have a ticket open for this (107936), Thinkbox are aware of this and hopefully will be integrated in the future
