Thanks for sharing! I had come across similar kinds of issues on my annual LeetCode prep and this very clear articulation is very helpful. Props to the author for making this so easy to visualize.
I made my own distributed render orchestrator that supports Cycles + custom plugins. It uses Modal’s cloud compute APIs to spawn jobs on up to 20x containers with an L40S GPU (like 80% as fast as a 4090 with tons more VRAM) each. It ain’t cheap but it’s absurdly fast, and much easier in terms of cash flow than outright buying the equivalent GPUs.
