Could you build this?
No The core contribution is a novel research technique for identifying individual GPUs from atomic operation ordering, which requires original GPU-architecture research to make robust.
What it would actually take: Reproducing the basic effect is simple, but a reliable version needs an understanding of GPU memory-ordering and scheduling behavior, careful statistical evaluation across many identical devices, and robustness testing across drivers and containers. This is a research-level task for GPU systems researchers.
