Feels like it's been some time since I've learned something new about non-determinism on GPUs ๐ Pretty cool!

New writeup: you can fingerprint the exact GPU you're running on with a default torch.index_add_ call, even among identical GPUs.
This works because floating-point maths depends on order, and every GPU has its own. This fingerprint survives reboots and can't be faked.
