Research: every GPU leaves a fingerprint in floating-point math

A new writeup shows a default torch index_add_ call can identify the exact GPU it ran on, even among identical cards, because each chip sums floating-point numbers in its own order. The fingerprint survives reboots and can't be faked; PyTorch developer @cHHillee called it the first new thing he's learned about GPU...
