Run "lspci -tv" to see what cards are installed and recognized by your system. Typically your GPUs are recognized in order of how they are physically installed: your first (usually top) GPU will be #0, your middle one will be #1, and your last (usually bottom) one will be #2.
it reconized 3 gpu. i need know whch physical card is gpu 0, gpu 1, gpu2.
