If you have problems with P2P in the level_zero backend then your best bet is to ask @nrspruit

[KornevNikita]

Ah, okay, got it. Moved to discussions. Please re-open the issue if needed.

@JackAKirk hi, could you please provide some info here?

This isn't possible. P2P is only possible between two GPUs from the same backend. I've clarified this in the extension document here: #15847
