One small correction to the article is that the peer-to-peer feature will be used with Gaudi devices, not Goya, because you need to use p2p to perform training on tens or hundreds of Gaudis. Inference doesn't require connecting between multiple ASICs.
Now, we can connect Gaudis using the internal NICs of the Gaudi, but the customer can opt using an external RDMA adapter to connect between Gaudis (or more accurately, between boxes of Gaudis, because inside the box the internal NICs are always used).
