Yes and no. There is only one functionality - training of deep learning (Accelerating compute operations) :) The rdma is just our method of scaling-out - our method of intra-connection between GAUDI devices (similar to NVlink or AMD crossfire). So the H/W exposes a single physical function at the PCI level. And thus Linux can call a single driver for it during the PCI probe. I hope that in future generations we will improve that, but it is what it is for GAUDI. I don't see how to do it otherwise currently but if you have ideas please share. Oded
