Context Before
Essentially, this means ConnectX-8 has two hosts, Grace CPU and B300 GPU.
Evidence
This improves latency in the backend network.
Context After
However, for VR NVL72, the direct connection between Rubin GPU and ConnectX-9 is reverted back to the same design as GB200, as Rubin does not have PCIe bandwidth for two ConnectX-9. Rubin connects to Vera via C2C link, then Vera will connect to ConnectX-9 via PCIe6 lanes.
② Atomic Claim
這種設計可改善 backend network latency。
