① SA Source

Context Before

CPO scale-up will be used to build the larger world size, connecting between the racks in a two-tier all to all network, though scale-up inside the racks will remain copper-based.

Evidence

When we reach the Feynman Generation, CPO usage will expand via another large world size rack, the NVL1152 which is formed by combining 8 Kyber racks.

Context After

While the Nvidia Technical Blog that outlines the rack configuration roadmap states that “NVIDIA Kyber will scale up into a massive all-to-all NVL1152 supercomputer using similar direct optical interconnects for rack-to-rack scale-up”, Jensen Huang in a Financial Analyst Q+A session did say that NVL1152 in Feynman would be “all CPO”. There is some disagreement on whether copper will still be used for scale-up within the rack or whether CPO will replace copper.

② Atomic Claim

進入 Feynman generation 後,CPO 的使用會擴展到另一個大型 world-size rack:NVL1152,由 8 個 Kyber rack 組成。
