Nvidia's CPO Roadmap - Line hint:
239
Context Before
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.
Evidence
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”.
Context After
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
Nvidia Technical Blog 表示 Kyber 會透過 direct optical interconnect 做 rack-to-rack scale-up，擴展成 all-to-all NVL1152；但 Jensen Huang 在 Financial Analyst Q+A 表示 Feynman 的 NVL1152 會是「all CPO」。
