Context Before

Within each tray or node, all 16 LPUs are connected to each other in an all-to-all mesh.

Evidence

Each LPU module connects to the 15 other LPUs within the node with 4x100G of C2C bandwidth.

Context After

Note that this ‘C2C’ is not related to NVLink, but Groq’s own scaleup fabric. These connections are all via PCB trace, which necessitates an extremely high spec PCB to support this routing density.

② Atomic Claim

每個 LPU module 會以 4×100G 的 C2C bandwidth，連接 node 內另外 15 顆 LPU。
