Context Before
Source: SemiAnalysis Networking Model ↗
Evidence
Within each tray or node, all 16 LPUs are connected to each other in an all-to-all mesh
Context After
The LPU also has 1x100G going to one FPGA, with each FPGA interfacing with 8 LPUs. The 2 FPGAs each have 8x PCIe Gen 5 going to the CPUs. The LPU needs to traverse through the FPGA to interface with the CPU as LPUs don’t have PCIe PHYs to interface directly.
Inter-node/Intra-rack
② Atomic Claim
每個 tray／node 內的 16 顆 LPU 彼此以 all-to-all mesh 全互連。

⑤ Human Review
請在 Properties 逐項確認：
- 原文 → Atomic Claim 是否忠實
- Atomic Claim → Semantic Frame 是否忠實
- Canonical Entity mapping 是否正確
- Epistemic mode 是否保留原文語氣
