Evidence

Note that this ‘C2C’ is not related to NVLink, but Groq’s own scaleup fabric

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

此處的 C2C 與 NVLink 無關，而是 Groq 自有的 scale-up fabric。

• Epistemic Mode: ASSERTED
• Mapping Status: COMPLETE

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
• 最後選擇 review_action
