Context Before

Source: SemiAnalysis

Evidence

In NVL36x2, it only takes 1 hop to get to any of the 36 GPUs within the same rack but in order to talk to the other 36 GPUs in the rack beside it, it takes 2 NVSwitch hops to get across the racks.

Context After

Source: SemiAnalysis

② Atomic Claim

NVL36x2 中，同 rack 的 36 顆 GPU 需 1 hop；跨到相鄰 rack 的另 36 顆 GPU 則需 2 個 NVSwitch hops。

entity	NVL36	NVL36
context_0	GPU	GPU
context_1	NVSwitch	NVSwitch

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
