Context Before

Source: SemiAnalysis AI Networking Model ↗

Evidence

For a 512-port switch, we can connect up to 131,072 GPUs with two layers of switches or a ludicrous 33,554,432 GPUs on 3 layers

Context After

2(5122)2=131,072

2(5122)3=33,554,432

② Atomic Claim

對 512-port switch，使用 2 layers switches 最多可連接 131,072 顆 GPUs；若使用 3 layers，理論上可達 33,554,432 顆 GPUs。

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
