Nvidia Disagg Prefill and WideEP

Evidence

Recall that Nvidia’s servers have two separate networking domains – the scale-up NVLink domain

Context After

NVLink domain (within the NVL72 rack): 72 GPUs connected via NVLink with 900 GB/s uni-directional bandwidth per GPU. This is roughly 7-10x the bandwidth of the InfiniBand/Ethernet based scale-out network.

② Atomic Claim

需要注意，Nvidia 的伺服器有兩個分離的 networking domains，其中之一是 scale-up NVLink domain。

  "context_nodes": [
    {
      "id": "04_knowledge_base/NVLink",
      "label": "NVLink"
    }

  },
  "value": {
    "numeric_mentions": [],
    "value_text": "需要注意，Nvidia 的伺服器有兩個分離的 networking domains，其中之一是 scale-up NVLink domain。"
  }
}

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	Nvidia	NVDA
context_0	NVLink	NVLink

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
