Context Before

The LPU network can be divided into the scale-up ‘C2C’ network and

Evidence

scale-out network which interacts with the Nvidia GPUs through Spectrum-X.

Context After

First let’s discuss the scale-up network which can be divided into 3 portions: intra-node, inter-node/intra-rack, inter-rack. For C2C within the rack Nvidia announced a total of 640TB/s of scale up bandwidth per rack which comes from 256 LPUs x 90 lanes x 112Gbps/8 x 2 directions = 645TB/s.

② Atomic Claim

scale-out network 會透過 Spectrum-X 與 Nvidia GPU 互動。

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
network	scale-out network	04_knowledge_base/Scale-out networking
gpu_vendor	Nvidia	NVDA
compute_device	GPU	GPU

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
