关键搜索片段(Google AI 摘要)

搜索: "long context" "PD disaggregation" challenge 2025 blog

Google AI 摘要原文 (越南语界面):

> Prefill-Decode (PD) disaggregation splits an AI model's prompt reading (prefill) and token generation (decode) into different processes. While it helps process millions of context tokens, the "long context" and "PD" challenge stems from **GPU memory starvation** and **massive KV cache (memory map) transfers** between servers.

>

> The main challenges in modern LLM infrastructure include:

> - **Bandwidth Bottlenecks**: Long-context prompts create massive amounts of memory state (KV Cache). Moving this cache from Prefill nodes to Decode nodes across the network creates severe traffic congestion and latency.

> - **Resource Mismatch**: Prefill is highly compute-bound, while decoding is memory-bandwidth-bound. Balancing these two workloads without idling GPUs is difficult.

> - **Head-of-Line Blocking**: Massive long-context requests take a long time to read, blocking smaller requests behind them in the queue and causing system timeouts.

搜索: "million token context" LLM serving

Google AI 摘要:

> Serving multi-million token contexts requires solving the **Prefill Bottleneck** — processing the massive initial prompt — and managing the **KV Cache**, which is the memory required to store the model's "attention" memory for every single token.

>

> A 1-million-token input can require **tens of gigabytes of expensive GPU memory per user**. Without proper serving infrastructure, memory runs out quickly, or the system experiences a long freeze (latency) before generating a response.

搜索: KV cache compression "disaggregated" "long context"

Google AI 摘要:

> KV cache compression in disaggregated long-context LLMs solves a major data bottleneck. In modern systems, generation (decoding) runs on different hardware than initial reading (prefilling). Passing huge amounts of historical data (the KV cache) between them slows everything down.
