LLM推理优化:Prefill-Decode Disaggregation详解

一篇最新的技术文章探讨了用于优化大型语言模型(LLM)推理的Prefill-Decode Disaggregation概念。该技术将计算密集型的提示处理(预填充)阶段与内存密集型的令牌生成(解码)阶段分开。通过为每个阶段分配不同的硬件,例如为预填充使用强大的GPU,为解码使用内存优化的GPU,可以实现75-250%的显著吞吐量提升。然而,这种方法会增加复杂性和运营开销,因此它最适用于提示长度可变、并发度高且对令牌间延迟要求较低的工作负载,而不是小规模的批处理。 AI

影响 这项优化技术可以显著提高特定工作负载的LLM推理吞吐量和延迟,从而可能降低运营成本并改善交互式应用中的用户体验。
