使用 Ray LLM Deep Learning Containers 在 Amazon EKS 上运行多节点推理工作负载
AWS 发布面向多节点部署的 Ray LLM Deep Learning Container,可在 Amazon EKS 上把单个大语言模型跨两个 GPU 节点部署,并将 prefill 与 decode 阶段分离在各自节点上,统一暴露一个 OpenAI 兼容端点。该容器内置 vLLM、Ray Serve LLM、NIXL 与 EFA 通信栈,通过 build_pd_openai_app 用一段 YAML 完成服务配置,无需编写应用代码。

suited for workloads such as Retrieval Augmented Generation (RAG), document summarization, and agentic applications. We use the multi-node Ray LLM DLC, which ships Ray Serve LLM, NVIDIA Inference Transfer Library (NIXL), and the Elastic Fabric Adapter (EFA) stack, and exposes an OpenAI-compatible API with no application code. The complete code is available in the accompanying repository. Why prefill/decode (PD) disaggregation LLM inference has two distinct phases. Prefill processes the entire i
