Disaggregated Prefill and Decode for LLM Inference on HyperPod

The article focuses on a technical optimization for Large Language Model (LLM) inference, specifically demonstrating the implementation of Disaggregated Prefill and Decode (DPD). This technique is shown in conjunction with vLLM, a high-performance inference engine, deployed on Amazon SageMaker HyperPod. The core of the demonstration involves utilizing the HyperPod Inference Operator to effectively manage and execute this optimized inference process. The goal is to improve the efficiency and scalability of LLM serving by separating the prefill and decode phases of token generation.
