The article explains continuous batching, a scheduling technique that re‑evaluates the batch at every inference iteration, eliminating the straggler problem of static batching, and shows how it, together with PagedAttention, can raise LLM service throughput dramatically while balancing latency and memory usage.
This article walks through a two‑month source‑code study of vLLM, explaining how token‑level scheduling, continuous batching, and the Paged Attention mechanism reshape tensor dimensions to turn large‑model inference into a compute‑bound, high‑throughput process while managing GPU memory efficiently.
The article explains LLM inference stages, how KV‑cache and vLLM's Paged Attention enable cross‑request prompt caching, and shares practical guidelines for prompt ordering, immutable caching, and robust tool design that together shape efficient and reliable AI agent architectures.
This article explains how Paged Attention, introduced by the vLLM team, applies virtual‑memory techniques, non‑contiguous block mapping, copy‑on‑write reuse, distributed scheduling, and hardware‑level optimizations to improve KV‑cache efficiency and reduce memory fragmentation in large language model serving.
This article analyzes the challenges of deploying large language models locally and presents a comprehensive set of engineering techniques—including CPU/GPU process separation, Paged Attention, Radix Attention, chunked prefill, output‑length reduction, multi‑GPU tensor parallelism, and speculative decoding—to dramatically boost inference throughput and cut response latency.
