Here I record my thoughts and insights from reading open-source framework source code, hoping they will be helpful to other developers. I will keep updating the articles in this repository; if you’d like to follow along, please give it a `star`. ## 📖 Table of Contents # 🔥 LLM | Project | Version | Article | |:-------:|:-------:|:------| |vLLM|v1 @ 6cf7b26bd|[vLLM Source Walkthrough: From `generate()` to the First Token](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/LLM/vllm/01-from-generate-to-first-token.md)<br>[Entrypoints: `LLM`, CLI, and the OpenAI-Compatible Server](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/LLM/vllm/02-entrypoints-llm-cli-openai-server.md)<br>[V1 Process Architecture: API Server, EngineCore, and GPU Workers](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/LLM/vllm/03-v1-process-architecture.md)<br>[EngineCore Loop: Request Lifecycle, Step, and Output Processing](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/LLM/vllm/04-enginecore-loop-request-lifecycle.md)<br>[Scheduler: Continuous Batching and Chunked Prefill](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/LLM/vllm/05-scheduler-continuous-batching-chunked-prefill.md)<br>[KV Cache Manager and Paged KV Cache](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/LLM/vllm/06-kv-cache-manager-paged-kv-cache.md)| --------------------------- # 🐳 Go | Project | Version | Article | |:-------:|:-------:|:------| |Go|1.16 darwin/amd64| [A Go Beginner's Journey](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/Go/new_gopher_tips.md)<br>[A First Look at How Go Compile Commands Execute](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/Go/go_command.md)<br>[In-Depth Analysis of Go Slice Internals](https://github.com/halfrost/Halfrost-Field/blob/master/contents-en/Go/go_slice.md)<br>[How to Design and Implement a Thread-Safe Map?
