The trt-llm-rag-linux project implements a Retrieval-Augmented Generation (RAG) pipeline, with the Application Orchestrator (Main Logic) serving as the central control unit. This orchestrator coordinates interactions between the User Interface and various backend components. Upon receiving a user query from the User Interface, the Application Orchestrator leverages the Configuration Loader to ensure proper application settings, the Inference Engine Generator to prepare the LLM environment, and the Vector Store Manager for efficient context retrieval. The Data Fetcher is responsible for acquiring and preparing external data for the vector store. Finally, the LLM Streamed Caller facilitates real-time interaction with the Large Language Model, with responses streamed back to the User Interface. This architecture ensures a modular and efficient flow for processing user queries and generating relevant, context-aware responses.
This is the overarching component that embodies the core application logic. It acts as the central hub, receiving user requests from the UI, coordinating the sequence of operations across the RAG pipeline, managing the application's state, and directing data flow between all integrated layers. It ensures a cohesive end-to-end process.
