AskHPC: A ChatBot for High Performance Computing User Support
DescriptionHigh-Performance Computing (HPC) systems in the exascale era are increasingly heterogeneous, requiring users to navigate diverse tools, configurations, and best practices. However, essential information is often scattered across fragmented, multimodal documentation, making it difficult and time-consuming to locate. To address this, we present AskHPC, an intelligent question-answering ChatBot that delivers accurate, timely, and accessible information through a unified conversational interface. Built on a curated knowledge base integrating user guides, scheduler manuals, and programming documentation, AskHPC leverages Large Language Models (LLMs) within a Retrieval-Augmented Generation (RAG) framework. It employs two key techniques to improve HPC query responses: a modality-aware document parsing pipeline that preserves multimodal structure, and a dual-context strategy combining retrieved content (e.g., complete code blocks) with LLM-generated semantics. Evaluation, including a real-world user study, shows AskHPC outperforms direct LLM queries and vanilla RAG systems, enhancing user support and accelerating HPC software development.
