In-Network Collective Operations: Game Changer or Challenge for AI Workloads?
🤖 AI Summary
This study systematically investigates the acceleration potential and deployment challenges of In-Network Collective (INC) operations for AI workloads. Focusing on Edge-INC and Core-INC architectures, it presents—for the first time—a clear technical roadmap accessible to non-experts, along with a comparative architectural analysis, performance modeling, and identification of key obstacles, covering both node-level and switch-embedded implementations. The work demonstrates the significant advantages of INC in enhancing the efficiency of collective communication in AI systems, delineates the distinct application scenarios suited to each paradigm, and distills six critical challenges and emerging trends. These insights offer valuable guidance for interdisciplinary research and engineering practice in next-generation AI infrastructure.
