Balancing Scale and Responsibility in Training Massive AI Models
Introduction to Large-Scale AI Model Training The development of artificial intelligence models with billions or even trillions of parameters is a significant step forward in AI capabilities. However, training such massive models demands complex parallel computing methods and careful resource management. This challenge is not only technical but also societal, as the choices made during development affect the accessibility, fairness, and environmental impact of AI technologies. Understanding Parallelism Strategies To handle the massive size of these models, researchers must combine different parallelism approaches. Data parallelism splits the input data across processors, while model parallelism divides the model itself. Pipeline parallelism sequences operations to keep processors busy. Choosing the right mix is crucial to maintain speed and efficiency without overwhelming memory resources. Mistakes in balancing these strategies can lead to wasted energy and slower progress. ...
