Thanks for your interest and welcome to the KDD’25 tutorial on Training Industry-scale GNNs with GiGL! This tutorial aims to provide a comprehensive introduction to Graph Neural Networks (GNNs) and their scalability challenges, while also offering hands-on experience with the GiGL library. By the end of this tutorial, you will have a solid understanding of GNNs, the challenges they face in scaling, and how GiGL addresses these challenges effectively. Most importantly, you will walk away with the knowledge and skills to train and infer industry-scale GNNs using GiGL.
