This session brings together three years of collective experience from the DataNexus cluster working on extreme data challenges. Four flagship projects from the cluster will showcase the value and impact of their technologies and solutions. Participants will discover how these projects have pushed the boundaries beyond the state of the art and will learn which components, platforms or datasets are being made available-including where to access them. EXA4MIND, EXTRACT, Graph-Massivizer and NEARDATA will present real-world case studies demonstrating how next-generation workflows, AI integration, and high-performance data platforms are creating tangible impact across domains, from energy and manufacturing to smart cities and crisis management.
