High-performance computing (HPC) research thrives on collaboration, yet institutional data silos often hinder progress. This extends beyond the storage hardware itself to where data is being siloed in departments and institutions alike. Accelerating scientific progress and innovation requires enabling secure data discovery and sharing across not only institutions, but scientific disciplines as well. Federated access models, controlled permissions, and distributed compute environments enable seamless yet secure collaboration. By facilitating data discovery across disciplines and optimizing shared infrastructure, organizations can break down barriers, enhance research efficiency, and drive cross-disciplinary insights that push the boundaries of scientific advancement.
