The Shell Awakens: Cloud Native Workflows for Particle Ph... Raulian-Ionut Chiorescu & Hannes Hansen

This talk, presented by Raulian-Ionut Chiorescu and Hannes Hansen from CERN, explores how high energy physics users at CERN adapt to containerized and cloud-native computing while maintaining familiarity with traditional workflows. The speakers demonstrate how CERN integrates Kubernetes-based GPU resources into existing command-line environments, utilizing ContainerSSH to provide users with a terminal-like experience within isolated pods. The session covers unifying interactive and batch jobs, highlighting support for tools like notebooks, VSCode, Kubeflow for machine learning, and CI/CD integration with GitLab or GitHub. Additionally, it discusses advanced features such as fair-share scheduling, backfilling, and hybrid extensions through MultiKueue and interLink, showcasing CERN's approach to combining high-performance computing with cloud-native agility.
