22 Sept 2025, 10:00 → 23 Sept 2025, 12:00 Europe/Berlin

Lecture Hall - 106/255 (HZDR)

Henrik Schulz, Kushal Ramakrishna (HZDR), Mani Lokamani (HZDR), Varun Sudharshnam (HZDR)

This workshop is designed to help users of all experience levels get started with ROSI. You’ll be introduced to best practices for accessing and using the cluster efficiently through Open OnDemand web interface, which simplifies many common HPC tasks such as file management, job submission, and launching interactive applications. The workshop will also highlight how ROSI can support a wide range of computational workflows—from large-scale simulations and data processing to Machine Learning & AI projects.
