Building HANAMI's Workflow for Cross-Platform Climate Model Replicability

Automated workflows have become essential tools for managing the complexity of modern climate simulations across High-Performance Computing (HPC) platforms. This seminar introduces the development of HANAMI's workflow, built upon Autosubmit, a light-weight python workflow manager designed for orchestrating complex climate experiments. I will present our approach to automating the compilation, simulation and monitoring of climate model simulations across Japanese (Fugaku) and European (Marenostrum5) HPC infrastructures. The workflow aims to streamline common challenges in multi-platform execution, including job scheduling, dependency management, and resource allocation. By establishing standardized procedures for cross-platform simulation deployment, this work lays the foundation for future replicability testing and validation of climate models.
