During January 2025, Vasco Mueller enhanced the FESOM/fesom2 repository by delivering cluster readiness and enabling Fortran MPI support for scalable workloads on the Juwels HPC stack. He updated environment configurations to ensure compatibility with newer software versions, streamlining deployment and reducing friction for users. By modifying CMake build scripts, Vasco enabled linking against the MPI Fortran library, allowing FESOM2 to leverage parallel processing through Fortran-based MPI communication. His work focused on build systems, environment management, and cluster computing, utilizing Bash and CMake. The contributions addressed deployment challenges and expanded the project’s parallel execution capabilities, demonstrating solid depth in HPC engineering.
