PROFILE
Franz Pöschel
Over a two-month period, contributed to the cp2k/cp2k and spack/spack-packages repositories by integrating OpenPMD output format support into CP2K molecular dynamics workflows and enhancing Spack packaging for optional OpenPMD-api dependencies. Leveraged CMake configuration, Fortran programming, and Python-based package management to update build systems, introduce Fortran modules for OpenPMD data structures, and standardize data emission for high-performance computing environments. The work improved data analysis capabilities for CP2K users and strengthened dependency management within Spack, focusing on robust integration, version constraints, and compatibility with OpenPMD toolchains. No major bugs were fixed during this period, emphasizing feature development.
