PROFILE
Simon Homes
Over two months, Sebastian Homes enhanced the ls1-mardyn repository by restoring and improving input parsing for ASCII phase-space headers, enabling accurate extraction of simulation parameters such as time, temperature, and box dimensions. He applied C++ and CMake to refactor legacy code, streamline the build system, and remove deprecated components, reducing maintenance overhead and improving reliability. Sebastian also introduced mass-aware velocity initialization and temperature-consistent momentum handling for particle dynamics, addressing physical fidelity in molecular dynamics simulations. His work included comprehensive code cleanup, bug fixes, and validation improvements, resulting in a more maintainable codebase and faster, more accurate simulation workflows.

Dec 1, 2024December 2024 – ls1-mardyn: Stabilized core input pathways and streamlined the codebase. Delivered ASCIIReader Input Method Restoration enabling parsing of ASCII phase-space headers to read time, temperature, box dimensions, and component properties. Completed extensive codebase cleanup and deprecation of legacy/unused components (MPI IO readers/writers, validation tooling, standalone generators, GUI generators, and various obsolete scripts/tools), plus build-check reorganization. These changes reduce maintenance burden, minimize risk from dead code, and improve reliability and onboarding. Demonstrated technologies: C/C++ parsing logic, header-driven data extraction, build system reorganization, refactoring, and code hygiene. Business value: more reliable input handling, faster feature delivery in 2025, lower maintenance costs, and easier future enhancements.
