PROFILE
Simon Homes
Over two months, contributed to the ls1-mardyn repository by restoring ASCIIReader input parsing and implementing mass-aware velocity initialization for molecular dynamics simulations. Focused on C++ and CMake, the work included refactoring legacy code, removing deprecated components, and reorganizing build checks to streamline maintenance and improve reliability. Enhanced simulation fidelity by introducing logic that accounts for particle mass in velocity assignment and ensures temperature consistency after momentum adjustments. Addressed a compilation issue by correcting missing standard library includes. These efforts reduced technical debt, improved code organization, and enabled more accurate simulations, supporting faster feature delivery and easier onboarding for future development.

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.
