PROFILE
Hendrik Roch
Over six months, contributed to the JETSCAPE/JETSCAPE repository by developing and refining simulation features and resolving critical bugs in high energy physics workflows. Focused on improving simulation reliability and reproducibility, this work included enhancing XML-based configuration for modules like FreestreamMilne and IP-Glasma, standardizing build and dependency management with CMake, and modularizing parameter files for maintainability. Addressed issues in hydro data handling and event processing, ensuring accurate physics observables and efficient memory usage. Leveraged C++, XML, and build scripting to streamline integration, clarify documentation, and reduce onboarding friction, resulting in a more stable and configurable simulation environment for end users.

Jul 1, 2025July 2025 monthly summary for JETSCAPE/JETSCAPE focusing on stability and correctness of hydro data handling. Implemented a default safety rule to prevent unintended hydro data storage when output_evolution_every_N_timesteps is not provided, by forcing store_hydro_info_in_memory to 0. This change reduces memory usage and avoids related errors in simulations with implicit or omitted timestep output intervals.

Feb 1, 2025February 2025 was focused on stabilizing and enabling production-grade execution of JETSCAPE/JETSCAPE by consolidating IP-Glasma integration with build-system consistency, tightening pre-equilibrium timing, standardizing critical parameters, and cleaning up repository hygiene. These changes reduce build-time variability, improve physical accuracy in the simulation pipeline, and clarify configuration for end users and future maintainers.
