PROFILE
Anna
Over three months, contributed to the IPPL-framework/ippl repository by developing new numerical features and strengthening distributed computing infrastructure. Built Lp norm calculations for vector classes and introduced both standard and nonstandard FDTD solvers with absorbing boundary conditions, expanding the library’s scientific computing capabilities. Enhanced build and test infrastructure using CMake and Python, enabling reproducible convergence studies. Refactored domain decomposition logic and initialization routines for multi-rank environments, improving robustness and error handling in parallel simulations. Added SubFieldLayout support for sub-regions, implemented runtime checks, and improved documentation, focusing on maintainability and correctness. Work emphasized C++, MPI, and high-performance computing techniques.

Jun 1, 2025June 2025 highlights: Delivered two major feature implementations in IPPL with accompanying test coverage and build infrastructure enhancements. Lp norm calculation for the Vector class was added with API refinements to ensure const-correct p-norm usage. Standard and NonStandard FDTD solvers were introduced with second-order absorbing boundary conditions for faces, edges, and corners, along with a base class architecture, AbsorbingBC integration, and supporting tests, docs, and build/test infrastructure. The month also included test infrastructure improvements, documentation updates, and Python-script-based convergence plotting. No major bug fixes were closed this month, but PR hygiene and issue-addressing activities improved code quality and review throughput. Business value: expands numerical capabilities (vector norms, EM solvers) for more accurate analyses, enables reproducible convergence studies, and strengthens build/test reliability for faster iteration cycles.
