Worked on the trilinos/Trilinos repository to enhance spatial partitioning capabilities by implementing a configurable Hilbert curve selection feature in the HSFC module. Leveraging C programming and data structures, introduced a CURVE parameter and a table-driven approach that enables users to select among multiple Hilbert curve implementations, as described in Haverkort (2017), to better match workload requirements for large-scale simulations. Subsequently refactored the Hilbert curve lookup table initialization in hsfc_hilbert_const.h to achieve C standard compliance, improving code clarity, maintainability, and cross-compiler portability. Focus remained on algorithm implementation, low-level programming, and code quality throughout the development period.

Apr 1, 2025April 2025 performance summary for trilinos/Trilinos: Delivered a focused code quality improvement refactor for Hilbert curve lookup table initialization to achieve C standard compliance, enhancing portability and maintainability across compilers. The change switches from per-field struct assignments to direct array initialization within hsfc_hilbert_const.h, clarifying intent and reducing risk of non-standard behavior. This work supports ongoing quality and portability goals and strengthens stability for Hilbert-curve-related computations.

Mar 1, 2025March 2025 — Delivered a configurable Hilbert curve selection feature in the HSFC module of Trilinos, enabling CURVE parameter-driven selection among multiple Hilbert curve implementations as described in Haverkort (2017). Implemented a table-driven HSFC approach to tailor spatial partitioning to varying workloads. The work is backed by a focused commit: edab7731034ecb9a1f6aed3b9e7dfb76f27b6c82 ('Implement alternative Hilbert curves from Haverkort (2017)'). This improves partitioning accuracy and scalability for large-scale simulations by enabling workload-specific curve choices. No major bugs fixed this month; focus was on feature delivery and code quality." ,
