Worked on the deepmodeling/abacus-develop repository, delivering four features over four months focused on modernizing core data structures, optimizing memory management, and improving input/output reliability. Applied C++ and CMake to refactor the Atom Input subsystem, replacing raw pointers with STL containers for better memory locality and maintainability. Enhanced the neighbor search system by simplifying legacy data structures and introducing box-based partitioning to accelerate lookups. Developed an input sanitization filter to improve data integrity during preprocessing, and modularized the sparse matrix writer interface to support robust testing and compatibility. Emphasized modular programming, data validation, and software testing throughout each project phase.

Jun 1, 2026June 2026 summary for deepmodeling/abacus-develop: Refactor of the Sparse Matrix Writer Interface to improve modularity and maintainability, coupled with Phase 0 compatibility tests for write_HS_R. Fixed critical IO issues to enhance reliability of sparse matrix I/O, including sparse binary header handling and explicit dimension propagation, across MPI and non-MPI paths. Expanded test coverage, added phase-ready build/test automation, and aligned documentation with the refactor plan for Phase 1 progress.

Dec 1, 2024December 2024: Neighbor Search Optimization via Data-Structure Simplification and Box-Partitioning in deepmodeling/abacus-develop. Delivered a performance and maintainability-focused architectural enhancement to the neighbor search subsystem by removing legacy data structures (atomlink/sltk_adjacent_set and atom_input) and integrating functionality into core modules (sltk_atom, sltk_grid, sltk_grid_driver). Introduced box-based partitioning of atoms to speed up neighbor lookups, improve locality, and enable faster, more scalable development and testing. The changes preserve algorithm parity while reducing complexity and maintenance overhead, establishing a foundation for larger-scale simulations.
