Goodchong

Solomon Zhang contributed to the deepmodeling/abacus-develop repository by modernizing core data structures and enhancing preprocessing reliability over a three-month period. He refactored the Atom Input subsystem, unifying fake atom data structures and replacing raw pointers with C++ STL vectors to improve memory management and maintainability. Solomon also optimized the neighbor search system by removing legacy structures, integrating logic into core modules, and introducing box-based partitioning to accelerate lookups. In addition, he implemented an input stream sanitization filter that removes non-ASCII characters and comments, increasing data integrity. His work demonstrated depth in C++, data validation, and software design.

December 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.
