During March 2025, William Smith developed the SolverMPGMRES iterative solver for the dealii/dealii repository, expanding the toolkit for large-scale linear systems. He implemented configurable indexing strategies using advanced C++ and numerical linear algebra, refactoring the solver architecture to support flexible Krylov-space construction. Smith also updated SolverFGMRES to leverage the new indexing approach, ensuring consistency across solver implementations. His work included comprehensive documentation that clarified both mathematical foundations and implementation details, reducing onboarding time and maintenance risk. The depth of his contributions lay in modular software design, technical writing, and the integration of numerical methods to improve solver configurability and performance.
