Worked on optimizing the DistributorPlan initialization process in the trilinos/Trilinos repository, focusing on improving startup performance and reducing CPU usage. The approach involved reusing an existing temporary plan rather than recreating it, and eliminating a redundant createFromSends call by directly assigning the temporary plan. This change streamlined the initialization workflow, reduced unnecessary computations, and enhanced code maintainability and readability. The work demonstrated strong skills in C++ performance optimization, code refactoring, and object lifecycle management. No major bugs were reported during this period, indicating stable delivery and careful attention to code quality throughout the development process.
