During July 2025, Amlng worked on the dealii/dealii repository, focusing on improving memory profiling for PETSc SparseMatrix. By correcting the memory consumption estimation to account for allocated non-zero element sizes and local indices, Amlng enabled more precise tracking and reporting of memory usage, which is essential for large-scale simulations. This work involved a targeted bug fix in C++ and required a strong understanding of memory management and performance optimization. The update not only enhanced the accuracy of resource tracking but also improved PETSc integration, with thorough documentation updates to ensure clarity for future development and capacity planning.
