Worked on the gem5/gem5 repository to enhance simulation determinism by delivering per-component random number generator (RNG) isolation. Refactored the simulator’s RNG usage in C++ to ensure each component maintained its own dedicated RNG instance, eliminating the previous global RNG sharing that caused non-deterministic and flaky simulation behavior. This approach allowed for independent seeding and reproducible results across simulation runs, supporting more reliable benchmarking and continuous integration validation. Documented the new RNG isolation design and clarified module boundaries, laying the foundation for future deterministic strategies. The work demonstrated skills in code refactoring, software architecture, and system design within simulation environments.
