Arthur Perais worked on the gem5/gem5 repository, focusing on enhancing simulation determinism by redesigning the simulator’s random number generation system. He introduced per-component RNG isolation, replacing the previous global RNG with dedicated instances for each component, which allowed independent seeding and eliminated cross-contamination of randomness sources. This refactor, implemented in C++ and leveraging his expertise in software architecture and system design, addressed non-deterministic and flaky simulation behavior, thereby improving the reliability of benchmarking and CI validation. Arthur also documented the new RNG module boundaries, laying the foundation for future deterministic strategies and clearer maintenance within the gem5 codebase.
