Worked on enhancing the reliability and stability of the OpenXiangShan/GEM5 simulation platform by addressing critical issues in parallel checkpoint discovery and multi-threaded cache behavior. Applied expertise in C++, cache coherency, and shell scripting to correct directory boundary matching in checkpoint file identification, ensuring accurate task-specific results during parallel simulations. Improved the SMT LL/SC cache block mechanism by refining lock matching and updating load lock handling, which reduced the risk of livelock in multi-threaded environments. These targeted bug fixes contributed to more robust and correct simulation runs, streamlining debugging and supporting long-running, parallel workloads in complex computer architecture research.
