Concise monthly summary for 2025-08 highlighting key deliverables, fixes, impact, and skills demonstrated for ZJUSCT/HPC101. Summary of key outcomes: - NaN-aware correctness verification for the Winograd algorithm and its CPU variant, preventing NaN outputs from being treated as valid results and increasing reliability of numerical checks. - Cross-path consistency improvements between the Winograd algorithm and the Winograd CPU version, reducing divergence in verification paths. - Clear traceability of changes with commit-level documentation for major fixes. Impact: - Enhanced reliability of numeric verification in HPC workloads, reducing risk of silent failures and improving confidence in results used for performance optimization and validation. - Faster issue resolution due to explicit NaN handling and consistent behavior across execution paths. Technologies/skills demonstrated: - Debugging, numerical verification, NaN handling, cross-component validation (GPU/CPU paths), and commit-driven traceability. Key achievements: - Implemented NaN-aware correctness check for Winograd verification, preventing NaN outputs from passing verification (applied to both Winograd algorithm and Winograd CPU version). - Ensured cross-path consistency between GPU algorithm and CPU variant, reducing divergence in outcomes. - Documented fixes with explicit commits for traceability.
