During July 2025, the developer contributed to the ZJUSCT/HPC101 repository by enhancing debugging and observability for convolution validation in C++ with CUDA. They implemented a feature that improves error reporting by identifying the precise indices—specifically n, output_h, output_w, and k—where mismatches occur in convolution output validation. This targeted diagnostic approach enables developers to quickly locate and address issues in numerical kernels, reducing the time spent on debugging. Although no major bugs were fixed during this period, the work demonstrated depth in debugging practices and provided a more reliable foundation for future development and maintenance of HPC101’s validation routines.
