Worked on the NVIDIA/cuda-samples repository to address GPU runtime constraints affecting kernel launch reliability and debug-mode stability. Focused on debugging and performance tuning using CUDA and C++, the developer increased the pending kernel launch limit in cdpAdvancedQuicksort.cu to support larger workloads and prevent launch failures. Additionally, they enforced a per-thread register usage limit in debug mode within the conjugateGradientMultiBlockCG sample by updating CMakeLists.txt, aligning sample configurations with hardware constraints. These targeted changes improved the maintainability and future-proofing of the codebase, ensuring more robust kernel launches and stable debugging behavior across CUDA sample applications without introducing new features.
