Summary

Completed the CUDA + OpenGL check, Nsight debugging/profiling, and WebGL/WebGPU verification. All screenshots are embedded in the README.

Machine: Personal laptop — NVIDIA GeForce RTX 4070 Laptop GPU (SM 8.9), Windows 10 24H2, CUDA 13.0, Visual Studio 2022, Nsight Systems/Compute 2025.3, NVIDIA driver 561.15.

What’s done

• CUDA GL Check

  • Built with CMake + VS2022 and ran successfully (two-tone blue screen).
  • Name set in title bar (“Cindy Wei …”).
  • Screenshot added to images/ and embedded in README.

• Nsight Debugging (VS)

  • Hit breakpoint in kernel.cu at the bounds check.
  • Captured Autos and Warp Info windows.
  • Screenshot saved and embedded.

• Nsight Systems

  • Captured a profiling run of the app.
  • Analysis Summary and Timeline screenshots added.

• Nsight Compute

  • Generated a report for createVersionVisualization(...).
  • Included Summary and Details screenshots (and the .ncu-rep file).
  • Notes: initial attempts with kernel replay threw UnknownError; switched to Application mode and captured a small tile successfully.

• WebGL

  • Hardware acceleration ON in Chrome.
  • Screenshot from webglreport.com / chrome://gpu showing WebGL works.

• WebGPU

  • Verified on https://webgpureport.org.
  • Screenshot shows adapter info (Lovelace) and API available/successful across worker types.

CMake / Build Notes

• No changes to CMakeLists.txt beyond the provided configuration (no custom flags/files added).

Feedback

• Nsight Compute: Kernel-replay on an interactive OpenGL app can be finicky; Application mode worked reliably and is enough for this project’s screenshots.
• Instructions were clear!
