OptiX debugging and profiling tools

We are excited to announce that Nsight Compute and cuda-gdb now have support for debugging and profiling OptiX applications! These tools will work for both OptiX 6 and OptiX 7 projects.

The following tools now support OptiX programs:

  • Nsight Visual Studio Edition’s Next-Gen CUDA Debugger
  • Nsight Visual Studio Edition’s Nsight Compute Profiler
  • Nsight Compute Profiler
  • cuda-gdb debugger

The latest version of Nsight Compute with OptiX support is available as part of the CUDA Toolkit, or directly here: https://developer.nvidia.com/nsight-compute-2019_4

cuda-gdb is part of the latest CUDA Toolkit: https://developer.nvidia.com/cuda-gdb

Using these tools with OptiX requires a 435 driver or newer. https://www.nvidia.com/Download/index.aspx (Note that right now, Quadro 435 drivers are found under “Beta” for Linux and “New Feature” for Windows.)

We will soon be posting a video demonstration of profiling an OptiX application, so stay tuned.

Note If you have questions, please feel free to start a new thread. I’m locking this thread only to save a spot for updates and announcements, not to limit questions. There is also a forum dedicated to Nsight Compute issues here: https://devtalk.nvidia.com/default/board/327/nsight-compute-
