I am using Dell Precision T3500 workstation with Quadro 2000 Nvidia GPU. I installed Cuda 4.2 tool kit with Nsight 2.2. When I debug cuda code using "Start CUDA Debugging" it connect the local machine then just gives a message

A CUDA context was created on a GPU that is not debuggable. Breakpoints will be disabled. Adapter: Quadro 2000

and exit.

Is there any issue with VS project settings or Cuda configuration.

I also tried CUDA 5.0 without any use.

  • It could be releated to the driver you are using. What's your Nsight build number (check from menu Nsight\Help\About Nsight), and the driver version? That could be helpful to get a solution for your issue. Basically, it would be functional with the recommeneded driver version by that Nsight version. – Xuan Wang Oct 18 '12 at 15:58
  • Nsight 2.2 does not officially support Cuda 5.0. And the driver 306.x features Kepler and Cuda 5.0, but with that Nsight 2.2 does not work as perfect as 301.42 . FYI, there will be a preview release of Nsight in coming weeks with Cuda 5.0 support. – Xuan Wang Oct 19 '12 at 10:48
  • I tied to VS 2010 Premium on a system, right now I'll try to use CUDA 5.5.2 and NSight 3.2.2. – Csaba Toth May 07 '14 at 08:17
  • Yes still facing same problem. I will contact nsight team ans update here. Thank you xuan – Zahid Oct 23 '12 at 01:49
  • Please double check whether the CUDA code is compiled with tk 4.2 but not the Cuda5.0. If problem presists, you can try a sample from the samples in Cuda SDK. If still not working, you can send email to parallelNsight-support@nvidia.com, people will assit you in detail. – Xuan Wang Oct 22 '12 at 02:31
  • I tired installing nsight recomemeded drivers and tool kit. Now i dont get that error but in the same time it dont stop on any of the break points in device code. Any hint? – Zahid Oct 20 '12 at 01:54
  • I am using nsight 2.2.01225 and graphic driver is 306.95 . Nsight 2.2 download page says it works well with drivers 301.27 or newer. I also tried cuda 5 . But still get same message :( – Zahid Oct 19 '12 at 01:51

It's possible that the current driver version and nsight version are not compatible with the PC hardware. The following worked for me:

  1. Download the latest CUDA TOOLKIT (current is 7.5).
  2. Reload the CUDA.
  3. Do not update the driver.
