Parallel NSight Cuda Debugging problem

    Posts: 2
    Hello I have CUDA 4.1 RC2 installed with parallel Nsight 2.1 RC2 and VS 2010.

    I followed the tutorial for debugging in the user guide parallel nsight program provided but when i set breakpoints on the correct place the debugging does not stop at the break points.

    VS just shows:
    Parallel Nsight Debug
    A CUDA context was created on a GPU that is not currently debuggable. Breakpoints will be disabled. Adapter: GeForce 8800 GTS

    Host:
    Vista 32bit, VS2010 Ultimate
    Mobile Intel 4 GMA & GeForce 9300M GS (hybrid)

    Target:
    Vista 32bit, VS2010 Ultimate
    8800 GTS
    286.16

    What am I doing wrong here?

    Thanks for your help!

    Greetings

    Hi Raul,

    How much VRAM does your 8800 GTS have?

    Parallel Nsight only supports the version with 512MB of ram.

    Thanks!

    Just to make sure: did you activate the "Generate GPU Debug Information" switch (-G0) in the project settings? This switch is not automatically set after you install a new toolkit, even if you select the debug solution configuration.
    This cost me almost 2 days once :)

    Hello,

    the 8800 GTS has 320 VRAM. I'll try another card to sse if it's really the card, I hope that will solve the problem.

    @franzdaubner, the "Generate GPU Debug Information" is set to (-G0) by default after a clean install. :(

    Thank you for the answers!

    Hi Raul,

    Unfortunately the 8800 GTS with 320MB of VRAM is unsupported. This is due to a major architectural change that occurred during the run of that series of cards. I apologize for the inconvenience.

    Thanks!
