I am having trouble using the NSight Visual Studio debugging tool with my Titan Z.
I am following the tutorial in the NSight 4.7 User Guide. After having set the proper breakpoints in the kernel, I start CUDA Debugging via the Nsight menu in VS2013 Community.
My screen goes black for about 3 seconds and then comes back. (For what it’s worth, I have tried cudaSetDevice(1) to force the second GPU on the Titan Z to do the work and leave the first for the display, but it made no difference)
The command window output:
VS2013 opened up a new tab titled “Source Not Available”, saying “Code not running - The current thread is not currently running code or the call stack could not be obtained.”
There are no local or auto variables. Continuing to the next breakpoint results in termination of the debug process.
However, the NSight monitor showed an active connection while debugging.
Here is NSight output:
Could someone point me in the right direction? I am unsure of what to do about this problem.
PS: I am using the latest 353.30 driver, CUDA Toolkit 7.5 and NSight 4.7.
