问题
I'm trying to debug a cuda application using Nsight with Visual Studio 2008, so I opened the Attach to Process dialog. I set the Transport to be Nsight GPU Debugger. I set the Qualifier to the name of my machine (MONAD in this case). I see a list of processes in the Available Processes widget, but they are all greyed out, and if I click on my application, it remains greyed out and I cannot click the attach button.
When I built the application I made sure to use the -G0 flag when compiling my .cu files with nvcc

Please make sure you have set the monitor settings and the environment variables as described in the Nsight Visual Studio Edition 3.0 chapter Attach Debugging to a Running CUDA Process
Let me know if that helps. Thanks
