I would like to start a remote debugging session from my development pc on our soon-to-be production server. On the server I start NSight using the remote desktop, and then I try to Start CUDA Debugging on my local machine (given the server as target before). The result is, that the debug session disconnects saying "The remote system is logged in through remote desktop. WDDM adapters will not be debuggable".
Is this intended behaviour, a bug, wrong configuration? And if there is no solution involveing remote desktop, how could I start the NSight monitor, so that I can start a debugging session?
On the target server I have two Tesla K10 and a Quadro FX (for Display). All Tesla devices (which are actually four), show TCC turned on.
I am using NSight 3.0, CUDA 5.0 and Visual Studio 2008 (the latter two only on the development workstation).
One last thing: Copying the application to the server and executing through remote desktop works fine.
The message you refer to is a warning to let users know that Nsight has detected that you have a RDP session running on the target side and that it won't be able to do Nsight debugging on any WDDM cards in it, if there is one (or more) - which looks like you do, with that Quadro FX that you mentioned). This message is a Warning, and it should continue to let you run or debug the application under Nsight and debug the application assuming GPU code runs on the TCC devices. Are you sure the application ran successfully on the target machine? Can you double check that you have set a GPU breakpoint and see if you hit those breakpoint(s)? Are there any other messages shown? - you can check the VS Output window.
Which driver version are you using?
Can you try running (double clicking) the application on the server but from the directory that Nsight synced the application to? It should be under %appdata\NVIDIA Corporation\Nsight\Monitor\Mirror\<hostdev_machine_name>\<path_to_the_sync_app>
I know you mentioned you tried copying it, but I'd like to see if everything that Nsight sync is what's required by the application and that maybe there's not something missing that you need to specify to sync (more info on syncing is here: http://http.developer.nvidia.com/NsightVisualStudio/3.0/Documentation/UserGuide/HTML/Content/Synchronization.htm)
Thank you
