Remote GPU Debugging in Visual Studio 11

Remote GPU Debugging in Visual Studio 11

  • Comments 8

Hi my name is Paul Maybee and I am the architect on the Parallel and GPU debugger team, working closely with the C++ AMP team.

We covered previously how to debug C++ AMP code locally, so please read our post on “Start GPU Debugging in Visual Studio 11”. I’ll pick up from step 6 for those of you not wanting to run Windows 8 Consumer Preview on your main development machine.

This post contains the steps necessary to debug a C++ AMP program on a remote host running Windows 8 from a local machine on which you have installed Visual Studio 2012 RC.

For the purpose of these instructions I will make the following assumptions:

  1. The remote machine is named WIN8REMOTE.
  2. The local machine is running a 64 bit operating system.
  3. The location \\WIN8REMOTE\C$\temp is writable from the local machine. 
  4. Visual Studio is installed at “c:\Program Files (x86)\Microsoft Visual Studio 11.0”
  5. The application to be debugged is HelloWorld_AMP.exe found in “%USERPROFILE%\documents\visual studio 11\projects\HelloWorld_AMP\Debug”, built for Win32.  

If these assumptions don’t exactly match your setup then make corresponding changes to the instructions below.

Step 1: One time setup of WIN8REMOTE for remote debugging

  • Install the Windows SDK on WIN8REMOTE.
  • Copy the contents of “c:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Remote Debugger\x86\” to \\WIN8REMOTE\c$\temp\debugger.
  • Log on to WIN8REMOTE and run c:\temp\debugger\msvsmon.exe. When the firewall dialog box comes up allow it to “Configure remote debugging”. 

     Step 2: Configure your project properties for remote debugging

  • Select Project->Properties to open the properties dialog and then Configuration Properties ->Debugging as per screenshot that follows
  • Set “Debugger to launch” to “Remote Windows Debugger”
  • Set “Remote Command” to “c:\temp\HelloWorld_AMP\HelloWorld_AMP.exe” 
  • Set “Working Directory” to “c:\temp\HelloWorld_AMP\”
  • Set “Deployment Directory” to “c:\temp\HelloWorld_AMP\”
  • Set “Remote Server Name” to “WIN8REMOTE”
  • Set “Debugger Type” to “GPU Only”

Step 3: Start debugging

  • Set a breakpoint on line 11 (“av[idx] += 1;”).
  • Press F5 and enjoy

That’s all! If you have any questions, please feel free to ask in the comments section below.
