Execute Service

In this exercise, you'll learn to execute the build command and view the terrain analysis report.

Examine Debug Settings

1. Go to the text editor and find the script app_service_workload_analyze_terrain_util.ssl.
2. Find the Execute() function.

   ///////////////////////////////////////////////////////////////////////////////
   // function
   ///////////////////////////////////////////////////////////////////////////////
   
   function bool Execute( CommandPresentationModuleInfo commandInfo )
   {
      auto Str a_oName;
      GetName( a_oName );
   
      //////////////////////////////////////////////////
      // Initialize source data and messages.
      //////////////////////////////////////////////////
   
      auto StrList a_slMessages;
      LibAppServiceBuild.GenerateServiceHeader(
         a_oName.Value, a_slMessages );
   
      auto FilePath a_oElevationDataPath = new FilePath(
         Application.GetApplicationDocumentsPath() );
      a_oElevationDataPath.AppendPath( "Library" );
      a_oElevationDataPath.AppendPath( "Textures" );
      a_oElevationDataPath.AppendPath( "Elevation" );
      a_oElevationDataPath.AppendPathWithFile( "USGS_13_n49w122.tif" );
   
      auto FileNode a_oData;
      a_oData.Name = a_oElevationDataPath.GetFileName();
      a_oData.FilePath = a_oElevationDataPath.GetPath();
   
      //////////////////////////////////////////////////
      // Declare and initialize build objects.
      //////////////////////////////////////////////////
   
      bool a_bDebug = true;
      int a_nDebugMaxChunksX = 4;
      int a_nDebugMaxChunksY = 4;
   
      ...
   

   Notes that a_bDebug is declared at the bottom of this code sample. At present, a_bDebug is true, a_nDebugMaxChunksX is set to 4, and a_nDebugMaxChunksY is set to 4. This allows us to run the compute workload on a limited set of data if we need to debug, or if we are only interested in a small area in the terrain. The variables a_nDebugMaxChunksX and a_nDebugMaxChunksY are used only when a_bDebug is true. You can use the debug flag in a variety of ways in your own implementations.

   For the first run, we'll leave the service in debug mode.

Execute Partial Workload

1. Return to the running Shader app.
2. Select File » Run Service from the main menu.
3. Double click the entry named Spa.Service.AnalyzeTerrain.

   Service execution starts. Note that this should take around 10-20 seconds, depending on your computing hardware.

   The application creates a report and launches it in the default web browser on your computer.

   
4. Left click one of the cells of the terrain to see the analysis:

   This allows you to see the analysis for each cell.

Examine The Log Message

1. Return to the running Shader application.
2. Examine the output window.

   There is a detailed log message, including timings for each major operation.

3. Find the following line:

   bool a_bDebug = true;

4. Set a_bDebug to false.

   bool a_bDebug = false;

5. Save the script.

Execute Complete Workload

1. Return to the running Shader app.
2. Select File » Run Service from the main menu.
3. Double click the entry named Spa.Service.AnalyzeTerrain.

   Service execution starts. Note that this could take 15-30 minutes to complete, depending on your computing hardware. RAM use could peak at around 10GB, and GPU memory use could peak at around 2GB. The build could take longer if you have less than the recommended CPU or GPU memory.

   After service execution completes, the application creates a report and launches it in the default web browser on your computer. The full report uses very large images (approximately 400MB), so you might have to wait while the web browser loads content from disk.

4. Left click one of the cells of the terrain to see the analysis:

   This allows you to see the analysis for each cell.

Examine The Log Message

1. Return to the running Shader application.
2. Examine the output window.

   There is a detailed log message, including timings for each major operation.
