Custom Tracks and Track Groups Overview
The Intel® GPA Trace Collector automatically creates Track Groups and Tracks associated with the processes and threads in your application. By default, tasks and markers are thus automatically associated with the correct track and track group for the thread and process in which they occur. In some cases you may need to define logical tracks other than the default thread-specific tracks for specific tasks, and to group such tracks into custom groups other than the default process-specific track groups. The API functions described in this section enable you to do this.
