CPU Task Analysis in the Intel® GPA Platform Analyzer
The Intel® GPA Platform Analyzer enables you to visualize the execution profile of the various tasks in your code over time.
Instrumenting Your Application for Analysis in the Intel GPA Platform Analyzer
The Intel® GPA Platform Analyzer is an instrumentation-based tool. This means that you must instrument your application with ITT (Intel® Tracing Technology) API calls to capture trace data that you can analyze. For Microsoft DirectX* applications, Intel GPA already provides a basic level of ITT instrumentation, which you can augment by inserting ITT API calls into your code.
For detailed information regarding the ITT API, refer to the Intel® GPA SDK Reference.
