Platform Analysis

If your application is CPU-bound, you can capture trace data during the application run to perform in-depth platform analysis with respect to the CPU and GPU activity distribution. Intel® GPA collects real-time trace data during the application run and provides information on the code execution on the various CPU and GPU cores in your system, so that you can analyze some CPU-based workloads together with GPU-based workloads within a unified time domain. With Intel® GPA, you can:
  • Explore GPU usage and analyze a software queue for GPU engines at each moment of time
  • Analyze GPU usage per DMA packet on a software queue
  • Analyze API calls (draw calls, buffer locks, resource updates, presents)
  • Correlate CPU and GPU activity and identify whether your application is GPU or CPU bound
  • Explore your application performance for user tasks created with the Intel® ITT API
  • Identify GPU and CPU application frame rate and how it depends on vertical synchronization
  • Explore the performance of your application over time per selected GPU metrics
The typical workflow is as follows:
1.
Configure Platform analysis
  1. Launch Graphics Monitor from the Windows* Start menu.
  2. From the Graphics Monitor context menu, open the r screen and click the button.
  3. In the
    Trace
    tab, turn on the
    Tracing
    toggle button to enable trace data collection.
  4. Optionally, configure other analysis options, such as a set of default GPU/CPU metrics to monitor for your application.
    Note
  5. From the
    Graphics Monitor Launcher
    screen navigate to your target application.
2.
Run Platform analysis
In the
Graphics Monitor Launcher
screen, click the
Start
button to launch the application and start tracing.
To capture the trace data to a file, choose one of the following tools:
  • System Analyzer HUD
    To capture the trace data to a file, press
    Ctrl+Shift+T
    . This is a default key combination that can be changed in the
    Options
    dialog box
    : Shortcuts
    tab.
  • System Analyzer
    To capture the trace data, do the following:
    • From the Graphics Monitor context menu, launch the System Analyzer.
    • Connect the System Analyzer to your running application.
    • From the
      System Analyzer
      window, modify the list of metrics to monitor, if required.
    • Click the
      Capture Trace
      button to create a trace file.
      Note
      By default, trace duration is five seconds. Tracing settings can be changed in the Trace tab of the Graphics Monitor Options screen.
3.
View collected data
  1. From the Graphics Monitor context menu, launch
    Graphics Trace Analyzer
    .
  2. In the window, select and open the captured trace file.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
