Selecting the GPU Sampling Interval

Intel® GPA supports a wide variety of metrics. The metrics available for display might differ depending on your specific graphics device.
NOTE
The HUD is not available in the stream mode.
To configure the metrics that are collected, do the following:
  1. Start the Graphics Monitor.
  2. On the
    Graphics Monitor Launcher
    screen
    , click the button.
  3. Go to the
    Metrics
    tab and configure the available metrics options:
  • Select the
    GPU Sampling Interval
  • Enable/disable GPU metrics collection by the target application
  • Enable/disable Null Hardware override support
  • Customize
    the
    System Analyzer HUD position
  • Configure the HUD metrics:
    • Drag and drop a desired metric to add it to the list of metrics to be displayed in the System Analyzer HUD from the list of available metrics to the Active HUD Metrics list. You can select up to four metrics that are overlaid on your running application.
    • To change the metrics that are displayed, you can remove a metric from the Active HUD Metrics list by dragging and dropping this metric back to the list of available HUD metrics; or reorder the Active HUD Metrics list by dragging and dropping a desired metric over another active metric; or hover over the metric to be removed, and then click the
      X
      button.
  • Select the active metric set by using the
    Active Metric Set
    drop-down menu in the
    GPU
    section of the metric tree
In
Frame
mode, metrics are sampled every frame and are only collected from the target application. When you select any other value, System-Wide Time-Based metric collection is enabled. In this mode, Graphics Monitor collects metrics from the entire system with the selected frequency. This may interfere with profiling if other GPU-intensive applications are running. It is recommended to close other GPU-intensive applications when using any sampling interval other than
Frame
.

Changing a D3D Device for the Instrumented Process

While your graphics application works with multiple D3D devices, you can change which D3D device for the instrumented process being used to collect metrics and show the System Analyzer Heads-up Display.
  1. Launch your application that works with multiple D3D devices, as described in Launching an Application.
  2. Enable the HUD Display Mode by using the
    Ctrl+F1
    keyboard shortcut.
  3. Change D3D devices by using the
    Ctrl+F5
    keyboard shortcut.
For example, you can change a D3D device of the instrumented process for Mozilla* Firefox*, if the System Analyzer HUD is displayed on the title bar instead of the tab of interest.

Product and Performance Information

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.
