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
  • 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
.

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 reserverd for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
