Intel Advisor: Survey Report controls
There are many controls available to help you focus on the data most important to you, including the following:
Click the control to save a read-only result snapshot you can view any time.
Intel Advisor
stores only the most recent analysis result. Visually comparing one or more snapshots to each other or to the most recent analysis result can be an effective way to judge performance improvement progress.
To open a snapshot, choose
Click the various
controls to temporarily limit displayed data based on your criteria.
Click the control to view loops in non-executed code paths for various instruction set architectures (ISAs). Prerequisites:
  • Compile the target application for multiple code paths using the Intel compiler.
  • Enable the
    Analyze loops in not executed code path
    checkbox in
    Project Properties
    Analysis Target
    Survey Hotspots Analysis
This toggle control currently combines two features: The
View Configurator
and the
Smart Mode
  • View Configurator
    - Toggle on the
    Customize View
    control to choose the view layout to display:
    Smart Mode
    , or a customized view layout. To create a customized view layout you can apply to this and other projects:
    1. Click the
      control next to the
      View Layout
      drop-down list to open the
      Configure Columns
      dialog box.
    2. Choose an existing view layout in the
      drop-down list.
    3. Enable/disable columns to show/hide.
      Copy n
      is added to the name of the selected view layout in the
      drop-down list.
    4. Click the
      button and supply an appropriate name for the customized view layout.
    5. Click
      to save the customized view layout.
  • Smart Mode Filter
    - Toggle on the
    Customize View
    control to temporarily limit displayed data to the top potential candidates for optimization based on
    Total CPU Time
    (the time your application spends actively executing a function/loop and its callees). In the
    drop-down list, choose one of the following:
    • The
      of top loops/functions to display
    • The
      Total CPU Time
      the displayed loops/functions must equal or exceed
Click the button to search for specific data.
Click the tab to open various
Intel Advisor
reports or views.
Right-click a column header to:
  • Hide the associated report column.
  • Resume showing all available report columns.
  • Open the
    Configure Columns
    dialog box (see #4 for more information).
Click the toggle to show all available columns in a column set, and resume showing a limited number of preset columns in a column set.
Click the control to:
  • Show options for customizing data in a column or column set.
  • Open the
    Configure Columns
    dialog box (see #4 for more information).
For example, click the control in the
Compute Performance
column set to:
  • Show data for floating-point operations only, for integer operations only, or for the sum of floating-point and integer operations.
  • Determine what is counted as an integer operation in integer calculations:
    • Choose
      Show Pure Compute Integer Operations
      to count only ADD, MUL, IDIV, and SUB operations.
    • Choose
      Show All Operations Processing Integer Data
      to count ADD, ADC, SUB, MUL, IMUL, DIV, IDIV, INC/DEC, shift, and rotate operations.
Click the control to show/hide a chart that helps you
visualize actual performance against hardware-imposed performance ceilings, as well as determine the main limiting factor (memory bandwidth or compute capacity), thereby providing an ideal roadmap of potential optimization steps.
Click a data row in the top of the
Survey Report
to display more data specific to that row in the bottom of the
Survey Report
. Double-click a loop data row to display a
Survey Source
window. To more easily identify data rows of interest:
  • = Vectorized function
  • = Vectorized loop
  • = Scalar function
  • = Scalar loop
Click a checkbox to mark a loop for deeper analysis.

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.
