  • Survey Analysis Types
    • Survey Hotspots Analysis
    • Trip Counts and FLOP analysis
    • Suitability Analysis
  • Refinement Analysis Types
    • Memory Access Patterns Analysis
    • Dependencies Analysis

2

Analysis Properties

Set project properties for the analysis type selected in the Analysis Type region.

Analysis Target Tab Controls

The following table covers project properties applicable to all analysis types. To view controls applicable only to a specific analysis type, use the links immediately below:

Use This

To Do This

Target type drop-down

  • Analyze an executable or script (choose Launch Application).

  • Analyze a process (choose Attach to Process).

If you choose Attach to Process, you can either inherit settings from the Survey Hotspots Analysis Type or specify the needed settings.

Inherit settings from Visual Studio project checkbox and field (Visual Studio* IDE only)

Inherit Intel Advisor project properties from the Visual Studio* startup project (enable).

If enabled, the Application, Application parameters, and Working directory fields are pre-filled and cannot be modified.

Application field and Browse... button

Select an analysis target executable or script.

If you specify a script in this field, consider specifying the executable in the Advanced > Child application field (required for Dependencies analysis).

Application parameters field and Modify... button

Specify runtime arguments to use when performing analysis (equivalent to command line arguments).

Use application directory as working directory checkbox

Automatically use the value in the Application directory to pre-fill the Working directory value (enable).

Working directory field and Browse... button

Select the working directory.

User-defined environment variables field and Modify... button

Specify environment variables to use during analysis.

Managed code profiling mode drop-down

  • Automatically detect the type of target executable as Native or Managed, and switch to that mode (choose Auto).

  • Collect data for native code and do not attribute data to managed code (choose Native).

  • Collect data for both native and managed code, and attribute data to managed code as appropriate (choose Mixed). Consider using this option when analyzing a native executable that makes calls to managed code.

  • Collect data for both native and managed code, resolve samples attributed to native code, and attribute data to managed source only (choose Managed). The call stack in the analysis result displays data for managed code only.

Child application field

Analyze a file that is not the starting application. For example: Analyze an executable (identified in this field) called by a script (identified in the Application field).

Invoking these properties could decrease analysis overhead.

Note

For the Dependencies Analysis Type: If you specify a script file in the Application field, you must specify the target executable in the Child application field.

Modules radio buttons, field, and Modify... button

  • Analyze specific modules and disable analysis of all other modules (click the Include only the following module(s) radio button and choose the modules).

  • Disable analysis of specific modules and analyze all other modules (click the Exclude only the following module(s) radio button and choose the modules).

Including/excluding modules could minimize analysis overhead.

Use MPI launcher checkbox

Generate a command line (enable) that appears in the Get command line field based on the following parameters:

  • Select MPI Launcher - Intel or another vendor

  • Number of ranks - Number of instances of the application

  • Profile ranks - All or a range of ranks to profile

Automatically stop collection after (sec) checkbox and field

Stop collection after a specified number of seconds (enable and specify seconds).

Invoking this property could minimize analysis overhead.

To Do This

Automatically resume collection after (sec) checkbox and field

Start running your target application with collection paused, then resume collection after a specified number of seconds (enable and specify seconds).

Invoking this property could decrease analysis overhead.

Tip

The corresponding CLI action option is -resume-after-<integer>, where the integer argument is in milliseconds, not seconds.

Sampling Interval selector

Set the wait time between each analysis collection sample while your target application is running.

Increasing the wait time could decrease analysis overhead.

Collection Data limit, MB selector

Set the amount of collected raw data if exceeding a size threshold could cause issues. Not available for hardware event-based analyses.

Decreasing the limit could decrease analysis overhead.

Stack unwinding mode drop-down list

Set to After collection if:

  • Survey analysis runtime overhead exceeds 1.1x.

  • A large quantity of data is allocated on the stack, which is a common case for Fortran applications or applications with a large number of small, parallel, OpenMP* regions.

Otherwise, set to During Collection.

Stitch stacks checkbox

Restore a logical call tree for Intel® Threading Building Blocks (Intel® TBB) or OpenMP* applications by catching notifications from the runtime and attaching stacks to a point introducing a parallel workload (enable).

Disable if Survey analysis runtime overhead exceeds 1.1x.

Analyze MKL Loops and Functions checkbox

Show Intel® Math Kernel Library (Intel® MKL) loops and functions in Intel Advisor reports (enable).

Enabling could increase analysis overhead.

Note

Analyzing non-executed code paths in binaries that target multiple ISAs (contain multiple code paths) is available only for binaries compiled using the -ax (Linux* OS) / Qax (Windows* OS) option with an Intel compiler.

Enable registry spill/fill analysis checkbox

Calculate the number of consecutive load/store operations in registers and related memory traffic (enable).

Enabling could increase analysis overhead.
