Dependencies Analysis Purpose and Usage

View any predicted data sharing problems and informational remark messages.

Dependencies Analysis Prerequisites

To prepare to run a Dependencies analysis:

  1. Do one of the following to open the Analysis Target tab in the Project Properties dialog box:

    • In the Intel Advisor GUI, choose Project > Project Properties…

    • In the Visual Studio IDE, choose Project > Intel Advisor 201n Project Properties….

  2. Choose the Dependencies Analysis type, then specify the same application as in the Survey Hotspots Analysis type, but a smaller input data set if possible. Select Track stack variables to detect all possible dependencies.

  3. Generate a Survey Report.

  4. Mark one or more un-vectorized loops for deeper analysis by enabling the corresponding checkboxes in the Survey Report.

Tip

  • If possible, use the Inherit settings from Survey Hotspots Analysis Type checkbox.

  • The Dependencies Analysis type consumes more resources than the Survey Hotspots Analysis type. If analysis takes too long, consider decreasing the workload.

  • Setting search directories in the Binary/Symbol Search tab and Source Search tabs is optional for the Vectorization Advisor.

  • Marking loops for deeper analysis using the checkbox is a Vectorization Advisor-specific alternative to adding annotations in target application source code.

  • Dependencies analysis is time intensive. The fewer loops you mark for deeper analysis, the less time it takes to collect the data.

  • Choose the optimal compiler settings. The most up-to-date settings are in Getting Started with Intel® Advisor.

Run a Dependencies Analysis

To run a Dependencies analysis, do one of the following:

While analysis is running, you can do the following under the Check Dependencies step in the Workflow tab

Tip

See Getting Started with Intel® Advisor for corresponding command line interface commands.

There are also controls and annotations available to minimize data collection, result size, and execution time. Check See Also.

Dependencies Report Regions and Purpose

In the Dependencies Report tab at the bottom of the Refinement Report:

Associated Dependencies Source window, from top left to bottom right:

Using Dependencies Data

Use the Dependencies Report to view each reported problem and its associated code locations. Use the Dependencies Source window to view the focus and related source code regions to help you understand the cause of the reported problem.

To learn about a reported problem, right-click its name in the Dependencies Report, Problems and Messages pane and select What Should I Do Next?. This displays the help topic for that problem type.
