Choose Problems

During analysis, the Intel Inspector displays problems in the order detected in the Problems pane.

After analysis is complete, the Intel Inspector:

  • Groups problems detected during analysis into problem sets (but still provides visibility into individual problems and problem occurrences).

  • Prioritizes the items in the Problems pane.

  • Offers filtering to help you focus on those items that require your attention. For example, you can temporarily limit the items displayed in the Problems pane by:

About Prioritization

Intel Inspector assigns problems a severity level: Critical (), Error () and Warning (). The severity indicates the seriousness of the defect.

Problem sets inherit the severity of the problems they contain. The Intel Inspector prioritizes problem sets first by severity and then by number of code locations. Problem sets containing more code locations precede those containing fewer.

Think of this prioritized list of items on the Problems pane as a to-do list. Start at the top and work down.

About Filtering by Inclusion

Use the Intel Inspector filtering function to temporarily limit the items in the Problems pane to only those problem sets containing problems that meet specific criteria.

For example, you can filter the list to show only those problem sets containing problems...

  • With Investigated=Not investigated to show only problem sets with a state of New, Not fixed, or Regression (that is, hide the problem sets you have already investigated)

  • Or with State=Not fixed and Severity=Error

  • Or with State=Not fixed and Severity=Error and Type=Data Race

  • Or in a specific file

About Filtering by Exclusion

Use the Intel Inspector filtering function to temporarily set aside occurrences of the same, possibly false positive, items en masse in the Problems pane. For example:

  1. In the Investigated category in the Filters pane on the Summary window, choose Not investigated to display only problems with a state of New, Not fixed, or Regression.

    NOTE:

    If this is the first result of this analysis type, or if you chose the Do not get problem states from another result option on the State Management page of the product Options dialog box during startup, all problems have a state of New.

  2. Click the Sort drop-down list in the Filters pane and choose Sort by Item Count to sort remaining problems by count in descending numerical order.

  3. In the Type category in the Filters pane, choose the problem type with the highest item count to display only those problems in the Problems pane.

  4. Click on any problem in the Problems pane, then press Ctrl+A to select all problems.

  5. Right-click any of the selected problems to display a context menu, then choose Change State > Not a Problem to change the state of all selected problems.

  6. In the Type category, click the All button to deselect problem criteria.

  7. Repeat steps 3 - 6 for each problem type with many occurrences.

  8. Start working the remaining problems.

Be aware that when you temporarily set aside problems en masse, you may inadvertently set aside a problem of interest. For example, if you are not responsible for problems in source file A and you:

  1. Use the filtering function to select all problems in source file A.

  2. Set the state for all problems in source file A to Not a problem.

Some of these problems may touch more than one source file. When you filter on a source file, you filter on all problems intersecting that source file. The fact that a problem has some intersection with a file for which you are not responsible does not mean the problem does not concern you.

However if you are responsible for source files A, B, and C, you can filter first to source file A, then to source file B, then to source file C. You may see some problems more than once, but you will ultimately investigate all problems in files for which you are responsible.

About Filtering by a Set of Source Files

Use the Intel Inspector filtering function to temporarily limit the items in the Problems pane to those from a set of source files.
