Imbalance Diagram Dialog Box

The Imbalance Diagram enables you to compare the performance between a real trace and an ideal trace.
Use the Imbalance Diagram total mode to see the time spent on calculation, interconnect, and imbalance as well as the time distribution between them. The diagram displays the time distribution in different colors.
Use the Imbalance Diagram breakdown mode to see:
  1. how three most time-consuming functions of the application work
  2. how much time they spend on three different kinds of messages
  3. what the proportion between interconnect and imbalance for each kind of messages is
The messages can be:
  1. short, 0-512 bytes
  2. medium, 512-32767 bytes
  3. large, > 32767 bytes
To compare a real trace with an ideal trace, take the following steps:
  1. Go to
    Advanced > Imbalance Diagram
     or press the toolbar button .
  2. In the
    Choose Idealized Trace
     dialog box, choose an idealized trace that you want to analyze. You do not have to choose an idealized trace if it already exists in the working directory.  For example:
    Intel® Trace Analyzer
  3. You can specify the following Imbalance Diagram parameters:
    1. Breakdown message thresholds
    2. BDI files rebuilding
    If you have changed the BDI files manually or the files were partially corrupted, select the
    Rebuild the BDI files
     checkbox.
    The BDI files are the ASCII files and contain all the information needed to create an Imbalance Diagram View. The file name is
    <original trace name>
    .bdi
    . The file format is as follows:
    
<version string> <short message threshold> <medium message threshold>
<Function ID> <Collective ID> <Function Name><Total Function Time>
<Short Messages Time> <Medium Messages Time> <Large Messages Time>
  4. Click
    OK
    .
Do not change the BDI file manually. It may result in incorrect feature functioning. You can import the BDI file into a Microsoft Excel* table.
The
BDI File Building
 dialog box displays the progress of BDI files building. To stop the BDI building process, click
Cancel
.
If you stop the BDI building, the
Imbalance Diagram
 dialog box is not displayed.
In the
Imbalance Diagram
 dialog box, specify whether to display and the mode to display (Total mode or Breakdown mode) the application time. For example, Total Mode:
Intel® Trace Analyzer
Breakdown Mode:
Intel® Trace Analyzer
To change the colors used in the Imbalance Diagram, do the following:
  1. In the
    Imbalance Diagram
     dialog box, click
    Colors.
  2. In the
    Imbalance Diagram Colors
     dialog box, click
    Choose Color
    . The result will look like this:
    Intel® Trace Analyzer
  3. Choose the colors and click
    OK
     to save the changes.  
The new colors are stored in the Intel Trace Analyzer Resource file, so you don't need to change them every time you start the Intel Trace Analyzer. To restore the default colors for all elements, click
Reset all colors
.
