The Address Space display is divided into two display panes:

• The left display pane contains a legend for interpreting the graphical representation on the right.
• The right display pane shows a graphical representation of the program's address space.

The default display is by page (this is also the display that appears if you click Page from the Unit radio buttons). Each square represents a page in the address space, and the fill pattern indicates whether the page was modified (written to), referenced (read from), or unreferenced (neither) by your program.

If you click Segment from the Unit radio buttons, the right display pane shows an undifferentiated representation of the blocks of memory used by your program.

You can perform the following operations in the Address Space display:

• Getting Detailed Information About a Page or Segment
• Selecting Experiments, Samples, Threads, and LWPs for Analysis

Address-space information is available to the Performance Analyzer only if address-space data was selected when the experiment was generated. Otherwise, the Performance Analyzer reports that address-space is not available.
