In the main Puma window, make sure that a data file is highlighted and then click on
Analyze Call Tree (Textual). The Analyze Call Tree (Textual) window appears, as shown in Title not available.
Like the Call Tree Analysis (Graphical) window, this window shows how the
performance data is distributed among the libraries and procedures in the
program. It gives you a variety of choices for displaying the resource
metrics that were summarized in the Pan/Zoom window.
If you invoke the Call Tree window from the main Puma window, as this tutorial has
done, it displays data for the entire program. You can also invoke it from
the Pan/Zoom window to see the data for an "exploded view," or subset of the data
samples.
Explore the pulldown menus on the Call Tree window to see the display
choices you can make. For example:
Report lets you specify whether the next metric you choose should
begin a new display or appear as a new column in the current display.
Click on Add....

| Replace Report |
| Add Column to report |
Metric lets you choose the resource metrics to display. The table
can display more than one metric at a time. Click on User Cycles to see the display change (Title not available).

| Files Open |
| Characters of I/O |
| All Metrics |
Granularity lets you choose the degree of aggregation of the data and whether to display source line numbers. Choose Help:Granularity for explanation of the terms used in the Granularity menu.
Table 2-5 The Granularity Pulldown Menu
| In Routine |
| In Routine/Show Source Lines |
| In or Under Routine |
| In or Under Routine/Show Source Lines |
| In Source Line |
| In or Under Source Line |
| In Library |
| In or Under Library |
Both the Metric and Granularity menus are tear-off menus. When
you click on the dashed line at the top of the menu, the menu is displayed
in its own window. The menu persists in that window so that you can
invoke commands without having to redisplay it. You can also move the
menu to a convenient place in your workspace.
At the bottom of the Call Tree window, there are more features you
can use to control the display.
Sort lets you arrange the bars
alphabetically by
routine name, which
is useful for finding a particular routine
by the frequency of the
selected metric, which is useful for showing where resource use is
concentrated
hierarchically, which is useful for showing the dynamic call structure of the program
Hierarchical Sort Options gives you further display choices if you have chosen to sort the routines hierarchically. Choose
Help:Sort/Filter for an explanation of these items.
You can save the current display in two ways: by clicking on the Copy Table to
New Window button or by choosing the File:Save Table to File pulldown menu entry.
In summary, the differences between analyzing the call tree graphically
versus textually are:
The graphical display is more immediately intuitive.
The textual display can show more than one metric at a time.
The graphical display provides source clickback capability.
The textual display provides the hierarchical sort option.
Click on File:Close to close the Call Tree window and return to the main Puma window.
