This section provides a reference guide to the features of the PGPROF performance profiler.
For information about how to invoke PGPROF, refer to Profiler Invocation and Initialization.
For information about using the PGPROF text-based command-line interface, refer to Compiler

For information about how to choose a profiling method, build your program, and execute it to

7.1. PGPROF User Interface Overview
On startup, PGPROF attempts to load the profile datafile specified on the command line or
the default, pgprof.out. If no file is found, a file chooser dialog box is displayed. Choose a
profile datafile from the list or select Cancel.
When a profile datafile is opened, PGPROF populates the user interface, as illustrated and
labeled in Figure 16.
Menu Bar
Contains these menus: File, Edit, View, Sort, and Help.
Toolbar
Provides navigation shortcuts and controls for frequently performed operations.
Statistics Table
Displays profile summary information for each profile entry. Information can be displayed at
up to three levels - routine, line, or assembly - depending on the type of profile data collected,
how the program was built, and whether the PGPROF source file search path has been set to
include the program source directories. The initial view is the routine level view.
Focus Panel
Consists of tabbed panes labeled Parallelism, Histogram, Compiler Feedback, System
Configuration, and Accelerator Performance.
Information Bar
Displays the profile summary information such as the name of the executable, the time and
date of the profile run, execution time, number of processes, if more than one, and the datafile
name.
