ppwprof outputs most of the same performance data shown by the PPW graphical interface ppw(1), except in text format. The command works by querying each visualization in the graphical interface for a text version, then displaying that text version if one is available.
By default, the data displayed comes from a text version of the profile table visualization. In this mode, the output is similar to what is available from the gprof(1) command. However, by using the --all option, you can also view text versions of the rest of the analyses and visualizations that are normally shown in the PPW GUI.
In short, the ppwprof command generates a text report of performance data information instead of a graphical report like ppw(1).
To invoke ppwprof, use the following syntax:
ppwprof [-s|-l|-p|...] filename.par
ppwprof accepts the following options:
Note that this command requires a Java installation to work properly. If you do not have a Java installation available, please install the GUI on your workstation, or see the PPW manual section entitled `Installing PPW' for more options.
For an alternative to ppwprof(1) that does not require a working Java installation, you may use the ppwprof.pl(1) command.
If you did not configure PPW to use a Java installation at build time, or would like to override which version of Java PPW uses to start the GUI, you may set the JAVA_CMD environment variable to the full path of a Java interpreter.
