print the version number and exit.
print usage information and exit.
verify if the hardware and software environment is supported.
enable (on) or disable (off) verbose mode; the default is "off".


The driver supports various commands. These are listed below.

It is also possible to invoke the lower level commands directly, but since these are subject to change, in particular the options, we recommend to use the driver.

The man pages for the commands below can be viewed using the command name with "gprofng" replaced by "gp" and the spaces replaced by a dash ("-"). For example the man page name for "gprofng collect app" is "gp-collect-app".

The following combination of commands and keywords are supported:

Collect performance data

collect application performance data.

Display the performance results

display the performance data in ASCII format.
generate an HTML file from one or more experiments.
display source or disassembly with compiler annotations.
