Quantify collects a complete, accurate set of performance data for your program and its components, including threads, and helps you find exactly where your program spends most of its time. To profile a program's performance:
Instrument and run a program with Quantify to collect performance data.
Analyze the performance data.
Run the program again and compare runs to find performance changes.
Notes:
If Quantify has been installed on your system as a component of Rational PurifyPlus, the Rational directory contains the files purifyplus_setup.csh and purifyplus_setup.sh. To license Quantify for your use, you must source the file that is appropriate to your shell.
You can use Quantify in automated testing.
