To End Performance Measurements - HP MC68360 User Manual

Chapter 8: Making Software Performance Measurements
Running Measurements and Creating Reports
Examples To run the performance measurement, enter the following command:
performance_measurement_run 20 <RETURN>
The command above causes 20 traces to occur. The SPMT processes the trace
information after each trace, and the number of the trace being processed is shown
on the status line.

To end performance measurements

• Use the performance_measurement_end command.
The performance_measurement_end command takes the data generated by the
performance_measurement_run command and places it in a file named perf.out
in the current directory. If a file named "perf.out" already exists in the current
directory, it will be overwritten. Therefore, if you wish to save a performance
measurement, you must rename the perf.out file before performing another
measurement.
The performance_measurement_end command does not affect the current
performance measurement data which exists within the emulation system. In other
words, you can add more traces later to the existing performance measurement by
entering another performance_measurement_run command.
Once you have entered the performance_measurement_end command, you can
use the perf32 report generator to look at the data saved in the perf.out file.
Note that the "perf.out" file is a binary file. Do not try to read it with the UNIX
more or cat commands. The perf32 report generator utility (described in the
following section) must be used to read the contents of the "perf.out" file.
Examples
To cause the processed trace information to be dumped to the "perf.out" file:
performance_measurement_end <RETURN>
