Figure 2-14 Eclipse Open Performance Data View
Using the Peekperf GUI
The peekperf GUI is another user interface for the IBM HPC Toolkit. You use the GUI for
instrumenting your application, running your instrumented application, and obtaining
performance measurements in the following areas:
Hardware performance counter measurements
MPI profiling
OpenMP profiling
Application I/O profiling
The peekperf GUI maps performance measurements to your source code, and allows you to
sort and filter the data. Peekperf is started by issuing the command peekperf. When you
issue the peekperf command, the peekperf GUI main window is displayed. When the main
window opens, you load an application executable, open visualization data files that contain
your performance measurements, and open application source files.
Figure 2-15 on page 139 shows the peekperf data collection window with expanded
application structure after an application executable is loaded.
