Using PGPROF
Figure 2 PGPROF Initial View
‣ To zoom in to the line level for a particular routine, double-click the function name.
This action opens a tab that displays profiling data specific to the given function. The tab
label is the function name followed by an x icon. You use the x icon to close the tab when
you no longer want to view that information.
In this tab, PGPROF displays the source code for that routine, together with the performance
data for each line. For example, if you double-click on the function fft, PGPROF displays
a new tab labelled fft that contains the source code for that function, as illustrated in Figure
3.
Because your program is probably optimized, you may notice that performance data is only
shown for a subset of the source lines. For example, a multi-line loop may only have linelevel
data for the first line of the loop.
