The main window is split in the middle. On the left-hand side it
displays a list of the instrumented sections. They are labled with the
second argument of the command
hpmStart. The column ``Count'' shows how often
the instrumented section was entered in the run under
investigation. This is followed by two timings. Both are derived from
the wall-clock time. ``IncSec'' gives the time spent in this section.
In the column ExcSec, the time spent in instrumented regions, which
are nested inside the region under investigation, has been subtracted.
The right-hand side of the main window displays the source code.
The HPMVIZ main window
By clicking with the left mouse button on one of the sections in the
left-hand side, the relevant code section will be highlighted in the
right-hand window. Clicking on an instrumented section with the right
mouse button will open a ``metrics'' window for this section.
