Figure 4.30. Pie diagrams in the Load Balance tab
Call Tree
The Load Balance tab offers to display the data in form of pie diagrams (refer
to Figure 4.30, “Pie diagrams in the Load Balance tab”). The button in the top
right corner of the tab allows to switch back and forth between the usual list and
the pie diagrams. This allows to judge the overall load balance pattern (for TSelf)
even among a huge number of processes in a relatively confined space. Above
the pie diagrams are two sliders. The left one controls the minimum radius of the
pies and the right one controls how many pie diagrams appear in a row.
When the Load Balance and Flat Profile tabs do not show enough detail, use
the Call Tree tab to include calling dependencies in your analysis. The Call Tree
tab shows the same information as the Flat Profile and Load Balance, but also
includes the calling hierarchy.
Select a certain entry in the Call Tree to focus on it. The focus remains on this
entry even when the time interval is changed due to scrolling or zooming. It stays
selected and visible when possible. If a corresponding entry is absent for the new
time interval, then its parent is selected. This feature is very useful in large and
deeply nested call trees.

Call Graph
The Call Graph tab shows a small part of the call graph for each process or process
group: a single node (called central function) with its inbound and outbound
edges. Each process entry has three children: the Callers, the central function
and the Callees.
