Scheduling Intensity
This view displays the amount of context switches over time. By default, it shows the whole trace divided into 100 intervals. For each time interval, a bar is drawn for each actor beginning or resuming execution at least once in that interval. The height of the bars represents the number of times that actor has begun or resumed execution in the given interval (i.e., the number of fragments of the actor).
You can control the number of intervals through the Resolution menu. To zoom in on a selection, click and drag to select an interval and use the Zoom or right click menu option.
NOTE: When zooming in the Scheduling Intensity view, the interval length decreases to show a more detailed graph. When zooming in closely, or when the trace is short, the graph may contain empty space corresponding to intervals where no context switches occur.
