Example showing an even-odd exchange sort. The left image is unmodified and the intermediate result is shown. The duplication of pixel values is evident, a result of intermediate calculations. The middle image shows the expected visual without the duplication of pixel values. The right image shows the instrumentation control window and the available commands, accessed from the right mouse button.

... reduce or even remove these artifacts the user can remove display updates from their default locations and force display updates at other locations. An example of this is shown in Fig. 4 in which an even-odd exchange sort is shown. The default instrumentation instructions cause updates to occur for intermediate results which generate unexpected displays. Our ability to interactively modify instrumentation instructions while the program is running extends most work to date that has either incorporated full ...
