Visualizing program execution using user abstractions
2006
Proceedings of the 2006 ACM symposium on Software visualization - SoftVis '06
Preserved Fulltext
It uses extended finite state automata to model program behaviors in terms of events. It builds time-varying data structures based on these automata. ...
A practical system that uses visualization for understanding the execution of complex programs must offer the user views of the execution that are specific to the program being understood and the particular ...
The amount of data collected must be small enough to move rapidly from the executing program to the visualizer. The data analysis must be done in real time. ...

We have developed a dynamic Java visualizer that provides a view of a program in action with low enough overhead that it can be used almost all the time by programmers to understand what their program ...
Most current dynamic visualizations either use program traces to show information about prior runs, slow the program down substantially, show only minimal information, or force the programmer to indicate ...
Getting Java Trace Data The key to a successful real-time dynamic visualization system is obtaining appropriate trace data with minimal overhead. ...

We propose a multiple-program, multiple-data (MPMD) approach to the in-situ visualization to realize interactive in-situ visualizations. ...
It is semipermeable because information runs in one-way from the simulation to the visualization through the layer, and the layer prevents the simulation program from being affected by visualization program's ...
In most of its execution time, the front face program waits for the new data D n from the simulation program and receives it immediately when it is sent. ...
