The visual display of parallel performance data

Several performance visualization tools have demonstrated that helpful insights into parallel performance can be gained through graphical displays. However, much of this work has been experimental, specialized, and ad hoc. Evolving performance visualization into an integral, productive tool for evaluating parallel performance requires a more systematic, formal methodology that relates behavior abstractions to visual representations in a more structured way. We propose a high-level abstract model for the performance visualization process, explain its relationship to the most important concepts and principles of effective visualization practice, and illustrate the relationship between these concepts and our abstract model through specific case studies. We also discuss the relationship of performance visualization to general scientific visualization
