Abstract
--------
The noval radial plot in the *Graph system is used to display communication
in data-parallel programs. Nova visualizations play a valuable role in
understanding how virtual communication in data-parallel programs
translates into network communication, and how source code modifications
and data layout change physical communication patterns. A case study
demonstrates how *Graph nova views are used to visualize and reduce
network communication.
