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.
