Global Array Visualizer

Example output of the Global Array Visualizer.

The Global Array Visualizer is used to animate access patterns to sections of 2-D arrays. The animation uses trace data that is gathered in a file during the program execution. After the animation of events is completed, a composite contention index is displayed.

The Visualizer is intended to help the programmer design efficient task scheduling for MIMD algorithms that operate on 2-D data.
