Poster: Visualization Tool for Development of Topology-Aware Network Communication Algorithm

We develop a visualization tool for designing a topology-aware communication algorithm. This tool visualizes the communication behavior from the logs of a network simulator or an existing parallel computer. Using multiple views, filtering functions, and an animation function, the tool affords users an intuitive understanding of communication behavior and provides statistical information. A distinction between the behaviors of the new all-to-all communication algorithm and the conventional one is drawn clearly by the tool.
