Abstract: 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. The topology view represents the spatial load distribution of the network topology in 3D space. The user can analyze the communication behavior on a specific network topology. A distinction between the behaviors of the new all-to-all communication algorithm and the conventional one is drawn clearly by the tool. In addition to the poster presentation, we are going to present a communication algorithm behavior on PC using our visualization tool.
