<p>As the number and diversity of distributed teams grow, the need for visualization tools to analyze and display multiterabyte, remote data becomes more pronounced and more urgent. Visapult is a parallel visualization tool that employs grid-distributed components, latency tolerant visualization, and graphics algorithms, along with high performance network I/O for effective remote analysis of massive datasets. The article discusses improvements to network bandwidth utilization and responsiveness by the Visapult application. These improvements result from use of connectionless protocols to move data payload between distributed Visapult components and a grid-enabled, high-performance physics simulation that helps study gravitational waveforms of colliding black holes (known as the Cactus code).</p>
