Interactive Remote Visualization across the LONI and the National LambdaRail

Interactive visualization coupled with computing resources and data storage archives over optical networks enhance the study of complex problems, such as the modeling of black holes and other sources of gravitational waves.

At iGrid, scientists visualize distributed, complex datasets in real time. The data to be visualized is transported across the Louisiana Optical Network Initiative (LONI) network to a visualization server at LSU in Baton Rouge using state-of-the-art transport protocols interfaced by the Grid Application Toolkit (GAT) and dynamic optical networking configurations. The data, visualization and network resources are reserved in advance using a co-scheduling service interfaced through the GAT. The data is visualized in Baton Rouge using Amira, and HD video teleconferencing is used to stream the generated images in real time from Baton Rouge to Brno and to San Diego. Tangible interfaces, facilitating both ease-of-use and multi-user collaboration, are used to interact with the remote visualization.
