Network Intensive Grid Computing and Visualization

app imageBased on their SC'2001 work that won the Gordon Bell Prize and the Bandwidth Challenge, these scientists are running an astrophysics simulation at a USA supercomputing center and then computing detailed remote visualizations of the results. One part of the demo shows remote online visualization - as the simulation continues, each time step's raw data is streamed in parallel over the transatlantic network connection to a Linux cluster in Amsterdam for parallel volume rendering. The other part demonstrates remote off-line visualization using advanced grid technologies to efficiently access data on remote data servers, as well as new rendering techniques for network-adaptive visualizations.

This application currently saturates any network given to it, so the scientists work around the limitations. 10Gbps networking can be utilized immediately.
