At the San Diego Supercomputer Center (SDSC) at the University of California San Diego, Caltech computational seismologist Jeroen Tromp can give the public movies that tell the story about earthquakes in a language that's easy to understand, revealing waves of ground motion spreading out from the earthquake. He can deliver these movies in just 30 minutes with the help of a supercomputer at SDSC, which has introduced OnDemand, a new supercomputing resource that will support event-driven science.
"This is the first time that an allocated National Science Foundation (NSF) TeraGrid supercomputing resource will support on-demand users for urgent science applications," said Anke Kamrath, director of user services at SDSC. In addition to supporting important research, the system will serve as a model to develop on-demand capabilities on additional TeraGrid systems in the future. TeraGrid is an NSF-funded computing grid linking some of the nationÃs largest supercomputer centers.
Event-driven applications that will use OnDemand include making movies of Southern California earthquakes, systems that will help give near-real-time warnings based on predictions of tornado or hurricane paths, and predicting the most likely direction of a toxic plume released by an industrial accident or terrorist incident.
