Flood of data can help prevent hurricane damage


When the National Hurricane Center issues a hurricane advisory, emergency teams have little time to predict the locations and effects of storm surges and waves in order to identify areas that should evacuate. A prototype system, known as the Southeastern Universities Research Association Coastal Ocean Observing and Prediction (SCOOP) program, promises to run hurricane computer simulations and produce results quickly.

The complex hurricane models crunch very large data sets, and the data must move from storage to compute resources and back as quickly and reliably as possible. The SCOOP program relies on the Stork Data Scheduler software package — so called because it delivers data — to manage data placement and movement. Developed by researchers at Louisiana State University and the University of Wisconsin-Madison, and made freely available for download, Stork allows researchers to efficiently store, access, share and transfer large data sets.

“There are 80 or more model configurations that we currently run very quickly for our hurricane predictions, and efficient and reliable data movement is extremely important,” said Gabrielle Allen, SCOOP collaborator and associate professor at the Louisiana State University Center for Computation and Technology and Department of Computer Science. “Stork automatically chooses the best parameters and transport mechanisms so the data is transferred in the most efficient way.”

Malthus Embrace failure!

As more powerful systems encompass ever-increasing numbers of components, even a small fault rate on individual processors will generate multiple faults across the components, stopping long-running applications in their tracks.

How to avert a Malthusian Catastrophe?

Gridjam: live, distributed, art-and-music fusion

Gridjam brings together a visual artist, a composer, musicians and computer scientists in a live, 3D visualized, musical performance.  It uses a computational system to visually illustrate the information contained in the musical score, the composer’s instructions to the musicians, and the musicians’ contributions to the score as they improvise in reaction to each others’ performances and to the immersive visual experience.
