  2. Southern California Earthquake Center • Earthquake moving along a simple faultline • Two snapshots from the simulation • Birds-eye view of the movement of the ground • Images are colored using a simple transfer function • Blue representing slow moving material • Red fast moving material • Green material moving at speeds in-between the two extremes • Dataset consists of 600 1.1 GB files • 3000 timesteps • Data generated on TG Linux • Recall time sequence data randomly SCEC: Geoff Ely Prof Jean-Bernard Minster SDSC Marcio Faerman Steve Cutchin

  3. Other Relevant Visualizations

  4. GridFTP • A secure, robust, fast, efficient, data transport protocol. • A proposed standard in the Global Grid Forum. • The Globus Alliance provides a reference implementation. • The striped server used in this demo is a prototype, but striping will be available in a production release next mid next year.

  5. Striped Server • Multiple nodes work together and act as a single GridFTP server • An underlying parallel file system stores blocks of the file, usually in round robin fashion, across all of the nodes. • Each node then moves only the pieces of the file that it is responsible for. • The other side then writes the file in the same way, block round robin on a parallel file system. • This allows multiple levels of parallelism, CPU, bus, NIC, disk, etc.
