SCEC TeraShake - Supporting an Earthquake Storage Intensive Simulation

Marcio Faerman San Diego Supercomputer Center

TeraShake, a Southern California Earthquake Center Community Modeling Environment (SCEC/CME) compute and storage intensive simulation, models a large earthquake occurring on the southern San Andreas Fault in California. There is significant interest in modeling earthquakes in Southern California and Northern Mexico. The simulation is based on the Anelastic Wave Propagation Model code, developed by Kim B. Olsen from San Diego State University. The code, enhanced during the TeraShake effort, is now available to the earthquake community.

The simulation, modeled on a rectangular 3000 x 1500 x 400 mesh with 1.8 billion points, will run 20,000 time steps at the San Diego Supercomputer Center (SDSC) DataStar machine. Each step can produce a 21.6GByte snapshot containing ground motion velocity vectors. A 4D wavefield containing 2,000 snapshots, amounting to 43TBytes of data, will be generated at SDSC. Surface data will be archived every step for synthetic seismogram engineering analysis, totaling 1 Tbyte.
