Intel has opened a second parallel computing center at the San Diego Supercomputer Center (SDSC), at the University of California, San Diego. The focus of this new engagement is on earthquake research, including detailed computer simulations of major seismic activity that can be used to better inform and assist disaster recovery and relief efforts.

The new Intel Parallel Computing Center (Intel PCC) continues an interdisciplinary collaboration between SDSC and the Southern California Earthquake Center (SCEC), one of the largest open research collaborations in geoscience. In addition to UC San Diego, the new PCC includes researchers from the University of Southern California (USC), San Diego State University (SDSU), and the University of California, Riverside (UCR).

The Intel PCC program provides funding to universities, institutions, and research labs for modernizing key community computer codes used across a wide range of disciplines to run on current industry-standard parallel architectures. In September 2014, SDSC and Intel announced SDSC’s first such center, focused on improving the parallelism, efficiency, and scalability of widely used molecular and neurological simulation technologies.

The Intel PCC at SDSC for Earthquake Simulation will be an interdisciplinary research center with the goal of modernizing SCEC’s highly scalable 3D earthquake modeling environment, called AWP-ODC. The modernizations will leverage the latest multi-core Intel Xeon processors and many-core, self-hosted, next-generation Intel Xeon Phi processors architecture.

“These are exciting times for computational seismology, as Intel’s new technology and this additional support will help accelerate earthquake modeling research,” said Yifeng Cui, director of the High Performance GeoComputing Laboratory at SDSC. Cui also is an adjunct professor with SDSU, and Principal Investigator for the new Intel PCC at SDSC.

California comprises about three-quarters of the nation’s long-term earthquake risk, and Southern California accounts for nearly 50 percent of the national annualized earthquake loss, according to Federal Emergency Management Agency (FEMA) data. An animation done by Cui and his associates of a magnitude 7.8 earthquake simulation on the San Andreas Fault can be viewed below.

“The primary goal of the software development is to integrate the modernized code elements into a software ecosystem used by SCEC for production size of physics-based seismic hazard analysis in the U.S. and elsewhere,” noted Cui.

“Realistic, physics-based earthquake ground motion computational models can help key decision-makers identify effective ways to reduce seismic risk,” said Thomas Jordan, project co-Principle Investigator and SCEC Director. “This new partnership with Intel provides us the opportunity to substantially broaden the frequency band covered by such detailed simulations, allowing researchers to predict ground motions at frequencies relevant for common dwellings.”

Other members of the SDSC’s new Intel PCC include Alexander Breuer (SDSC), Daniel Roten (SDSU), and Jeffrey Chen (UCR).

“Intel is pleased to collaborate with SDSC in geosciences to help extract the full capability of modern parallel CPUs in wave propagation applications as used in earthquake simulation,” said Joseph Curley, senior director, HPC Platform and Ecosystem Enabling at Intel Corporation.  “By fully exploiting the capabilities of modern CPU technology like the Intel Xeon and Intel Xeon Phi processors, we hope that a greater number of geoscientists will be able to improve their time to results, utilize increased model sizes, and provide a more precise understanding of seismic ground motion to help our society prepare for the next ‘Big One’.”

About SDSC

As an Organized Research Unit of UC San Diego, SDSC is considered a leader in data-intensive computing and cyberinfrastructure, providing resources, services, and expertise to the national research community, including industry and academia. Cyberinfrastructure refers to an accessible, integrated network of computer-based resources and expertise, focused on accelerating scientific inquiry and discovery. SDSC supports hundreds of multidisciplinary programs spanning a wide variety of domains, from earth sciences and biology to astrophysics, bioinformatics, and health IT. SDSC’s Comet joins the Center’s data-intensive Gordon cluster, and are both part of the National Science Foundation’s XSEDE (eXtreme Science and Engineering Discovery Environment) program, the most advanced collection of integrated digital resources and services in the world.
