Researchers using the Cori supercomputer at the Lawrence Berkeley National Laboratory's National Energy Research Scientific Computing Center (NERSC) have achieved record-setting seismic simulations, and presented their studies at this week's ISC High Performance (ISC17) conference in Frankfurt, Germany.

One of the presentations details a new seismic software program, developed by researchers at the San Diego Supercomputer Center, which enabled the fastest seismic simulation ever run to date. The simulations were conducted using a new software system called Extreme-Scale Discontinuous Galerkin Environment (EDGE), a solver package for fueled seismic simulations.

Another paper focused on a new study of the AWP-ODC software, which has been used by the Southern California Earthquake Center for years.

These simulations, which also used the Cori KNL system, achieved competitive performance to an equivalent simulation on the entire graphics-processing unit-accelerated Titan supercomputer at Oak Ridge National Laboratory.
