Description

SW4 solves the 3-D seismic wave equations in the time domain using a 4th order accurate summation-by-parts finite difference method. SW4 implements a message passing programming model based on MPI and runs on Linux/Unix/OSX machines ranging from laptops to supercomputers with more than a hundred thousand cores.

Notes

This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under contract DE-AC52-07NA27344. This is contribution LLNL-CODE-643337.
