Abstract
We present SES3D, an open-source HPC software package for seismic forward modelling and full-waveform inversion. SES3D is based on a time-domain spectral-element discretisation of the 3D seismic wave equation for anisotropic, visco-elastic media and operates in the natural spherical coordinate system. In our research we aimed at constructing lean, robust, and portable software capable of running on a wide range of modern high-performance computing platforms and accessible for seismologists working in both academic and industrial environments. We address all major performance aspects, which include data-parallel computations, data transfers between distributed computational nodes, and parallel bulk I/O. SES3D can be applied to a wide range of forward and inverse modelling problems on local to continental scales. The application areas include full-waveform inversion, seismic source inversion, forward modelling studies, and sensitivity analysis.
