To produce SGFs, an explicit 2D/3D elastic finite difference wave propagation code was used.
This MPI-CUDA code is based on a widely-used wave propagation code called AWP-ODC and restructured for high throughput and efficiency on a heterogeneous computing architecture.
Also, educating developers with energy efficient application development techniques including loop unrolling, branch optimization, dead store elimination, value numbering, code inlining, constant propagation, code motion, inter-procedural analysis, and instruction scheduling, greens smartphone operations [33].
By improving the usability of the code, called the Open-source Seismic Wave Propagation Code (OpenSWPC), the numerical simulation with parallel computing of a wide variety of targets is made accessible to users.
We have developed an open-source software package, Open-source Seismic Wave Propagation Code (OpenSWPC), for parallel numerical simulations of seismic wave propagation in 3D and 2D (P-SV and SH) viscoelastic media based on the finite difference method in local-to-regional scales.
In order to produce broadband simulations for the different earthquake scenarios of the PIF, for the frequency range 0.5 20 Hz, the simulations were calculated using by EGFs, and for the frequencies below 0.5 Hz, the simulations were obtained using by SGFs, which were synthetic seismograms calculated by an explicit 2D/3D elastic finite difference wave propagation code (Larsen 1995) named ED3.
This paper discusses various factors related to material interfaces in Lagrangian and Eulerian shock-wave-propagation codes (hydrocodes), which can lead to disagreement between computations and experience.
Since systems using Tomlinson-Harashima precoding do not suffer from error propagation, channel coding can be applied together with precoding with a gain in error performance.
A first application of this combination between an outdoor sound propagation numerical code and an optimization algorithm concerns the optimization of noise barrier caps with the following varying parameters: the cap size, its shape and its surface impedance.
