Description

Output of a parallel discontinuous Galerkin (DG) C++ code that models 3D nonlinear, lossy wave propagation using MPI. Output is in the form of HDF5 files. Each file has the format "variable_processor_timestep.h" where variable is the value being output (either the scalar excess density "dRho", or the 3d vector of particle velocity "vel", or one of the scalar physical constants B/A "ba", diffusion constant "diff", ambient density "rho0", or sound speed "c0"). The second argument in the filename is the MPI core rank that is outputting, and the third argument is the number of the timestep being output. Runtime data (in seconds) is in a seperate text file. This data was used to create the figures in the corresponding paper "Scalable 3D Simulations of Attenuating Nonlinear Acoustic Waves with MPI and the Discontinuous Galerkin Method" by Drew Murray and Robert J. McGough.
