摘要

3-D finite-difference time-domain (FDTD) models of the global Earth-ionosphere waveguide have reached grid resolutions on the order of 1 × 1 × 1 km and higher. At these high resolutions, efficient parallel input-output (I/O) schemes are required to keep the simulation run times reasonable. However, generating optimal parallel I/O schemes is challenging due to the spherical-coordinate global mesh t...
