Abstract
The paper considers application of DVM and SAPFOR in order to automate mapping of 3D elastic waves simulation method on high-performance heterogeneous clusters. A distinctive feature of the proposed method is the use of a curved three-dimensional grid, which is consistent with the geometry of free surface. Usage of curved grids considerably complicates both manual and automated parallelization. Technique to map curved grid on a structured grid has been presented to solve this problem. The sequential program based on the finite difference method on a structured grid, has been parallelized using Fortran-DVMH language. Application of SAPFOR analysis tools simplified this parallelization process. Features of automated parallelization are described. Authors estimate efficiency and acceleration of the parallel program and compare performance of the DVMH based program with a program obtained after manual parallelization using MPI programming technology.
