CUDA parallelization. When the number of GPU devices is less than that of CPU cores, one can easily devise a scheme to divide the GPU devices amongst the CPU cores. Each (OpenMP) master thread communicates with its assigned GPU device via CUDA and with other master threads via MPI, as described in Fig. 1 (a) The Wolfram Language provides a uniquely integrated and automated environment for parallel computing. With zero configuration, full interactivity, and seamless local and network operation, the symbolic character of the Wolfram Language allows immediate support of a variety of existing and new parallel programming paradigms and data-sharing models An effective parallelization algorithm based on the compute-unified-device-architecture (CUDA) is developed for DEM generalization that is critical to multi-scale terrain analysis.
