Abstract

The application of computer simulation models plays a significant role in the understanding of water dynamics in basins. The recent and explosive growth of the processing capabilities of General-Purpose Graphics Processing Units (GPGPUs) has resulted in widespread interest in parallel computing from the modelling community. In this paper, we present a GPGPU implementation of finite-differences solution of the equations of the 2D groundwater flow in unconfined aquifers for heterogeneous and anisotropic media. We show that the GPGPU-accelerated solution implemented using CUDA(1) C/C++ largely outperforms the corresponding serial solution in C/Cthornthorn. The results show that the GPGPU-accelerated implementation is capable of providing up to a 56-fold speedup in the solution using an ordinary office computer equipped with an inexpensive GPU(2) card. The code developed for this research is available for download and use at http://modelagemambientaluffs.blogspot.com.br/. (C) 2017 Elsevier Ltd. All rights reserved.
