MODFLOW-2005 version 1.10 with the UPCG solver
The UPCG solver includes support for parallel solution of MODFLOW on (1) multi-core CPUs using OpenMP and (2) general purpose graphical processing units (GPGPUs) using the NVIDIA CUBLAS Library.
Documentation:
Hughes, J.D., and White, J.T., 2012, Use of general purpose graphics processing units with MODFLOW: Ground Water, doi: 10.1111/gwat.12004.
GENERAL USE:
Source code for MODFLOW--2005 with the UPCG solver is available in the code\src subdirectory. A Microsoft Visual Studio solution and associated fortran, C++, and cu projects are available in the code subdirectory.
Development and compilation of CUDA and CUBLAS functions requires installation of the CUDA toolkit which includes the necessary CUDA drivers. NVIDIA also provides GPGPU code samples in the CUDA software development kit (SDK). Current versions of each of these are available free of charge from NVIDIA at http:https://www.nvidia.com/content/cuda/cuda-downloads.html. A 64-bit version of the MODFLOW-2005 executable with the UPCG solver and the linked OpenMP dynamic-link library (DLL) for the Windows 7 operating system and the Tesla C2050 GPGPU is available in the bin subdirectory and only requires installation of the CUDA drivers, which are also available as a stand-alone installation from NVIDIA, and a GPGPU with NVIDIA Compute Capability 2.0 or greater. This executable was linked against version 4.1.28 of the 64-bit CUDA toolkit.
