Coconut Creek (Florida), ISSN 0749-0208. Graphic Processing Units (GPU) have a number of arithmetic units and their associated structures specialized for graphic processes make the computational performances much faster than CPU (Central Processing Units). In these days, many numerical models implemented by FORTRAN have been applied on real field scale problems, which requires huge computational resources and simulation time as well. In this study, a GPU version of Boussinesq equation model was implemented using the Compute Unified Device Architecture (CUDA) FORTRAN. The computed results of the GPU-CUDA FORTRAN Boussinesq model were verified by comparing with th...
