The paper describes an optimized GPU based approach for stencil based algorithms. The simulations have been performed for a two dimensional steady state heat conduction problem, which has been solved through the red black point successive over relaxation method. Two kernels have been developed and their performance has been greatly improved through(More)
The paper introduces an optimized GPU based implementation of the incompressible Navier-Stokes equations which are solved using the artificial compressibility method. The numerical scheme is based on a finite difference method. The domain on which the simulations have been performed is a backward facing step problem and the discretizations have been carried(More)
A GPU accelerated implementation of a reduced-order model of the human arterial circulation is introduced. The computationally intensive tasks of the algorithm (namely, the computation of the flow rate and area values at the interior grid points of the domain) have been migrated to the GPU. The CPU not only coordinates the actions performed by the GPU, but(More)
We performed a thorough evaluation of three main implementation types for outflow boundary conditions of one-dimensional blood flow models: the implicit Lax-Wendroff implementation, the explicit Lax-Wendroff implementation and the implicit method of characteristics implementation. The three implementation types have been applied for resistance and(More)
