Treffer: GPU acceleration of average gradient method for solving partial differential equations.

Previously presented method of calculating local average gradients for solving partial differential equations (PDEs) is enhanced by accelerating it with graphics processing units (GPUs) and combining a previous technique of interpolating between grid points in the calculation of the gradients instead of using interpolation to create a denser grid. For accelerating the calculation with GPUs, we have ported the original naive Matlab implementation to C++ and CUDA, and after optimizing the code we observe a speedup factors more than two thousand, which is largely due to the original code not being optimized.
