Assessment of a parallel implementation of a two-dimensional scheme for free surface flows using a GPU

J.A. Jankowski

Abstract: The rapid changes in the present computer architectures throw questions concerning the future of the hardware-oriented programming based on the usage of heterogeneous parallel computing resources, consisting of nodes of interconnected, but separate CPUs and GPUs. However, it is believed that the sustainability of the programming efforts nowadays is to be searched in the fact that the principle source of the performance of the present GPUs as well as the emerging APUs is the hardware acceleration of vector operations. Therefore, this contribution delivers an assessment of a hardware-accelerated parallel implementation of a principal algorithm for a vertically integrated finite difference scheme for free surface flows including non-linear treatment of wetting and drying.

Bringing the principal 2Dxy scheme to a GPU

Jacek A. Jankowski. Bringing the principal 2Dxy scheme to a GPU, 8th UnTRIM Workshop, Trento, 9-11 May 2011.

The first part of the presentation concerns the process of finding an optimal GPU porting method for the principal two-dimensional, vertically integrated semi-implicit scheme for general free surface flows. Continue reading
