Efficient river modelling applying subgrid technology (UnTRIM2)

Two subsequent presentations on the 13th UnTRIM Workshop 2016 with the same title Efficient river modelling applying subgrid technology (UnTRIM2), the first part concerning concept and grids, presented by Regina Patzwahl, and the second part concerning results, presented by Jacek A. Jankowski. Continue reading

Intel Many Integrated Core (MIC) architecture and the UnTRIM code

Intel Many Integrated Core (MIC) architecture and the UnTRIM code, 11th UnTRIM Workshop, Trento, 19-21 May 2014.

The presentation describes the results of an investigation concerning the potential of porting the UnTRIM2 code (with subgrids, see Casulli and Stelling 2010) to the Intel MIC processors, the trade mark name Xeon Phi. Continue reading

Short info: GPU version of the 2Dxy scheme

Short info: GPU version of the 2Dxy scheme, 9th UnTRIM Workshop, Trento, 7-9 May 2012.

The ongoing developments of the GPU-implementation of the 2Dxy semi-implicit scheme for general free surface flows. Moving towards a generic application by providing a user interface and embedding the CUDA computational core in C++ structures, as well as code verification and validation. Continue reading

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

General-purpose GPUs – why interesting?

Jacek A. Jankowski. General-purpose GPUs – why interesting?, 7th UnTRIM Workshop, Trento, 3-5 May 2010.

The philosophy behind the general purpose GPU computing with arguments pro and against is discussed with the background of initiated projects to adapt specific numeric schemes to apply this technology. Continue reading
