The presentation summarizes in a rather informal and philosophical, but thoroughly informative way the development history of the MPI version of UnTRIM ten years after finalizing the parallel code applied subsequently for practical projects at BAW.
Transparencies from the talk delivered on 15th UnTRIM Workshop in Trento (28-30th May 2018) are available.

German Abstract: Es wird eine neue Modellierstrategie zur Effizienzsteigerung rechenintensiver Simulationen von Flüssen vorgestellt. Der Ansatz kombiniert einen semi-impliziten Subgrid-Ansatz zur Berücksichtigung von hochaufgelösten Geländeinformationen auf gröberen Netzen mit einer auf Hierarchischen-Netzen basierenden Strategie.

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

Abstract: We present a new modelling strategy for improving the efficiency of computationally intensive flow problems in environmental free-surface flows. The approach combines a recently developed semi-implicit subgrid method with a hierarchical grid solution strategy. Continue reading
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
