Jacek A. Jankowski. UnTRIM parallelization with message passing, 3rd UnTRIM Workshop, Trento, 15-17 May 2006.
This is a second part of the UnTRIM parallelisation project presentations — for the background, see the previous post. The most important issue addressed so far concerns absolving a number of stringent verification tests applied for checking the parallel implementation correctness as well as the user steering of the model.

Jacek A. Jankowski. UnTRIM parallelization with message passing, 2nd UnTRIM Workshop, Sirmione, 23-25 May 2005.
The main ideas behind the parallelisation of UnTRIM applying the domain decomposition method and the message passing (MPI) are discussed. The issues concerning the mesh partitioning, point-to-point communication over the mesh-overlapping areas (halos) for purely triangular and mixed (triangles and quadrangles) meshes and the problems connected with the Lagrangian advection scheme are thoroughly described.

Jacek A. Jankowski. UnTRIM applications for fluvial flows, 1st UnTRIM Workshop, Verona, 7-9 June 2004.
Attracted by the proven and excellent mathematical properties of the scheme and the ongoing OpenMP parallelisation of the UnTRIM code, BAW Karlsruhe has initiated an internal investigation to assess the feasibility of the freshly developed code for the engineering applications concerning river flows.
