10. BUNDESANSTALT FÜR WASSERBAU Karlsruhe Hamburg Ilmenau BAW - DH / 2014-04 Folie-Nr. 10 2. Portation of OpenMI Environment 1 OpenMI Standard What has been ported to Mono C#? See Portation Guidelines on the OpenMI Wiki: http://public.deltares.nl/display/OPENMI/How+to+port+the+OpenMI+from+Windows+to+Linux http://public.deltares.nl/display/OPENMI/How+to+port+the+OpenMI+from+Windows+to+Linux C# models of the Examples area SDK, the toolkit Configuration Editor, the GUI Annotations easy portation, some MS dlls could even be interpreted on Mono Common Language Runtime some problems with namespaces, ressource files *.resx, graphic formats; apart from filters all has been ported

Portation of OpenMI Environment 2 Courtesy Rob Knapen from Alterra The dlls were compiled and successfully tested under SUSE SLED 11. Second test of the same dlls on the Mono CLR of Ubuntu 9.04: Download of OpenMI environment from SourceForge http://openmi.svn.sourceforge.net/viewvc/openmi/branches/OpenMI-Version-1-Trunk/

Portation of a Fortran Engine … Intel compiler bug with dlls caused minor changes in the code updated code could be compiled on Windows as well as on Linux Linux and Windows compiler were both Intel compilers the generated shared library (dll) is planned to be re-used as a reader of BAW files for visualisation software Davit … to Linux

14. BUNDESANSTALT FÜR WASSERBAU Karlsruhe Hamburg Ilmenau BAW - DH / 2014-04 Folie-Nr. 14 2. Portation of a C# Wrapper Most of the ported code runs on Windows as well. But a severe Mono bug with accessing Fortran strings -> workaround: Microsoft C# Wrapper and Mono C# Wrapper should differ in that point. The C# Wrapper does not work with parallel Fortran code for HPC; Mono compiler does not support parallel computing. MPI.NET is a commercial product which should enable parallel code for Mono. IDE MonoDevelop not as powerful and well documented as MS Visual Studio Recommendation: Develop in MS Visual Studio.NET and port the results. … to Mono
