Resumen:
Demonstration runs consist of a set of short experiments (most of them covering 1 model year of simulation),documenting the technical functioning, the usability and the correctness of the approach. Asa first step we demonstrate the portability of the PRISM coupler by integrating the TOYCLIM systemon different platforms. The TOYCLIM system is a combination of toy global models (i.e., empty models,in which no physics is included) but for which both coupling communication and interpolation arerealistic, representing the atmosphere (TOYATM), the ocean (TOYOCE) and the atmospheric chemistry(TOYCHE), and using OASIS3 software. The portability of the PRISM standard coupler OASIS3 andPRISM Standard Compiling and Running Environements (SCE, SRE) was demonstrated by integratingthe OASIS3 TOYCLIM system on different platforms and documented on PRISM Report Series 13.After that we demonstrate that the system is capable of coupling two real general circulation models(GCMs). We document that coupled combinations are successfully integrated and that PRISM systemfulfills several technical requirements, concerning coupling functionalities and scripting environment. Thetechnical aspects that have been demonstrated are the following: The portability The reproducibility, employing different numbers of CPUs The frequency of communication The frequency for archiving output files The restartabilityFurthermore, we have extended the test of portability to some real model combinations which are integratedon several platforms. Later, some specific coupling configurations are demonstrated: an atmosphericregional downscaling over the Northern Europe and two ocean biogeochemistry models on ageneral ocean circulation model.All those experiments are just technical demonstrations, which consist of short experiments coveringno more than 1 model year of integration, demonstrating the technical functioning, the usability and thecorrectness of the approach.
