Overview
OASIS3 is the direct evolution of the OASIS coupler developed since more than 10 years at CERFACS (Toulouse, France). Portability and flexibility are OASIS3 key design concepts. At run-time, OASIS3 acts as a separate mono process executable, which main function is to interpolate the coupling fields exchanged between the component models, and as a library linked to the component models, the OASIS3 PRISM Model Interface Library (OASIS3 PSMILe).
OASIS3 supports 2D coupling fields only. To communicate with OASIS3, directly with another model, or to perform I/O actions, a component model needs to include few specific PSMILe calls. OASIS3 PSMILe supports in particular parallel communication between a parallel component model and OASIS3 main process based on Message Passing Interface (MPI) and file I/O using the GFDL mpp_io library.
OASIS3 has been extensively used in the PRISM demonstration runs and is currently used by approximately 15 climate modelling groups in Europe, USA, Canada, Australia, India and Brazil.
Download
The last version of the OASIS3 coupler, OASIS3_prism_2-5, including its toy coupled model TOYCLIM, is available from CERFACS CVS server and on CERFACS anonymous ftp. Please note that the PRISM Standard Compiling and Running Environnement (SCE/SRE) are not delivered with this OASIS3 release. Their updated version will be included later when the OASIS development server will migrate from CVS to Subversion within the next months.
To download OASIS3 sources, either from the CVS server or from the anonymous ftp, please contact us and give us your name, the name of your institution, and a description of the coupled configuration (component models) for which you plan to use OASIS3.
