It is interesting for the developers to know who is using the software and for which purpose. Therefore, to obtain instructions on how to download OASIS4 sources , the user first has to fill a registration form available at https://verc.enes.org/models/software-tools/oasis/download/oasis4-registration-form asking for the user identity, whether he/she wants to use OASIS3 or OASIS4, the component models he/she would like to couple with OASIS, whether it is a new coupled model or an upgrade of an exiting one, the target compute platform, and the project. The user can also tick a box if he/she agrees to appear on the OASIS download page and another box if he/she wants to subscribe to OASIS mailing list.
After submitting the form, the user will get detailed instruction on how to download the OASIS4 sources, either from the OASIS SVN server at CERFACS, memphis, or from CERFACS anonymous ftp site. The sources distributed are always the latest ones registered on the SVN trunk. The sources in the tar balls available from the ftp site are automatically update each day.
