= 2010: from merge party to 3_3 release = Last edited [[Timestamp]] [[PageOutline]] This page is intended to faciltate the work of the next weeks, i.e. beween the merge party and the release of 3_3. Feel free to edit it to add your informations comments, suggestions.... ---- == 19 october 2010: branch nemo_v3_3_beta created == After the merge party, the branch with all developments of the year is build:[[BR]]This beta version is available using : [[BR]]svn co !https://forge.ipsl.jussieu.fr/nemo/svn/branches/nemo_v3_3_beta/NEMOGCM (read only) [[BR]]!svn+ssh://"your_login"@forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/branches/nemo_v3_3_beta/NEMOGCM (read/write). ---- == List of tests done and results: == Add here test description (Branch nemo_v3_3_beta, Revision2298 (now) , configuration, computer, restartability, ...) ||Description||Revision no||Configuration||Computer||Perf. memory||Perf.
