4/6/2015 : compiler change on Ada-IDRIS
Dear all, Because of bad results with the compilation environment intel/2013.1, we still advise everyone to go back to the previous one, intel/2013.0, as already stated by Laurent Fairhead on May 5th, 2015. We will put this environment back in the default IPSL environment on ada. More precisely, the file ~rpsl035/.bash_login will be modified to point towards the validated environment including intel/2013.0. This will take effect on Tuesday, June 9th, 2015, at 2 pm. If you followed the recommendations (https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocBenvAidris), you won't have anything to do, otherwise use ~rpsl035/.bash_login as a model to modify your own .bash_login file. libIGCM tag v2.6 will also point towards this file. You have to update to this libIGCM tag. See https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocLfaq#HowdoIuseadifferentversionoflibIGCM for more information. Be aware that, even with the environment intel/2013.0, there are still a few errors in some variables with the IPSLCM5A model. We don't support it any more on ada. Please use IPSLCM5_v5 instead, since it has been checked. Have good computations on ada! Don't forget to check your results!

4/6/2015 : Change in compilation and runtime environment on Curie-TGCC
In order to fix problems related to NetCDF writing/reading encountered on scratchdir filesytem on Curie machine, we are going to switch compilation and running environment with new NetCDF version netcdf/4.3.3.1_hdf5_parallel, nco/4.4.6 and cdo/1.6.7. Except for IPSLCM5A model (see below), the change of NetCDF version (switch from 4.2 to 4.3.3.1) has been validated and the reproducibility of the results has been checked for all of models and configurations available through "model" command in modipsl. We strongly advice you to switch with this new compilation and running environment which will be available from June, 9th, 2 pm. To do that, here are instructions to follow : 1) Environment The ~p86ipsl/.bashrc environment file we recommend you to use will be adapted to use the new environment. 1.1) If you already use this file, as suggested in the documentation (http://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocBenvBtgcc#HowtoinstallyourenvironmentonTGCC), you don't have to do anything. 1.2) If you use your own configuration file (.bashrc_curie, .bashrc,...), you have to modify it (by adding the load of new modules) : you can see ~p86ipsl/.bashrc as an example. 2) Compilation and running From June, 9th, 2pm, models and configurations dowloaded thanks to the "model" command of modipsl will be adapted to the new environment. For models and configurations extracted before this date, you will have to : - compile (or compile again after a gmake clean) using the new environment (see 1)). - update your libIGCM version in order to use new tag libIGCM_v2.6. Here is information about the update of libIGCM version: http://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocLfaq#HowdoIuseadifferentversionoflibIGCM Particular case of v6 configurations using XIOS output library : to compile (or compile again) with the new environment, you have to modify following files : - modipsl/modeles/XIOS/arch.env as follows (comment lines ) : #module unload netcdf #module unload hdf5 #module load hdf5/1.8.9_parallel #module load netcdf/4.2_hdf5_parallel - modipsl/modeles/XIOS/arch.path as follows : HDF5_INCDIR="" HDF5_LIBDIR="" HDF5_LIB="" 3) IPSLCM5A : particular case IPSLCM5A model peforms results which are different from NetCDF 4.2 to 4.3.3.2. If you want to keep exactly the same results, don't change anything in your environment and don't update your libIGCM library. If you have any simulations which are running, you have also the possibility to not change anything and to keep the previous environment (beware the automatic change : case 1.1 above) : you have to know there is a risk to obtain corrupted files. A mail will be sent on June, 9th afternoon once all of these changes will be effective. Arnaud
