1. Description

modipsl is a suite of scripts which allow you to

  • obtain a model configuration from a computing center;
  • to compile the model components of a model configuration on a specific machine.

modipsl is also the architecture hosting the models and tools of a chosen model configuration. modipsl is developed at IPSL.

2. Downloading modipsl

svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl

To avoid typing this command line for every new modipsl retrieval, we recommend to create an alias : 

alias svn_ano='svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl'

The retrieval command then becomes 

svn_ano

3. How to use modipsl

3.1. The modipsl directories

After downloading and unpacking modipsl, you should have the following directory structure:

  • util contains information and scripts necessary to setup the different versions of the IPSL models;
  • doc contains the CECILL's license (license of the IPSL models)

modipsl also contains the following directories (empty at the beginning) :

  • modeles: directories containing the model source codes (filled once the model configuration has been downloaded and unpacked)
  • config: directories containing the experiment directories (filled once the model configuration has been downloaded and unpacked: with command: ./model config_name)
  • bin: directory containing the executables (filled after compiling)
  • lib and tmp: directories containing temporary files created during the compilation. Those directories will not be used by all models.

Main scripts in the directory util

  • model --> Downloading script for available model configurations. This script also provides information on the available model configurations.
  • mod.def --> File containing the information on the available model configurations : components, tags, svn servers
  • ins_make --> Install Makefiles for the computing machine
  • ins_job --> Script for running jobs on the computing machine

3.2. Available configurations via modipsl

Using modipsl will give you access to a large number of model configurations, each of them uses one or more IPSL models. To list the available model configurations, use the following script: 

cd modipsl/util
./model -h

To obtain information on the models used (tags, versions,...) in a specific configuration, use the following script: 

./model -h config_name

Example with LMDZOR_v6.1.10 : 

./model -h LMDZOR_v6.1.10
 
model : LMDZOR_v6.1.10

If the requested model configuration does not exist : 

./model -h Ornithorynque
Model Ornithorynque unknown
Try "model -h"

3.3. How to download and use a selected model configuration

Downloading is the recovery of the source codes of the model components of a specific model configuration from different SVN (and CVS) servers. The download can be done with this script: 

./model config_name

When you try to access to the component servers, some of them request a login and a password: ORCHIDEE, NEMO, INCA and REPROBUS. To do so, you must contact the person in charge of the model configuration (see above the list of special cases; model managers email addresses is available via the command model -h)

Example : 

cd modipsl/util
# see all the available configurations
./model -h
# extract the LMDZOR_v5 configuration
./model LMDZOR_v5

The source codes of the downloaded models are in the modipsl/modeles/ directory.

For the previous example you will obtain the following directories :

  • modipsl/modeles/IOIPSL
  • modipsl/modeles/LMDZ
  • modipsl/modeles/ORCHIDEE

modipsl also installs a model configuration. It is installed in the directory modipsl/config/ (here modipsl/config/LMDZOR_v5).
Each model will be compiled and the simulation will be run in the config directory.

The log files of the installation are stored in the modipsl/util/log file.

3.4. Syntax in mod.def

When launching ./model config_name, in mod.def lines starting with

  • #-H- config_name only text information
  • #-M- config_name an email will be sent to the given address only at first extraction at a new machine
  • #-C- config_name code extraction

The code extraction line has the following syntax : 

#-C- config_name  versionOnServer      revisionNumber    depotNumber modelName    dirInModipsl
  • depotNumber is the reference of the repository address for the given code. The full address is set in the beginning of mod.def where all repository addresses are listed starting with #-S- number.
  • versionOnServer is directory to extract find on the current depository address
  • revisionNumber is the revision to extract. If revisionNumber is HEAD, the latest revision on the versionOnServer will be extracted.
  • dirInModipsl is the directory in modipsl where the code will be installed
  • modelName is the name of the installed directory. The code will be find in modipsl/dirInModipsl/modelName

As an example see here an extract from mod.def:

#-H- LMDZ_v5  LMDZ (closest version to IPSLCM5_v5)
#-H- LMDZ_v5  This configuration can be used with LMDZ4(LMDZ4/branches/LMDZ4_AR5) or LMDZ5 (LMDZ5/trunk(default), LMDZ5/branches/LMDZ5_AR5)
#-M- LMDZ_v5  Josefine.Ghattas@ipsl.jussieu.fr
#-C- LMDZ_v5  IOIPSL/tags/v2_2_2/src              HEAD               8  IOIPSL/src modeles
#-C- LMDZ_v5  LMDZ5/trunk                         2076               11 LMDZ       modeles
#-C- LMDZ_v5  CONFIG/UNIFORM/v5/LMDZ_v5           HEAD               8  LMDZ_v5    config
#-C- LMDZ_v5  tags/libIGCM_v2.5                   HEAD               10 libIGCM    .
...

By launching ./model LMDZ_v5, you'll install in directory

3.5. Change a model version

By default the available model configurations use specific model versions. But different versions of a given model can be used with a specific configuration. This is the case for the LMDZ version in the "_v5" configurations. You might want to use the latest version on an LMDZ4/branches/LMDZ4_AR5 branch (used for CMIP5 simulations) or you might want to use the new physics scheme of LMDZ and therefore you will need a more recent version of LMDZ5/trunk. To find out which model version to use, please contact the model development team directly.

If you already know which model version to use, you just have to change the section about the model configuration you selected in modipsl/util/mod.def.

For example with LMDZOR_v5, in mod.def you have the following lines: 

#-C- LMDZOR_v5  tags/ORCHIDEE_1_9_5/ORCHIDEE          HEAD               14 ORCHIDEE   modeles
#-C- LMDZOR_v5  LMDZ5/trunk                           2076               11 LMDZ       modeles

The second column tells the version and third column the revision for this version. If it says HEAD, this means the latest revision. This means that you'll extract ORCHIDEE version tags/ORCHIDEE_1_9_5/ORCHIDEE, latest revision.

For example, to extract the LMDZOR_v5 configuration with the latest revision (HEAD) of LMDZ4_AR5, change mod.def to obtain : 

#-C- LMDZOR_v5 LMDZ4/branches/LMDZ4_AR5     HEAD               11 LMDZ       modeles

or for LMDZ5/trunk revision 1628 : 

#-C- LMDZOR_v5  LMDZ5/trunk                 1628               11 LMDZ       modeles

or to use the "testing" branch of LMDZ with revision 2160: 

#-C- LMDZOR_v5  LMDZ5/branches/testing      2160               11 LMDZ       modeles

You can also change to use a different branch for a model. For example if you want to use the branch ORCHIDEE-DOFOCO in LMDZOR_v5.2 configuration, change to obtain following in mod.def: 

#-C- LMDZOR_v5.2  branches/ORCHIDEE-DOFOCO/ORCHIDEE   HEAD     14 ORCHIDEE    modeles

4. Special cases

  • Reprobus : this model has restricted access via svn+ssh. Click here for more information.
  • Orchidee :
    • If you want to use the trunk of ORCHIDEE, use configuration LMDZOR_v5.2 or ORCHIDEE_trunk(offline)
    • Install LMDZOR and ORCHIDEE_OL with the same modipsl : click here
  • NEMO : this model needs to get an account on ​NEMO website. Required only the first time.
  • INCA : this model needs also to get a specific account.
