IPSLCM5_v5 is the reference configuration of the coupled IPSL model for the CMIP5 simulations including atmosphere, land, ocean, sea ice and carbon cycle. This configuration includes :
The ocean configuration is ORCA2 : global ocean with a tripolar grid with one South Pole, one North Pole above Siberia and one North Pole above northern America. The resolution is 2°. In the tropical region, the latitudinal resolution decreases to 1/2°. There are 31 vertical levels.
As a reminder, here are the versions of the components and tools.

Three configurations are setup and used for CMIP5. They all have 39 vertical levels for the atmosphere component. The horizontal resolution of the atmosphere and the atmospheric physics differ:
Other resolutions exist as benchmarks but they are not setup.
By default the coupled version is IPSLCM5A-LR.

The EXPERIMENTS directory contains the benchmark experiments. They are stored in 3 subdirectories: LMDZ, LMDZOR and IPSLCM5.
Reminder: it is possible to perform LMDZ-type (atmosphere only) or LMDZOR-like (atmosphere and land) experiments with executables of this configuration. See LMDZOR

IPSLCM5A-LR has been used at LSCE for glacial climates (21 ka BP, contact Masa Kageyama or Olivier Marti), mid-Holocene (4 ka BP, 6 ka BP and 9 ka BP, contact Olivier Marti or Pascale Braconnot) and for other ancient climates configurations.
Equivalent to historical with interactive CO2 (contact Patricia Cadule or Laurent Bopp). The model is forced with estimations of fossil emissions during the historical period. The CO2 atmospheric concentration results from the equilibrium between prescribed emissions (fossil), carbon absorption by the ocean (PISCES) and the terrestrial biosphere (ORCHIDEE).
Equivalent to piControl with interactive CO2 (contact Patricia Cadule or Laurent Bopp). Control simulation.
You must take the time to identify the initial states used by the model.
A few files allowing you to start your own simulations have been copied at TGCC and at IDRIS :

The pack period is configured in config.card. A larger pack period allows you to reduce the number of files but in case your simulation stops, you must restart the whole period.

The basic configuration uses 32 computing cores: 1 for the OASIS coupler, 5 for NEMO, and 26 for LMDZ. The configuration is regularly used and evaluated on this machine: http://webservices.ipsl.jussieu.fr/trusting/
Here are the commands you need to know if you want to retrieve and compile the IPSLCM5_v5 model and if you want to setup and run an EXP00/pdControl experiment:
mkdir YOUR_DIRECTORY ; cd YOUR_DIRECTORY svn_ano # svn co http://forge.ipsl.fr/igcmg/svn/modipsl/trunk modipsl cd modipsl/util ./model IPSLCM5_v5 cd ../config/IPSLCM5_v5 gmake # by default ORCA2xLMD9695-L39 cp EXPERIMENTS/IPSLCM5/EXP00/config.card . vi config.card # modify JobName (at least) : MYJOBNAME ../../util/ins_job # Check and complete job's header cd MYJOBNAME vi Job_MYJOBNAME # modify PeriodNb, adjust the time, ... llsubmit Job_MYJOBNAME # IDRIS ccc_msub Job_MYJOBNAME # TGCC
