# The IPSLCM6 configuration #

IPSLCM6 is '''the configuration of the coupled IPSL model''' under development for the CMIP6 simulations including atmosphere, land, ocean, sea ice and carbon cycle. This configuration includes :
 * the model components:
  * LMDZ, the atmospheric model ; 
  * NEMO, the ocean model including sea ice (LIM2) and marine biogeochemistry (PISCES) ; 
  * ORCHIDEE, the land model ;  
  * the OASIS-MCT coupler ;
 * the tools :
  * XIOS, the I/O server ; 
  * scripts to run the model and to perform post processing and the ksh functions library libIGCM


As a reminder, here are the versions of the components and tools.

# Resolutions and configurations #
One configurations is available :
   * ORCA2xLMD9695-L39.

## IPSLCM6A-VLR ##

By default the coupled version is IPSLCM6A-VLR.

# Ressources on usual machines #

## TGCC ##

### Bull Curie thin nodes ###

The basic configuration uses 128 computing cores or 8 nodes: 1 for XIOS, 19 for NEMO, and 27 MPI and 4 OpenMP for LMDZ. 

## IDRIS ##

### IBM : Ada ###

The basic configuration uses 56 computing cores or 2 nodes: 1 for XIOS, 7 for NEMO, and 24 MPI and 2 OpenMP for LMDZ. 

# Command summary #
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:
{{{
#!sh
mkdir MONREPERTOIRE ; cd MONREPERTOIRE
svn_ano # svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
cd modipsl/util
./model IPSLCM6_rc0
cd ../config/IPSLCM6
gmake # by default ORCA2xLMD9695-L39
cp EXPERIMENTS/IPSLCM5/EXP00/config.card .
vi config.card # modify JobName (at least) : MYJOBNAME, restarts
../../util/ins_job # Check and complete job's header
cd MYJOBNAME
vi Job_MYJOBNAME # modify PeriodNb, adjust the time, headers ...
llsubmit Job_MYJOBNAME # IDRIS
ccc_msub  Job_MYJOBNAME # TGCC
}}}

## Restart files ##
IPSLCM6 configuration could restart from any IPSLCM5A restart file.
