+# IPSLCM6 model #
+
+IPSLCM6 is '''the IPSL coupled climate model''' under development for the CMIP6 simulations including atmosphere, land, ocean, sea ice and carbon cycle. This model includes :
+ * model components :
+  * '''LMDZ''' as atmospheric model ; 
+  * '''NEMO''' as ocean model including sea ice (LIM2/LIM3) and marine biogeochemistry (PISCES) ; 
+  * '''ORCHIDEE''' as land model ;  
+ * tools :
+  * '''OASIS3-MCT''' as parallel coupler ;
+  * '''XIOS''' as I/O library ; 
+  * '''libIGCM''' as running environment (scripts) to run the model and to perform post processing ;
+This model runs on '''Curie-TGCC thin nodes'''.

+
+# Resolutions and configurations #
+
+IPSLCM6 model will be available at different resolutions/configurations :
+
+   * '''IPSLCM6A-VLR_rc0''' : LMDZ(Old Physics) 96x95x39-ORCHIDEE (Choisnel) - NEMO-LIM2-PISCES ORCA2
+   * '''IPSLCM6-LR''' (under development, '''not available''') : LMDZ 144x144x79-ORCHIDEE (CWRR) - NEMO-LIM3-PISCES eORCA1xL75
+
+## IPSLCM6A-VLR_rc1 ##
+
+The resolution of LMDZ is 144x142 (2.5° in longitude and 1.5° in latitude) with 79 vertical levels. The ocean configuration is eORCA1L75 : 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 1°. In the tropical region, the latitudinal resolution decreases to 1/2°. There are 76 vertical levels, with 1m resolution near the surface, and 200m in the abyss. 
+
+For LMDZ, the new physics is used. Current test (Sept. 2015) is NP 5.17h.
+

+
+### How to use it ###
+Here are the commands you need to know if you want to retrieve and compile the IPSLCM6 model and if you want to setup and run a piControl experiment (only piControl experiment is available):
+{{{
+#!sh
+mkdir MONREPERTOIRE ; cd MONREPERTOIRE
+svn_ano # svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
+cd modipsl/util
+./model IPSLCM6_rc1
+cd ../config/IPSLCM6
+gmake IPSLCM6-LR
+cp EXPERIMENTS/IPSLCM6/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
+}}}
+
+#### Specific command on TGCC Bull Curie thin nodes ####
+
+The basic configuration (default configuration) uses '''598 computing cores''' or 38 nodes: 1 process for XIOS, 221 processes for NEMO, and 47 MPI processes and 8 OpenMP thread for LMDZ. 
+You have to modify header of the Job script as follow : 
+{{{
+#MSUB -n 598 # number of cores used by the Job (equal to the total number of process/threads : for example 47X8 + 221 + 1 = 598)
+#MSUB -x # Specify the node is not shared 
+#MSUB -E '--cpu_bind=none'
+}}}
+
+
+and config.card as follows :
+
+{{{
+#========================================================================
+#D-- Executable -
+[Executable]
+#D- For each component, Real name of executable, Name of executable for oasis
+ATM= (gcm.e, lmdz.x, 47MPI, 8OMP)
+SRF= ("" ,"" )
+SBG= ("" ,"" )
+OCE= (opa, opa.xx  , 221MPI)
+ICE= ("" ,"" )
+MBG= ("" ,"" )
+CPL= ("", "" )
+IOS= (xios_server.exe, xios.x, 1MPI)
+}}}
+
+### Restart files ###
+Not available yet. Waiting for reference simulations.
+
+### Output level ###
+By default, only '''monthly outputs''' and '''low output levels''' are activated.
+
+### Lengths, frequencies  ###
+#### Period length ####
+Default period length is 1Y, i.e in config.card :
+{{{
+PeriodLength=1Y
+}}}
+Note that clean_month.job will remove last period files, i.e last simulated year files.
+
+#### Pack Frequency ####
+Default pack frequency is 10Y, i.e in config.card :
+{{{
+PackFrequency=10Y
+}}}
+Note that since clean_year.job works on the latest pack period, clean_year.job will remove files from latest 10Y pack period. clean_year.job can also be used several time in a row to delete several 10Y pack
+periods.
+
+#### Rebuild frequency ####
+Since we run with XIOS (server mode) as output library, '''the rebuild step is not needed anymore'''.
+
+### Computing centres ###
+
+#### TGCC Bull Curie thin nodes ####
+
+Default configuration on '''598 cores''' allows you to run '''3 simulated years per day'''. Because of load-balancing (difference between ocean computing time and atmosphere computing time), not all configurations (in terms of number of process/threads) are efficient. If you want to run a configuration with less cores, ask Arnaud Caubel what would be the optimum configuration.
