+# IPSLCM6 model #
+
+You can find [https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocHconfigAipslcm6#IPSLCM6model here] a description for IPSLCM6 model 
+
+The version rc1 (IPSLCM6_rc1) 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. You can find [https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocHconfigAipslcm6#IPSLCM6A-VLR_rc0 here] informations for the VLR (IPSLCM6_rc0) configuration. 
+   * '''IPSLCM6-LR''' (under development, '''not available''') : LMDZ 144x144x79-ORCHIDEE (CWRR) - NEMO-LIM3-PISCES eORCA1xL75
+
+## IPSLCM6-LR_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.
+
+'''IPSLCM6-LR_rc1''' is composed of following components and tools (Sept. 2015) :

+'''Caution''' : this is subject to quick changes !
+
+
+### 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 YOUR_DIRECTORY ; cd YOUR_DIRECTORY
+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
+# ../../util/ins_job -m Intel # on ada after a compilation with Intel 2016.2
+cd MYJOBNAME
+vi Job_MYJOBNAME # modify PeriodNb, adjust the time, headers ...
+llsubmit Job_MYJOBNAME # IDRIS
+ccc_msub  Job_MYJOBNAME # TGCC
+}}}
+
+### 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_PeriodLength.job will remove last period files, i.e last simulated year files.
+
+#### Pack Frequency ####
+Default pack frequency is 1Y, i.e in config.card :
+{{{
+PackFrequency=1Y
+}}}
+
+#### Rebuild frequency ####
+Since we run with XIOS (server mode) as output library, '''the rebuild step is not needed anymore'''.
+
+#### How to add a parameter in NEMO's namelist? ####
+ * let find the parameter in namelist_ref. For example in modeles/NEMOGCM/CONFIG/SHARED/namelist_ice_lim3_ref
+ * let find the namelist's name : for example &namicedyn
+ * let add a line with the new of the parameter in the file PARAM/namelist_lim3_ORCA1_cfg in the &namicedyn section
+
+#### What is the maximum length for a simulation name? ####
+Due to limitation in NEMO, a simulation should have '''less than 39 characters'''.
+
+### 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.
