1.1. IPSLCM

The default configuration LR is close to IPSLCM6.1 described in IPSLCM6.1 configuration.

  • To compile you will use the target the command ./compile_ipslcm6.sh (see below for more details on compilation)
  • For the experiments, you can choose between EXPERIMENTS/IPSLCM/pdControl_TEST and EXPERIMENTS/IPSLCM/piControl_TEST

1.2. IPSLESM

This configuration allows coupling with CO2 cycle or interactive aerosols calculated by Inca model.
On this page we will describe how to use these 2 existing ESM configurations : ESMCO2 and ESMAER

2. Technicals Details

2.1. How to use it

To retrieve the configuration :

mkdir YOUR_DIRECTORY ; cd YOUR_DIRECTORY
svn_ano    # svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
cd modipsl/util
./model  IPSLCM6.2_work
cd ../config/IPSLCM6.2

The compilation slightly differs from what has been done so far. Now we used a script named compile_ipslcm6.sh with several option ( resolution, level of optimisation, full or partial recompilation ) to compile the model

########################################################################
# Usage of the script compile_ipslcm6.sh
#
########################################################################

./compile_ipslcm6.sh [Options] 


Options: [LR / VLR / MR1 / MR025] Model resolution, choose only one. Default: LR.
         [ESMCO2] Compile IPSLCM6 for CO2 interactif ocean/atmosphere.
         [ESMAER] Compile IPSLCM6 for AER interactif on atmosphere
         [-full] Full recompilation of all components. This option can be added to all other options.
         [-cleannemo] Full recompilation of NEMO component  only.
         [-debug / -dev / -prod] Level of optimization. One of these can be added to all other compile options. Default: -prod.


Example 1: Default compilation of IPSLCM6 for resoltion LR 
          (Resolution atmos: 144x142x79, ocean: ORCA1)
./compile_ipslcm6.sh

Example 2: Compilation of IPSLCM6 for resolution MR025
           (atmos: 256x256x79, ocean: ORCA025, NOPISCES)
./compile_ipslcm6.sh MR025

Example 3: Compilation of IPSLCM6 for ESM CO2
./compile_ipslcm6.sh ESMCO2 -cleannemo

Example 4: Default resoltuion (LR) compiled in debug mode
./compile_ipslcm6.sh -debug

Example 5: Default compilation with full recompilation of all components. No clean is needed.
./compile_ipslcm6.sh -full

Example 6: Full recompilation of resolution MR05 in debug mode
./compile_ipslcm6.sh MR025 -debug -full

To compile and create the Job for ESMCO2

./compile_ipslcm6.sh ESMCO2

cp EXPERIMENTS/IPSLESM/CO2/piControl_TEST/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 ...
sbatch Job_MYJOBNAME # IDRIS
ccc_msub  Job_MYJOBNAME # TGCC

To compile and create the Job for ESMAER

./compile_ipslcm6.sh ESMAER

cp EXPERIMENTS/IPSLESM/AER/piControl_AER_TEST/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 ...
ccc_msub  Job_MYJOBNAME # TGCC

2.2. Restart files

  • ESMCO2 configuration starts from IPSLCM6 CM61-pre-pi-01 simulation (1849-12-31) available from RESTART/IPSLCM6/PROD/piControl-spinup for all the components, except for the Coupler. The latter is taken from $CCCSTOREDIR/../../gencmip6/p86cadul/IGCM_OUT/IPSLCM6/PROD/piControl-spinup/
  • ESMAER configuration starts from IPSLCM6 CM61-pre-pi-01 simulation (1849-12-31) available from RESTART/IPSLCM6/PROD/piControl-spinup for all the components, except for the atmosphere. The latter is taken restart of the same simulation adding the concentration fo tracers for Inca aerosols configuration. This specific restart file is actually store on p24cozic account.

2.3. Output level

By default, only monthly outputs and low output levels are activated.

2.4. Lengths, frequencies

2.4.1. 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.

2.4.2. Pack Frequency

Default pack frequency is 1Y, i.e in config.card :

PackFrequency=1Y

2.4.3. Rebuild frequency

Since we run with XIOS (server mode) as output library, the rebuild step is not needed anymore.

2.5. How to add a parameter in NEMO's namelist?

  • let find the parameter in namelist_ref. For example in modeles/NEMOGCM/CONFIG/SHARED/namelist_ref
  • let find the namelist's name : for example &namicedyn
  • let add a line with the new of the parameter in the file PARAM/namcouple_ESMCO2_ORCA1xLMD144142 in the &namicedyn section

2.6. What is the maximum length for a simulation name?

Due to limitation in NEMO, a simulation should have less than 39 characters.

2.7. Computing centres

This configuration runs on TGCC-Irene-SKL and at IDRIS-JeanZay.

2.7.1. TGCC Bull Curie thin nodes (not anymore in service)

  • ESMCO2 : Default configuration on 929 cores allows you to run 13 simulated years per day.

2.7.2. IDRIS-JeanZay

Because of JeanZay architecture (computing nodes based on sockets of 20 cores), we advice you to use 2, 4, 5, 10 or 20 OpenMP threads for LMDZ-ORCHIDEE component. By default, the number of OpenMP threads defined in config.card is 8. To change that, you have to edit and modify config.card as follows :

[Executable]
#D- For each component, Real name of executable, Name of executable for oasis
ATM= (gcm.e, lmdz.x, 71MPI, 10OMP)

Do not forget to install a new Job (command ins_job) in order to take into account these modifications.
