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 :
As a reminder, here are the versions of the components and tools.
vi modipsl/util/mod.def
One configurations is available :
By default the coupled version is IPSLCM6A-VLR.
The basic configuration uses 128 computing cores or 8 nodes: 1 for XIOS, 19 for NEMO, and 27 MPI and 4 OpenMP for LMDZ.
The basic configuration uses 56 computing cores or 2 nodes: 1 for XIOS, 7 for NEMO, and 24 MPI and 2 OpenMP for LMDZ.
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 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
#MSUB -n 128 # reservation des coeurs pour le job (ce doit etre egal a l'ensemble de process/threads : par exemple 27x4 + 19 + 1 = 128 #MSUB -x # Specifier que le noeud doit être dédié #MSUB -E '--cpu_bind=none'
# Nombre de processus MPI demandes (ici 24 + 7 + 1 = 32) # @ total_tasks = 32 # Nombre de coeurs réellement utilisés (ici 24 x 2 + 7 + 1 = 56) # @ environment = "BATCH_NUM_PROC_TOT=56" # Nombre de taches OpenMP/pthreads par processus MPI # @ parallel_threads = 2

IPSLCM6 configuration could restart from any IPSLCM5A restart file.
Remember to evaluate the files produced by this simulation.
