You can find here a description for IPSLCM6 model
The version rc1 (IPSLCM6_rc1) runs on Curie-TGCC thin nodes.
IPSLCM6 model will be available at different resolutions/configurations :
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 !
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):
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
Not available yet. Waiting for reference simulations.
By default, only monthly outputs and low output levels are activated.
Default period length is 1Y, i.e in config.card :
PeriodLength=1Y
Note that clean_PeriodLenght.job will remove last period files, i.e last simulated year files.
Default pack frequency is 1Y, i.e in config.card :
PackFrequency=1Y
Since we run with XIOS (server mode) as output library, the rebuild step is not needed anymore.
Due to limitation in NEMO, a simulation should have less than 39 characters.
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.
