    2929'''IPSL-CM5A2 model''' is available at following resolutions/configurations : 
    3030 
    31    * '''IPSL-CM5A2-VLR''' : LMDZ(Old Physics) 96x95x39-ORCHIDEE(Choisnel) - NEMO-LIM2-PISCES ORCA2 
     31   * '''IPSL-CM5A2-VLR''' : LMDZ (Old Physics) 96x95x39-ORCHIDEE (Choisnel) - NEMO-LIM2-PISCES ORCA2 
    3232 
    3333The resolution of LMDZ is 96x95 (3.75° in longitude and 1.875° in latitude) with 39 vertical levels. The ocean configuration is ORCA2 : 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 2°. In the tropical region, the latitudinal resolution decreases to 1/2°. There are 31 vertical levels.

    81 The basic configuration (default configuration) runs on Curie TGCC and Ada IDRIS machine and uses '''302 computing cores''' : 1 process for XIOS, 45 processes for NEMO, and 32 MPI processes and 8 OpenMP thread for LMDZ. This configuration allows you to run '''56 simulated years per day'''.  
     81The basic configuration (default configuration) ran smoothly on Curie TGCC and Ada IDRIS machine and uses '''302 computing cores''' : 1 process for XIOS, 45 processes for NEMO, and 32 MPI processes and 8 OpenMP thread for LMDZ. This configuration allows you to run '''56 simulated years per day'''.  
     82Test on Irène TGCC and Jean-Zay IDRIS still to be done.

    8384#### How to run more efficiently (using less resources) #### 
     
    115116 
    116117In order to run faster (using more computing resources), it is possible to run on 437 cores (66 simulated years per day) as follows : 1 process for XIOS, 60 processes for NEMO, and 47 MPI processes and 8 OpenMP thread for LMDZ. To do that, you have to : 
    117  * Modify config.card as follows : 
     118 * Modify `config.card` as follows :

    145146#### Load balancing #### 
     
    179180The basic configuration (default configuration) runs on Ada (IDRIS). In order to use efficiently computing resources, you have to use Intel environment. To do that you have to : 
    180181 * ask IDRIS assistance (mail to assist@idris.fr) to be authorized to use Ada full node and (# @ node = N) option.  
    181  * specify the environment you want to use when you do the ../../libIGCM/ins_job command as follows : 
     182 * specify the environment you want to use when you do the `../../libIGCM/ins_job` command as follows :
