v45 v46 29 29 '''IPSL-CM5A2 model''' is available at following resolutions/configurations : 30 30 31 * '''IPSL-CM5A2-VLR''' : LMDZ (Old Physics) 96x95x39-ORCHIDEE(Choisnel) - NEMO-LIM2-PISCES ORCA231 * '''IPSL-CM5A2-VLR''' : LMDZ (Old Physics) 96x95x39-ORCHIDEE (Choisnel) - NEMO-LIM2-PISCES ORCA2 32 32 33 33 The 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. … … 79 79 ### Computing performances ### 80 80 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'''. 81 The 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'''. 82 Test on Irène TGCC and Jean-Zay IDRIS still to be done. 82 83 83 84 #### How to run more efficiently (using less resources) #### … … 115 116 116 117 In 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.cardas follows :118 * Modify `config.card` as follows : 118 119 {{{ 119 120 #======================================================================== … … 135 136 ../../libIGCM/ins_job 136 137 }}} 137 * Modify PARAM/namelist_ORCA2_cfg138 * Modify `PARAM/namelist_ORCA2_cfg` 138 139 {{{ 139 140 jpni = 4 ! jpni number of processors following i (set automatically if < 1) … … 141 142 jpnij = 60 ! jpnij number of local domains (set automatically if < 1) 142 143 }}} 143 * submit the job : ccc_msub (or llsubmit) Job_MYJOBNAME 144 * submit the job : ccc_msub (or llsubmit) Job_MYJOBNAME 144 145 145 146 #### Load balancing #### … … 179 180 The 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 : 180 181 * 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_jobcommand as follows :182 * specify the environment you want to use when you do the `../../libIGCM/ins_job` command as follows : 182 183 {{{ 183 184 Hit Enter or give MPI Environment (default is IBM), possible MPI environments are IBM (MPI IBM) and Intel (MPI Intel) :
