    8181The 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'''.

    84  
    85 In order to use less computing ressources, it is possible to run on 160 cores (38 simulated years per day) as follows : 1 process for XIOS, 31 processes for NEMO, and 32 MPI processes and 4 OpenMP thread for LMDZ. To do that, you have to :

    147147Because of load-balancing (difference between ocean computing time and atmosphere computing time), not all of the configurations (in terms of number of process/threads) are efficient.  
    148 If you want to run a configuration with less cores, ask Arnaud Caubel what would be the optimum configuration.
