    435 ==== Running NEMO ==== 
     436==== Running NEMO-CICE ==== 
    436437 
    437438After NEMO and CICE have been configured they are run (using MPI).  
     
    469470=== Stage 2: NEMOVAR === 
    470471 
     472The two most important scripts in this case are `init_nemovar.sh` and `run_nemovar.sh`.  
     473 
     474 
     475 
    471476 
    472477=== Stage 3: IAU === 
    473478 
    474  
    475  
    476  
     479As with the Obsoper stage, `run_nemo_cice` governs the IAU stage.  
     480Many of the same actions are performed.  
     481 
     482 
     483 
     484==== Configuring NEMO ==== 
     485 
     486Firstly the directory `$CYLC_TASK_WORK_DIR/fluxes` is created.  
     487Flux files from `$ROSE_DATAC/fluxes` are softlinked into this directory (in the script this directory is called `$INDIR_FLUXES`; in `suite.rc` this points to `$FLUX_DIR` which itself points to `$ROSE_DATAC/fluxes`).  
     488 
     489The ancillary files, background restarts and increments (produced by NEMOVAR) are also softlinked into `$CYLC_TASK_WORK_DIR`.  
     490 
     491The coordinate and geothermal files are also linked, once per processor (192 by default).  
     492 
     493`update_namelist` is used to add a few more variables to the `namelist` (the same ones set for Obsoper).  
     494 
     495 
     496 
     497==== Configuring CICE ==== 
     498 
     499CICE is configured in exactly the same way as during the Obsoper stage.  
     500 
     501 
     502 
     503==== Running NEMO-CICE ==== 
     504 
     505After NEMO and CICE have been configured they are run (using MPI).  
     506 
     507When the job finishes the NEMO restarts and pcbias files are linked: 
     508{{{ 
     509ln -sf $CYLC_TASK_WORK_DIR/${RUNID}o_$(printf "%08d" ${TIME_STEPS_PER_CYCLE})_analysis_restart_${printf "%04d" $i}.nc  
     510$OUTDIR_ANALYSIS_RESTARTS/restart_$(printf "%04d" $i).nc 
     511ln -sf $CYLC_TASK_WORK_DIR/${RUNID}o_$(printf "%08d" ${TIME_STEPS_PER_CYCLE})_pcbias_${printf "%04d" $i}.nc  
     512$OUTDIR_ANALYSIS_RESTARTS/pcbias_$(printf "%04d" $i).nc 
     513}}} 
     514The CICE restart is also linked: 
     515{{{ 
     516ln -sf $CYLC_TASK_WORK_DIR/cice_restart.dat.$(rose date --use-task-cycle-time --offset=P1D --format='%Y-%m-%d')-00000  
     517$OUTDIR_ANALYSIS_RESTARTS/cice_restart.dat 
     518}}}
