How to run a simple test case with ORCHIDEE offline with a batch job

First prepare a run directory following the how to How to run a simple test case with ORCHIDEE.

Then prepare a job according to computer environement and the choice of parallelization and submit it.

curie/TGCC

MPI mode

• First prepare a run directory following the how to How to run a simple test case with ORCHIDEE. But instead of using wget to copy the files, they can be found in the directory /ccc/work/cont003/dsm/p86ipsl/IGCM and can be linked or copied directly. The path is the same.

• Then create a text file as follow and save it as Job_curie :

  #!/bin/ksh
  ######################
  ## CURIE   TGCC/CEA ##
  ######################
  #MSUB -r test             # name of the job
  #MSUB -o Script_Output    # name of output file for standard messages
  #MSUB -e Script_Output    # name of output file for error messages
  #MSUB -eo
  #MSUB -n 4                # Request numbre of cores
  #MSUB -T 1800             # Time limit in seconds
  #MSUB -Q test             # Queue test, priority acces
  #MSUB -q standard
  #MSUB -A gen6328          # Set your project id
  BATCH_NUM_PROC_TOT=$BRIDGE_MSUB_NPROC
  set +x
  
  cd ${BRIDGE_MSUB_PWD}
  /usr/bin/time ccc_mprun -n 4 ./orchidee_ol
  

• Submit the job :

ccc_msub Job_curie

• Survey the job while it is still in queue :

ccc_mstat -u

• Kill the job if needed, take the jobid from the ccc_mstat command :

ccc_mdel jobid

Hybbrid MPI/OpenMP mode

Note that the hybrid mode is only for the coupled mode with lmdz.

#MSUB -c 2                    # Number of threads per task to use (OMP)
#MSUB -N 4                    # Number of nodes  = 32*2/16 = 4
#MSUB -T 1800                 # Elapsed time limit in seconds 
#MSUB -q standard             # Choosing thin nodes

#MSUB -o Script_output        # Standard output

• Submit the job :

  llsubmit Job
  

• Survey the job while it is still in queue :

  llq | grep login
  

• Kill the job if needed, take the jobid from the llq command :

  llcancel jobid
