  • To do this we run the standard t21test for experiment epc8 (T21L19) with the setup-exp.sh new script.
  • The name for the hardware platform needs to be set (l.89, e.g. platform=ecmwf-atos)
  • The test experiment runs in the RUNDIR directory specified in setup-exp.sh (l.94, the default is $SCRATCH/43r3/epc8/).
  • We also need to use the command line option -x and give as argument the absolute full path to the master.exe binary executable.
  • In setup-exp.sh you should change the value for RUN_NUMBER otherwise any pre-existing model output from this test will be overwritten. 

...

Test result:  As before an error calculation file res_021_0072 is created in the run directory and the model output is found in the subfolder output1 (this name depends on the RUN_NUMBER variable). 

Info

Running on the ECMWF HPCF: 
This script requires more resources than are provided using the ecinteractive node.
One recommendation is to adapt an existing template from the platform subdirectory and submit this using the sbatch command.
Alternatively, the srun command could be used:
export NPROC=120 
export OMP_NUM_THREADS=4 
export OIFS_RUNCMD="srun --qos=np $OMP_NUM_THREADS -n $NPROC master.exe" 
./setup-exp.sh -n 120 -t 4 -x master.exe 


With chemistry:  Now repeat the test with enabled model chemistry. This is a short 1-day test run that uses the newly added source code of OpenIFS/AC. It has a very limited set of options and should not be used for forecast experiments. Note that you cannot increase the experiment duration beyond one day because the boundary conditions are only supplied from 2013-07-01 to 2013-07-03.
