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-atoshpc2020)
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.

prep-ic-icmcl-compo.sh - a script to generate initial conditions for chemical fields for the selected run time. Begin and end date need to be given as an argument.
config.h - settings for model installation, paths, and experiment configuration.
oifs-run.sh - this script controls the workflow for the experiment: reads experiment config, sets up run directories (in $SCRATCH), loads platform configuration, edits namelists, links to initial conditions and executes OIFS_RUNCMD
ecmwf-atoshpc2020.job wrapper script for oifs-run.sh, required settings for the batch scheduler

...

it is necessary to create a platform-specific machine config file: oifs-config.ecmwf-atoshpc2020.sh

The above ecmwf-atoshpcs2020.job wrapper script to submit the batch job is based on templates in the platform directory; a number of templates exist and for the ECMWF HPCF the following templates are relevant:
