On the ECMWF hpc2020 our model has been previously installed to $OIFS_HOME
which is in $HOME/openifs-48r1
. 1. For the experiment we extract the ab2a package to to $OIFS_EXPT
which is in a different location on the file system. The experiment directory shall therefore be $OIFS_EXPT/ab2a/2016092500
.

- It is important to change
"/path/to/your/config/oifs-config.edit_me.sh"
to the actual path for theoifs-config.edit_me.sh,
e.g.,"$HOME/openifs-48r1.1/oifs-config.edit_me.sh"
- The default resources requested in
run.ecmwf-hpc2020.job
are 8 nodes on the ECMWF hpc2020 machine, with a total of 256 MPI tasks and 4 OpenMP threads. This can be changed as required. - For information, the
LAUNCH
command for batch job submission is set to "srun
" without any further options, because all required parallel environment settings are provided through the SLURM script headers.
