Depending on the available hardware experiments can either be run interactively or as a batch job.
In order to run the experiment interactively run ./oifs-run in your terminal. If no command line parameters are provided with the oifs-run command, then the values from the config.h will be used.
...
Alternatively, a job script could be used for submitting the script to the batch scheduler. An example script for the SLURM batch schedule, used on the ECMWF hpc2020 is provided here: $OIFS_HOME/bin/run.atos.sh
This script should be edited as required. The LAUNCH command here is only "srun" without any further options, as the parallel environment settings are provided through the script headers.

This requires the use of Jupyter Notebooks using a conda environment with Metview and Metview-Python libraries. On the ECMWF hpc2020 the Jupyter server a Jupyterlab session can be started using the command |
Copy the Metview processing code to your $PERM location:
...
- On the ECMWF Virtual Desktop Interface (VDI) open a terminal, log into the hpc2020 with command:
ssh hpc-login - In the terminal start the Jupyter server on an interactive node, using the command:
ecinteractive -k - After the interactive node has started you will be given a weblink to connect to Jupyterthe Jupyterlab session.
- Open the Chrome browser on the VDI and paste the weblink into the address field; this will connect to the Jupyter server.
- Find $PERM/mv/ipynb/single.ipynb in the browser, open the Notebook and run all cells of the Notebook.
