Developing a projectΒΆ

Autosubmit is used at BSC to run EC-Earth. To do that, a git repository has been created that contains the model source code and the scripts used to run the tasks.

EC-Earth experiment

36 Example of monitoring plot for EC-Earth run with Autosubmit for 1 start date, 1 member and 3 chunks.

The workflow is defined using seven job types, as shown in the figure above. These job types are:

  • Local_setup: prepares a patch for model changes and copies it to HPC.
  • Remote_setup: creates a model copy and applies the patch to it.
  • Ini: prepares model to start the simulation of one member.
  • Sim: runs a simulation chunk (usually 1 to 3 months).
  • Post: post-process outputs for one simulation chunk.
  • Clean: removes unnecessary outputs from the simulated chunk.
  • Transfer: transfers post-processed outputs to definitive storage.

Since Autosubmit 2.2 the user can select the desired source repository for the experiment project and using a given concrete branch is possible. This introduce a better version control system for project and more options to create new experiments based on different developments by the user. The different projects contain the shell script to run, for each job type (local setup, remote setup, ini, sim, post, clean and transfer) that are platform independent. Additionally the user can modify the sources under proj folder. The executable scripts are created at runtime so the modifications on the sources can be done on the fly.


Autosubmit automatically adds small shell script code blocks in the header and the tailer of your scripts, to control the workflow. Please, remove any exit command in the end of your scripts, e.g. exit 0.
