This tutorial session is meant to make you familiar with ETS workflow. This session is not targeting details of computations. It's rather view from broader perspective. I want to show you how to install Kepler, load ETS, learn basics of custom IMAS related actors.

Note that this part of tutorial is assumed to give you just an overview of all the components. We will not cover details here. It's supposed to give you the feeling of what is the target of this training and where we want to be after it is delivered.

ETS (the workflow) itself is a topic for a broader discussion.


1. Running ETS

In order to run ETS workflow you need few elements:

  • terminal with IMAS environment loaded (will be discussed later)
  • so called "dressed Kepler" - this is a dedicated version of Kepler with external actors (we will not cover it during this tutorial)
  • workflow file (XML based file that describes how workflow is organised) - we will not cover details of ETS during this tutorial

1.1. Preparing environment for ETS execution

In order to load ETS I will perform few steps:

  • load environment
  • install Kepler
  • start Kepler
  • load workflow

purge

Please note that in case you are not sure what environment is loaded you can always `purge` it

> module purge
> module load cineca

These two commands will bring you to the state with clean terminal session.

In order to install and run ETS based Kepler we have to run following commands

# Load IMAS environment - this will be discussed in other section
> module load imasenv

# Switch to Kepler release with all the ETS actors
> module switch kepler/2.5p4-3.0.4_dressed

# Install your own copy of Kepler
> kepler_install my_ETS_Kepler

# Load the version you have just installed
# - note that users/developers can work with multiple versions
# of Kepler at the same time (e.g. released, being developed, etc.)
> kepler_load my_ETS_Kepler

# Start Kepler
> kepler


2. Loading ETS workflow

TODO: describe how to load ETS

3. Kepler actors for IMAS

While analysing ETS workflow you will find lots of actors that are dedicated to IMAS itself. These actors perform (mostly) actions related to data input/output reading/writing. These actors are called Kepler Core Actors.

You can always refer to the list of all actors here: Kepler Core Actors

During this session we will briefly go over the list to give you the feeling of what each actor does.
