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.

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

> module purge
> module load cineca

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
