This tutorial shows how to install IMAS (after repository split) using EasyBuild. The installation in this tutorial will be performed on the Gateway cluster but it can be done anywhere.

Install EasyBuild

You should install EasyBuild using Python and venv (virtual environment).

...

You can use a different version of Python. Remember to purge all unnecessary modules that can cause conflicts with new modules created by EasyBuild.

ConfiguringEasyBuild

To enable access to ITER GIT repositories HTTP access token is required.

• Go to ITER  Bitbucket (https://git.iter.org).
• "Manage Account" - press user icon (upper right corner)
• "Http Access Token"
• "Create Token"
• Copy token to clipboard
• Create a secret.txt  file in $HOME/.config/easybuild/ and paste the access token there

Authorization: Bearer <token>

The configuration is located in the file file $HOME/.config/easybuild/config.cfg. Create this file if it doesn't exist.

# System variables cannot be used in EB config file!!! 
# Do not put string values in quotes !!! 

[config]
prefix=/pfs/work/g2pbloch/imasenv_eb
modules-tool=EnvironmentModulesC
module-syntax=Tcl
[override]

• Clone repo with easyconfigs: `https://gitlab.eufus.psnc.pl/g2pbloch/ebfiles_repo
• Replace the paths to your python installed by easybuild in the files: /IMAS-AL-Core/IMAS-AL-Core-5.3.0-foss-2023b.eb, /IMAS-AL-Core/IMAS-AL-Core-5.3.0-intel-2023b.eb ,  /IMAS-AL-Python/IMAS-AL-Python-5.3.0-foss-2023b-DD-3.42.0.eb ,`/IMAS-AL-Python/IMAS-AL-Python-5.3.0-intel-2023b-DD-3.42.0.eb`
•  Run installation:
