• Easybuild is installed and publicly available via module system
• Your Easybuild configuration file exists and is properly configured
• IMAS related receipts are downloaded from all repositories their sources being used

• All modules are purged and EasyBuild module is the only module loaded:

  Code Block
  module purge module load EasyBuild

• $EASYCONFIG_PATHS system variable is set to point to all directories with easyconfig files 
• Your TMP  directory is set up to use $ITMWORK

Easyconfigs

Sources of the receipts (aka 'easyconfig' files):

• EasyBuild built-in receipts
• EasyBuild receipts repository
• Gateway specific receipts
• 'Limbo' of the IMAS receipts
• ITER repository of the IMAS receipts 

Downloading configuration (EB) files

...

rsync -av --delete -e "ssh -J <user>@sdcc-login.iter.org"  <user>@sdcc-login02.iter.org:/work/imas/opt/EasyBuild/ebfiles_repo/ ./all_iter/

Clone these repositories and  specify the paths to them in the --robot  in the next step.

export EASYCONFIGS_PATH=`pwd`/all_iter

To enable dependency resolution, use the --robot command line option (or -r for short):

Preparing easyconfig files

To allow the users to seamlessly switch between EUROfusion and ITER clusters the environment that is built on the Gateway mimics (to some extent) the one of the ITER SDCC machines. 

To achieve this a receipts from the ITER cluster are utilised to install software on the GW.

This simple mechanism will be replaced with a more complex one, where receipts would be maintained in GIT repositories.

Downloading configuration (EB) files

Source SDCC: /work/imas/opt/EasyBuild/ebfiles_repo/ 

rsync -av --delete -e "ssh -J <user>@sdcc-login.iter.org"  <user>@sdcc-login02.iter.org:/work/imas/opt/EasyBuild/ebfiles_repo/ ./iter-receipts/

Set system variable EASYCONFIGS_PATH  that points to the directory with receipts

export EASYCONFIGS_PATH=`pwd`/iter-receipts

Searching for receipts

EasyBuild needs a receipt to install any software component. The following command can be used to look for receipts:

eb --search <software_name> --robot-paths=$EASYCONFIG_PATHS

A <software_name>  could be only part of the name being searched. Additionally EasyBuild search is case insensitive. E.g. "dox"  string can be provided while looking for "Doxygen" 

...

eb <receipt name>.eb --allow-modules-tool-mismatch --robot=$EASYCONFIG_PATHS

e.g.:
eb IMAS-AL-Cpp-5.2.0dev-foss-2020b-DD-3.40.1.eb --allow-modules-tool-mismatch --robot --robot-paths=$EASYCONFIGS_PATHS
