1. Conteneurs
singularity vs docker
gestion container dans Concordia
-> job container en tant qu'objet Dirac
CTA : utilisation containers surtout pour les services => thème différent mais intéressant !
mais pas forcément pour les applications (pb Corsika optimisé ne tournent pas dans un conteneur)
biomed : initialement singularity, maintenant udocker -> marche bien sur EGI
déploiement software sur cvmfs puis script qui lance le conteneur en lisant les fichiers sur cvmfs
2. Discussion et tests des Tokens, IAM vs CheckIn - Andrei
3. Production System via yaml configuration - Alice
