This page provides a summary of examples and tools designed to help you get used with the Irene Rome environment.
How to access the cluster
For people on the "Atmosphères Planétaires" GENCI project who need to open an account on Irene-Rome, here is the procedure:
- Log on to https://www-dcc.extra.cea.fr/CCFR/ and provide various information about yourself
(chose TGCC ; Note that they seem quite picky on having your PROFESSIONAL phone number; your personal cell phone number won't do, you must give your office phone number) and the project: Nom du projet: Atmosphères Planétaires Numéro du Dossier: A0120110391 Responsable scientifique du projet: M.
