Get a computing account¶
You may ask for a computing account at CC-IN2P3 if:
- you are an IN2P3 or IRFU staff member. Your request will need to be validated by your laboratory director;
- you work in collaboration with IN2P3 or IRFU staff members who are using CC-IN2P3 services and resources. Your request will need to be validated by the French experiment manager you work with, after acceptance by the IN2P3 management;
- you work on activities outside the IN2P3/IRFU scope but hosted by CC-IN2P3.
You should read the CNRS Information System Security Charter, then:
- fill in the application form and print the final PDF document;
- sign and have your responsibles (czar and lab director) sign the document;
- submit a request to user support attaching the scan of the signed document.
Your czar will inform you about the opening of your account. In the case you lose your password, your czar should be your first contact.

Definition of laboratory and group¶
Upon creation, a user account is associated with a laboratory and at least one group.
The laboratory is the hierarchical organization administratively responsible for the user. It is represented by the laboratory director and/or by the account czar. They sign the user account request form.
The group corresponds to an experiment or collaboration the user is working on; it is associated with the user account as a Unix group. The group manager is the request czar, who validates the access to the group resources. A user can therefore be associated with several groups, but with only one laboratory.
To know the default project associated with your user account (from an interactive server):
% qconf -suser <your account>
To know the principal group associated to your user account:
% id -gn
Without the option
–gn the command will list all the groups your account is associated with. To change your principal group, please refer to the FAQ.
