Account management: opening and closure of accounts

Opening a user account

After a project has been approved and obtained hours on one of the IDRIS computers, it is given an identifying “project number”.
Each user in the project must individually request the opening of his/her account: There is no automatic or implicit account opening.

For a new project

Each individual person wishing to open a project account at IDRIS must complete the GENCI Account Creation Request form, whether or not he/she already has an account at IDRIS: link (Choose English language version on the GENCI page.).

Attention: In application of the regulatory measures for the protection of the national scientific and technical potential (PPST), the creation of a new account may require a French ministerial (MESR) authorization. The decision about whether to pursue this authorization is made by the IDRIS Director or the CNRS Defence and Security Officer. Considering that the authorization processing period at the ministry may take up to two months, a personal communication will be transmitted to the project manager and the concerned user(s) in order to begin implementation of the required procedure.

For a project renewal

Accounts already existing on the previously accessible compute machines are automatically carried over from one allocation session (project call) to another, if the eligibility conditions of the project members have not changed (cf. GENCI explanatory document "Attribution d'heures de calcul", section 3. “Conditions d’éligibilité”).

  • If your account is open and the project is granted hours in the following project call on the same compute machines as in the preceding project call, no action on your part is necessary.
  • If the renewed project is granted hours on a compute machine to which the project was NOT given access during the preceding allocation, ALL the users of this project must request the opening of an account on this new machine by using the FGC form (section: “Extension of a user account to a supplementary machine”).
  • You may make necessary modifications on an existing account (addition/removal of IP addresses or changes in postal address, phone number, employer, etc.) by using the FGC form.

How to transmit forms to IDRIS

All forms must be transmitted to IDRIS by e-mail to the following address: .

Closure of a user account

An account can only exist as “open” or “closed”:

  • Open. In this case, it is possible to:
    • Submit pre- and post-processing jobs on Adapp.
    • Submit bonus jobs on the compute machines if the project still has bonus hours remaining (cf. the last lines of the 'cpt' command output).
    • Submit jobs on the compute machines if the project's current hours allocation has not been exhausted (cf. 'cpt' command output).
  • Closed. In this case, the user can no longer connect. An e-mail notification is sent to the project manager and to the user at the time of account closure.

Attention: After an account is closed, the files can be deleted at any time by IDRIS.

Account closure per request of the project manager

A project manager may use the FGC form to request an account closure.
It is the responsibility of the project manager to close the account of a project member who is no longer working on the subject matter of the project or who, having changed employer, is no longer paid by a French research organisation (cf. GENCI Attribution d'heures de calcul, section 3: “Conditions d’éligibilité”).


  • The request for an account closure concerns all the machines for which this account was opened.
  • Account closure will result in the destruction of all the account files at the initiative of IDRIS after an undefined time delay.
  • Only the project manager may request the copying of these files to another account (to be requested via the FGC form). It is indispensable, in this case, to verify that the available space is sufficient for the copied files (project disk quotas on the servers).
  • Whether the files are copied to another account or not, only the project manager may request that the account files be immediately destroyed during the account closure in order to, for example, liberate the disk quotas (request “immediate purge” on the FGC form).

Account closure by IDRIS

Account closure of an unrenewed project

When a GENCI project is not renewed, the following procedure is applied (regardless of the project's lifespan):

  • On the date of project expiry, DARI and bonus hours are no longer available and the project accounts can no longer submit jobs on the compute machines (except for Adapp). However, the project accounts remain open for a period of six months.
  • After this six-month delay period, all the project accounts on all the servers are closed.

File recovery, by transferring files to a local laboratory machine, is the responsibility of each user during the six months following the end of an unrenewed project.

This six-month delay period allows avoiding the premature closing of project accounts: This is the case for a project of allocation Ai which was not renewed for the following year (allocation Ai+2) due to not needing more calculation hours at the end of period Ai but which is renewed for the allocation Ai+3 (which begins at the end of the six-month period).

Account closure following expiry of the ministerial access authorisation for IDRIS computer resources

The first notification of impending expiry is sent out 90 days before the expiry date and a second, 70 days before the expiry; the account is then closed on the expiry date. To avoid this account closure, the user is advised to submit to IDRIS a new GENCI Account creation request form link (Choose English version on the GENCI page) as soon as receiving the first notification so that IDRIS may begin processing an access prolongation request.

Account closure for security reasons

An account may be closed at any moment by decision of the IDRIS management.
