Requesting resource hours at IDRIS

Requesting resource hours on Jean Zay is done via the DARI site www.edari.fr, common to the three national computing centres: CINES, IDRIS and TGCC.

The procedure to follow differs depending on your usage objectives :

  • To develop algorithms in Artificial Intelligence (AI) on the Jean Zay GPU partition, or
  • To effectuate high performance computations (HPC) on the CPU and GPU partitions of Jean Zay

Before requesting any hours, we recommend that you consult the GENCI communication (in French) detailing the conditions and eligibility criteria for obtaining computing hours.

What is your usage objective?

To develop algorithms in Artificial Intelligence (AI) on the Jean Zay GPU partition

  • This usage is intended for researchers wishing to develop algorithms, methodologies or tools (machine learning and deep learning) in Artificial Intelligence.
  • To request computing hours for this type of activity, consult the section, “Développer des algorithmes en Intelligence Artificielle (IA)” on the DARI Website. The link “Mon espace” allows you to create/access to your private space in order to:
    • Complete a dynamic access file which will be examined by the IDRIS director, or by experts of the related scientific field if the request is for a large number of hours.
    • Renew a dynamic access file when it expires after one year if you wish.
    • Complete the on-line computing account form if you do not have an account on Jean Zay.
    • Request the linking of your account to a new dynamic access file.
  • You can find IDRIS documentation to help you complete each of these formalities via the DARI portal.
  • The hours allocation is valid for a period of one year after the opening of a computing account on the Jean Zay GPU partition. Requests for hours may be made throughout the year.

  • An explanatory video (in French) is available below:

High Performance Computing (HPC) on the Jean Zay CPU and GPU partitions:

  • This usage is intended for researchers doing modelisation and numerical simulation for resolving complex computing problems.
  • Two project calls for regular access are launched each year:
    • In January-February for an hours allocation from 1 May of the same year until 30 April of the following year,
    • In June-July for an hours allocation from 1 November of the current year until 31 October of the following year.
  • To request computing hours during these project calls, consult the DARI site, section “Calcul haute performance (HPC) et utilisation IA”. Follow the link, “Création d’un compte ou connexion sur eDARI” to create/access your private space in order to:
    • Provide information for a regular access file which will be examined by experts, or
    • Renew a regular access file which will be examined by experts, or
    • Migrate from preparatory access (see section below) to regular access, which will be examined by experts.
  • To request the opening of an account, consult the IDRIS document on Account management.

Other resource requests:

Throughout the entire year you may request the following resources on the DARI site www.edari.fr :

  • Preparatory access (“accès préparatoire”): This type of request was introduced to assist in the porting, optimisation and parallelization of HPC compute codes on CPU and/or GPU for the preparation of a regular access file. The requests will be examined by IDRIS which, if needed, will seek advice from the president of the Thematic Committee related to the project. The quota of hours which could be allocated for a period of 6 months is:
    • 50 000 core hours on the Jean Zay CPU partition
    • 1000 GPU hours on the Jean Zay GPU partition
  • Supplementary resources as needed (“demandes au fil de l'eau”) for all existing projects (dynamic access, HPC regular access, and preparatory access) which have used up their hours quotas during the year.
