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 homepage. Follow the link “Création d’un compte ou connexion sur eDARI” to create/access your private space in order to:
    • Provide information about a dynamic access file which will be examined by the IDRIS director, or by experts in the related scientific field if the request is for a large number of hours.
    • Fill in the on-line computing account form if you do not have an account on Jean Zay.
  • If you already have an account on Jean Zay, you may request that this dynamic access project be joined to your account by completing the first section of the IDRIS FGC form, “Multiproject logins: Add a project”.
  • 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 :

  • Supplementary resources as needed (“demandes au fil de l'eau”) for existing projects which have used up their hours quotas during the year (AI dynamic access and HPC regular access).
  • 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 is:
    • 50 000 core hours on the Jean Zay CPU partition
    • 1000 GPU hours on the Jean Zay GPU partition
