The DARI help page:


Users of the national computing centres (CINES, IDRIS,TGCC) may submit requests for resources (for new projects or project renewals) once per year during a DARI “call for projects”. These calls take place 2 times per year and result in allocations of hours which are valuable for one year (except for A1 and A2 allocations). Each request must be submitted in the form of an electronique file which contains an administrative part and a scientific part which is composed essentially of accompanying documentation (PDF format obligatory). The file may be enregistered by any person associated with the project (not necesssarily by the scientific project manager). However, this person must have previously created an account on the DARI site in order to log in.

The important steps in creating and submitting a file are as follows:


This first step, the administrative part of the file (“Administrative du dossier”), is relatively rapid, especially if you are already a user and you are renewing an existing project. We advise you to provide the requested information precisely and thoroughly as this will help the experts who will study your request. You will see that there is very little mandatory information required. However, it is imperative to begin filling in each of the mandatory sections (even if you can later come back and make modifications in these sections by using the “modification du dossier” mode). The mandatory sections are indicated on the form by a red dot. You must begin ALL of the mandatory sections (!) before enregistering your file or you will lose all the information you have entered as the program does not indicate the uncompleted sections until you have enregistered your information: “Enregistrer”.


As we have indicated above, you do not need to entirely complete the form at the beginning. You can simply begin with the mandatory sections and then enregister the information so that your file is created. Then, by using the consultation and modification functions, you may complete, correct or modify your file at your own rhythm.


Parallel to the administrative part of the application, you must complete the scientific part and submit all the documents which describe your research project. These documents may be contained in only one file or in several files. The contents must include 3 parts:

  • A summary
  • A list of publications (optional here as this must be contained in the administrative form)
  • A general presentation and the method employed

In the case of a project renewal, a report of the activity of the project file you wish to be renewed must also be furnished by using the corresponding section of the user menu. All of the submitted documents must be in PDF format to facilitate access by experts who will study your file.


This step is very important. It is not until you have validated your file that your request is complete and can be transmitted to the committee of experts who will study it. Nevertheless, do not validate your file if it has not yet been finished. In principle, once you have validated (“validé”) your file, you cannot modify it. However, if it is necessary, a means can be given to you to undo the validation (“dévalidé”).


After your file has been validated, you need to display the first page (the administrative part) on the screen and then print it. This page must be signed by both the scientific project manager and the laboratory director. You then need to scan this signed document and enregister it on your work station with the name visa.pdf, followed by uploading it onto the DARI site. After uploading it, this document will automatically be integrated into your file with the supporting documents (“Documents annexes”). If you do not have the possibility of scanning the visa document, you can send it by postal mail or by fax to the concerned computing centre(s). It is imperative that the “visa” be integrated into your file before the committee attribution date of the relevant project call.

IMPORTANT : In the absence of the “visa”, your project will not be opened on the computing machines.


Beginning with the A2 call allocations, you have the possibility of requesting complementary resources halfway through the time period for an existing project. This request necessarily concerns a DARI file created for the preceding project call. You must indicate at which centre(s), on which machine(s), and the number of complementary hours you would like for the 6 remaining months of your allocation. You must justify this request in a document which should be uploaded onto the DARI site.


Throughout the year, users who reach their quota of allocated hours may submit a request for supplementary hours (“demande au fil de l'eau”). The quantity of hours requested must necessarily be limited. Once the request is submitted on the site, it is automatically transmitted to the director of the concerned centre who can then transmit it to the President of the corresponding thematic committee for arbitration. The result of this request is then communicated to the project manager by e-mail.


Outside of the regular DARI allocations, users or future users of the national computing centres have the possibility of submitting a request for preparatory access (“accès préparatoire”). This procedure was inspired by the PRACE “Preparatory Access” system. These requests, if accepted, permit the project users to test or optimise their codes on a targeted machine. These hours allocations are fixed and limited. The request is examined by the director of the concerned centre who can transmit it to the president of the corresponding thematic committee. The result of the request is then communicated to the project manager by e-mail.

Users are requested to insert one of the following mandatory acknowlegements into scientific publications concerning jobs which benefited from an allocation of resources. The purpose of this is to improve the visibility of the national means of intensive computing available to the scientific community.
