How to file a compute time application

How to file a compute time application


Three steps are required in order to successfully file an application for compute time for research purposes:

  1. Provide a description of the project
    1. A concise project description should be formulated for small research projects (1-2 pages).
    2. For larger compute projects a detailed project description similar to the one described in Guidelines for proposals for computing time on the JARA partition is required.
      Should your project be related to a peer-reviewed and approved research project (DFG, BMBF, EU or alike), please add to your project description the corresponding note of approval in order to reduce the effort for the scientific assessment. 
      We ask you to provide your project description in English. As an exception, we are ready to accept project descriptions in German under the condition that you provide an English version in case this is requested by the reviewers.
  2. Next, fill out the JARDS online form providing your resource requirements necessary for the technical assessment. In many cases it is just the sheer compute capacity that is the limiting factor. The form asks for information not only about the resource requirements in CPU-hours, but also about the parallel processing, the memory, storage and software requirements, and others of that kind.
    The amount of disk space which is provided by default is150 GB, 250 GB, and 1 TB on the HOME, WORK, and HPC_WORK file systems respectively.
    Furthermore, you are prompted to classify your field of research according to the DFG’s subject classification system of the years 2016-2019. For continuity reasons we still adhere to the older list of scientific subjects.
    We depend on your information in order to provide an optimal environment concerning hard- and software for your immediate work. We also need to have a good knowledge of your needs in order to be able to shape the future of the RWTH compute cluster.
  3. JARDS generates a PDF file which will be sent to you by email once you finalize the online submission.
    NEW: If the PI uses a trusted email address (fz-juelich or rwth-aachen domain) the submission can be finalized by the PI online (without paper).
    Otherwise print out this PDF file. It has to be signed by the principal investigator and then sent to us:
    1. by eMail to, using this subject: "Application for Compute Time No. NNNN"
    2. by (paper) mail to
          RWTH Aachen University, IT Center,
          Seffenter Weg 23, 52074 Aachen
    3. or by fax to
          (+49) (0241) 80-22134    (please check fax transmission status!)

More than one scientist can participate in these projects, in which case the resources granted will be available for collective use by the project members. In fact, in order to reduce the complexity while processing the proposals, we would kindly ask you to define meaningful project sizes and if possible combine your requests instead of having each scientific employee submit his or her own application.

Applications for compute time for courses and thesis works follow a similar path, but instead of project description you only need to provide the title of the course/seminar/practica, respectively the title of the thesis work and information about the graduate.

Here you can find an example of a PDF file generated by JARDS, and here a template of a project description for projects, which have to be reviewed.

For compute time applications for a large computing project you can use the detailed JARA application template.
