Please submit the complete project proposal for a compute project to the HLRN service portal. A proposal contains the four documents Stammdaten, Projektbeschreibung, Kurzbeschreibung, and a signed letter (please see details below).

After submission the proposal is evaluated in a review process organized by the HLRN Scientific Board. Each reviewer obtains access to

  • the project proposal,

  • the history of previous projects,

  • contact data of the HLRN consultant, and
  • aggregated statistics for NPL usage on the HLRN systems.

Stammdaten / meta data (Online)

During the course of online submission the project proposer needs to address meta data on the HLRN service portal. This includes information about

  • the principal investigator (scientist holding a PhD),
  • the person in charge submitting the proposal,
  • project partners,
  • other evaluations and fundings for the project
  • usage of other compute resources,
  • project lifetime,
  • software requirements (please check availability with your consultant before),
  • compute time requirements, and
  • storage requirements.

Projektbeschreibung / main proposal text (PDF)

The proposal needs be to upload a prepared document in PDF format, the "Projektbeschreibung".

The proposal is written in English or German and should contain about 10 pages.

This documents includes the main scientific content of the proposal and might be aligned to the following structure.

  • Abstract (about 0.5 pages)
  1. Project description
    1. Problem description and aims of the project
    2. Scientific significance, innvation, expected results, utilization of results (about 1-2 pages for a.+b.)
    3. Mathematical modeling used
    4. Technology and tools for numerical solution (about 1-2 pages for c.+d.)

    5. Preliminary studies/results of the preceding project (about 2-3 pages)

    6. Descriptions of research plan and work packages (about 1-1.5 pages)
  2. Computational facets
    1. Software, libraries, licences, target architecture (a list)
    2. Necessity of parallel computing hardware (about 0.5 pages)
    3. Concept for parallelization, scaling properties, application performance (about 1.5 pages)
      1. Parallel efficiency, strong/weak scaling
      2. Performance properties, precondition for estimations in the resource plan
      3. Necessity of HLRN resource, larger than e.g. university
  3. Resource estimation
    1. Detailed plan for compute time and NPL (see Accounting and NPL), work plan (1-1.5 pages)
    2. Storage demands, scaling properties for I/O
  4. Literature
  5. Appendix
    1. Funding decisions
    2. Publication list
To avoid:
  • Imprecise or incomprehensible estimation of requested computational resources (especially NPL/core-hours); for example missing arguments to justify a certain number of N runs instead of a smaller number. One page is our recommended minimum.
  • No proof, that the software to be used is suitable and efficient for parallel execution (and parallel I/O) on our specific supercomputer. Recycling a scalability demo by a third party is meaningless, without showing that your planned production run is fully comparable to it (algorithm selection within the software, I/O pattern, machine architecture, problem size per core).
  • The overall aim and/or motivation behind the project is unclear.
  • The applicant lacks HPC/Unix skills and an experienced co-applicant is missing.
  • Insufficiency of the applicant's local resources is not indicated.
  • The HLRN was not mentioned in relevant publications.
  • Cut & paste of previous proposals.

In case of questions regarding the required documents please contact your HLRN consultant.

Kurzbeschreibung / abstract (PDF)

All present HLRN projects that have been successfully reviewed by the Scientific Board are listed on the HLRN project list. Each proposal for a compute project needs to submit a Kurzbeschreibung / project abstract in PDF format based on the HLRN abstract template.

The abstract is written in English or in German and should contain about 2 pages.


Signed letter (by email)

By the end of the online submission an email is created by the HLRN service portal. The project proposer is requested to print and sign the document and finally to send it to the Office of the Scientific Board.
