DATES AND GUIDELINES

When applying for all GCS computing time allocations, applicants must follow the guidelines for how to apply and be mindful of deadlines for applications.

Dates

GCS Large-Scale Calls

Large-scale projects are characterised by projects that require a large amount of core hours over longer periods of time. For Large Scale projects' on the supercomputer SuperMUC-NG Phase 1 and SuperMUC-NG Phase 2, the following minimal requirements are given:

• >= 45 million core-hours on SuperMUC-NG Phase 1
• >= 140,000 GPU hours on SuperMUC-NG Phase 2

For Hunter at HLRS, the accounting unit is Hunter-node-hours. As a node contains four MI300A APUs, the lower limit for large scale projects is:

• >= 25,000 Hunter-node-hours on Hunter

For JUWELS Cluster the minimal requirements for GCS Large-Scale projects are specified in FLOP per year:

• >= 5250x1018 FLOP on JUWELS Cluster

FLOP refers to the peak performance. However, resources will be allocated and accounted in core-hours only.

It is possible to request computing time on both JUWELS Cluster and JUPITER Booster within the same application. However, the classification of an application as a Large-scale project is determined exclusively by the amount of compute time requested on JUWELS.

Large-scale projects go through a competitive review and resource allocation process established by the GCS. A "Call for Large-Scale Projects" is published by the Gauss Centre twice a year. Dates for closure of calls are usually at the end of winter and at the end of summer of each year. (more)

GCS Regular Calls

(A) Hunter and SuperMUC-NG Phase 1 and 2:
Applications for GCS regular projects on the HLRS and LRZ HPC systems can be submitted at any time (so-called rolling calls).

(B) JUPITER and JUWELS:
Applications for GCS regular projects on the JSC HPC system can be submitted twice a year at the same time as GCS large-scale projects (so-called cut-off calls).

Guidelines

The application procedures slightly differ for the three supercomputers and location sites. Therefore, please carefully read the following additional information on “How to Apply” for the individual GCS HPC systems:

General Requirements for project applications:

Applications should be submitted in English.

Please structure the project application in the following way:

  • Outline of the scientific challenge and your approach towards its solution (with references)
  • Description of previous work in this field, exploratory studies including the experience and results obtained (with references)
  • Statement of the scientific goals of the research project
  • Description of the physical and mathematical methods employed in the project, including numerical algorithms
  • Detailed schedule of the project, in the case of an extension of the project, please give details about any changes of your plans.
  • Preliminary studies that show good scaling behaviour of the programs under production conditions (i.e. typical parameter sets and problem sizes of the planned project, including I/O).
  • A detailed description of the I/O behaviour of the application (amount and size of files generated during typical runs, I/O strategy used (MPI I/O, netCDF, HDF5, SIONlib, etc.) and an estimate of the storage requirements during the project (scratch diskspace needed, amount of data which needs to be transferred during the project to and from the system).
  • If the project is a continuation of a previous project, please primarily describe how this project differs from the previous year's application. Please upload the previous application document as supplementary material.

  • Please follow the form “Project Proposal” (link below) for a project description with respect to form, content and size.
