Gauss Call 27 (2022-1) for Large-Scale Projects on SuperMUC-NG (Call is open 2022-01-17 - 2022-02-14)

The Gauss Centre for Supercomputing (GCS) provides computing power and services of the highest performance class for computational sciences and engineering at its three member sites in Garching (Leibniz Supercomputing Centre, LRZ), Jülich (Jülich Supercomputing Centre, JSC), and Stuttgart (High Performance Computing Center Stuttgart, HLRS).

Projects are classified as “Large-Scale”, if they request 45 million core-hours or more per year on SuperMUC-NG. For these large-scale projects, a competitive review and resource allocation process is established by the GCS. Requests below this limit and requests for test projects will be directly processed by the individual member centres. A "Call for Large-Scale Projects" is published by GCS twice a year.

The current call 27 (2022-1) will be open

January 17th to February 14th 2022, 17:00 o’clock CEST (strict deadline).

The current call covers the period from May 1, 2022, to April 30, 2023.

Eligible for applications are members of German universities and publicly funded German research institutions, e.g., Max-Planck Society, and Helmholtz Association.

Applications for large-scale projects must be filed electronically via the GCS-JARDS form at

Please use the template files provided by GCS: to prepare your application.

Important: Change of Budget Policy for Project Extensions on SuperMUC-NG
Beginning with Call 24, the LRZ changed its policy regarding the extension of projects. Unused compute time budgets for GCS Large-Scale Projects will be cut off at the start of the new granting period. This applies equally, whether the project was a regular, or a large-scale project before. Alternatively, you may request a cost neutral prolongation of your project, to consume the remaining budget, but no new compute time will be awarded.

Example: A current GCS Large-Scale Project with 50 M core-h on SuperMUC-NG ends April 30, 2022, and has a remaining compute budget of 10 M core h. The PI writes an application for an extension of his GCS Large-Scale Project, asking for 75 M core-h for the next call period. The GCS steering committee grants 60 M core-h based on the reviews. May 1, 2022, the project starts with a budget of 60 M core-h. The remaining 10 M core h from the previous granting period could not be consumed in time and, therefore, are cut off.
