Calls for Computing Time Applications

The following synchronized calls for computing time applications were published on 20 July 2020. The strict deadline for submission of proposals for all calls is 17 August 2020, 5pm CEST. An overview of all calls can be found at

The Gauss Centre for Supercomputing (GCS) has issued the 24th call for Large-Scale Projects. Researchers at German universities and publicly funded research institutions are eligible to apply. Projects are classified as “Large-Scale” if they require at least 2 % of the systems’ annual production in terms of estimated availability. Available systems include the supercomputers HAWK at HLRS, SuperMUC-NG at LRZ, and JUWELS at JSC. Within this call, projects can apply for resources on the new JUWELS Booster Module for the first time.

Researchers at German universities and publicly funded research institutions can also apply for GCS/NIC Regular Projects on the JUWELS Cluster and Booster as well as on the JURECA Booster. As of now, scientists from Forschungszentrum Jülich and the RWTH Aachen University are also eligible to submit proposals for GCS/NIC Regular Projects. However, computing time on the JURECA Booster is only available via JARA/VSR (see below). For further information on GCS Large-Scale and GCS/NIC Regular projects, please visit

Researchers from all HGF institutions in the research field Earth and Environment together with national cooperation partners outside the HGF may apply for resources on the ESM partition of the JUWELS Cluster and Booster. Please visit for details.

Finally, researchers from RWTH Aachen University and from Forschungszentrum Jülich can submit applications for computing time on the JARA Partition and for VSR projects. Resources on the CLAIX system located in Aachen and on the JURECA Booster Module at JSC are available through JARA. Jülich scientists can additionally apply for resources on the new JURECA DC Module. Further information is available at

To account for the fact that the effective computing power per core hour differs for different modules and resources, computing time requirements expressed in units of Mcore-h for each requested resource are converted to floating point operations in units of exaFLOP (EFLOP) based on the corresponding theoretical peak performance. Further details on this conversion can be found at
