Applying for computing time

Scientists from RWTH Aachen and Forschungszentrum Jülich can apply for regular computing time projects on JURECA, CLAIX and now also on a D-Wave Advantage™ quantum system twice a year in January/February and July/August. Successful projects start May 1st and November 1st and have a duration of one year (project extensions are possible).

The application process for the next computing time period starts on January 17, 2022 and ends on February 14, 2022, 5pm CET (strict deadline).

Please note the following information 

Computing time on CLAIX:

Within a JARA project, researchers can request between 2.4 and 8 million core hours on the CLAIX system. For smaller or larger needs on CLAIX please refer to the information provided here.


Computing time on JURECA:

The JURECA‐DC (data centric) Module is available mainly for scientists from the FZJ campus. However, researchers of the RWTH Aachen university can also apply for resources on JURECA‐DC CPUs and/or GPUs within JARA, if they benefit from the Modular Supercomputing Architecture (MSA) of the system. Requirements for this are:  

  • A need for at least two resources/modules is required, i.e., either JURECA‐DC CPUs together with JURECA‐DC GPUs or JURECA‐DC CPUs together with the JURECA Booster Module.
  • Either heterogeneous applications have to be used, where, for example, different parts of a simulation code use different physical models and run therefore on different resources/modules. Or heterogeneous work‐flows are deployed, for example, to model phenomena on different length scales or to perform chains of simulation and data analysis parts, where the different parts run on different resources/modules.
  • The modularity of applications and/or work‐flows must be clearly described in the application form.


Important information for requests on the JURECA Booster Module: Please note that this is the last time computing time resources will be offered for the JURECA Booster Module, as it will be shut down and dismantled by autumn 2022. Therefore, this resource will only be available for 6 months. The computing time will be allocated for the period from May to August 2022. For September and October, the operation of the system cannot be guaranteed. Unused computing time cannot be transferred to other resources. Other supercomputer systems offered in this call are not affected by this regulation.
