Applying for computing time

Scientists from RWTH Aachen and Forschungszentrum Jülich can apply for regular computing time projects on JURECA and/or CLAIX 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 will start on January 17, 2021.

Please note the following information 

Computing time on CLAIX:

RWTH Aachen University is in the process of restructuring the project categories. The new project categories will be announced soon. Within a JARA project, researchers can now request at most 8 million core hours on the CLAIX system summed across all JARA CLAIX resources (CPU nodes, Large Memory nodes, and GPU nodes). For larger needs on CLAIX please refer to the information provided here.


Computing time on JURECA:

Phase 2 of the JURECA‐DC (data centric) module is now in operation at JSC and 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.
