Access to JURECA

Access to JURECA is available through different calls that all have different eligibility criteria and resources to be distributed:

  • VSR/JARA-HPC (Jülich Aachen Research Alliance)
  • NIC (John von Neumann Institute for Computing)
Resource pool Resources Eligibility
VSR/JARA-HPC 37 million core hours* Researches affiliated with Forschungszentrum Jülich and/or RWTH Aachen;
national and international collaborators possible
NIC 70 million core hours* German researchers;
national and international collaborators possible
*Numbers from end of 2015

The calls for all resource pools are synchronized:

  • Two calls per year
  • Calls open end of January and end of July for about one month
  • Allocation periods start 1 May and 1 November every year
  • Computing time is granted for one year, extension of projects is possible after each year
  • Selection of projects is based on a peer-reviewed process

Applications are accepted online only, not via email or regular mail:


Information to provide in computing time proposal (excerpt):

  • Clear scientific goals, verifiable milestones
  • Detailed and clearly arranged work schedule
  • Well-founded and detailed demonstration of required resources
  • Preliminary studies demonstrating good scaling behavior to at least 8192 cores under production conditions
  • Status report (in case of a project extension)

Examplary computing time proposals:


JSC also provides preparatory access to its supercomputer resources. Approved preparatory access projects get about 5,000 core hours on JURECA supplemented by expert assistance from one of the JSC SimLabs for a period of up to four months to verify and improve the performance of their application and prepare a full computing-time proposal. Expertise offered by SimLab staff includes:

  • Porting and tuning of codes for the JURECA and JUQUEEN systems
  • Performance analysis and scaling improvement of codes/applications
  • (Re)design of computational methods needed to exploit highly parallel architectures

SimLab Neuroscience is in place to provide this kind of support to neuroscience projects:
