24th Call for Large-Scale Projects Open
Newsflash 10/2020 –

Today, the Gauss Centre for Supercomputing (GCS) opened the 24th call for GCS Large-Scale Projects on the three GCS high-performance computing (HPC) systems, Hawk of HLRS, JUWELS of JSC, and SuperMUC-NG of LRZ. Scientists can now apply for computing time until August 17, 2020, at 5:00 PM CET.

GCS Large-Scale Projects are characterised by projects that require a large amount of computing time, meaning a minimum of 2 percent of a system’s annual production in terms of estimated availability, over a period of 12 months. Researchers at German universities and publicly funded German research institutions are eligible to apply.

Interested researchers can apply to gain access to GCS’ leading HPC systems:

  • High Performance Computing Center Stuttgart (HLRS): Hawk (HPE Apollo system)
  • Jülich Supercomputing Centre (JSC): JUWELS (Cluster Module and Booster Module)
  • Leibniz Supercomputing Centre, Garching (LRZ): SuperMUC-NG (Intel-Lenovo OceanCat platform)

For Hawk and SuperMUC-NG, large-scale projects are defined in terms of core-hours used. The minimum requirement of 2 percent of the system’s overall performance means that large-scale projects require at least 100 million core-hourson Hawk or at least 45 million core-hours on SuperMUC-NG. 

As JUWELS consists of two different modules with different hardware architectures, the minimal computing time requirements for GCS Large-Scale Projects are specified by the use of EFLOP (EFLOP: theoretical peak performance) with a minimum requirement of 45,000 EFLOP per year—summed up over all requested modules of JUWELS.

About GCS Large-Scale Projects: All large-scale projects go through a competitive review and resource allocation process established by the GCS. A "Call for Large-Scale Projects" is published by the Gauss Centre twice a year. Deadlines for calls are usually at the end of winter and at the end of summer of each year. An overview of the approved GCS Large-Scale Projects is available at
