GCS Awards 1358 Million Computing Core Hours to Research Projects

gcsToday the Gauss Centre for Supercomputing in Germany announced awards from the 14th Call for Large-Scale Projects. GCS says it achieved new All-Time Highs in various categories with 1358 million awarded core hours of compute time. The granted computing time will be divided between a hitherto unachieved number of 19 national outstanding scientific large-scale projects from the fields of Aerodynamics and Fluid Dynamics, Astrophysics, Biology and Life Sciences, Chemistry, Climate and Meteorology, Elementary Particle Physics, Material Sciences, and Theoretical Chemistry.

In addition, the assignment of 200 million core hours of compute time on the Hazel Hen supercomputer at HLRS was awarded to a research project by the Institute of Aerodynamics (AIA) of the RWTH Aachen University, means a new record amount of core hours allocated to an individual scientific simulation project.

For its 14th Call for Large-Scale Projects the GCS received a total of 24 applications, which sets yet another new record. 1903 million core hours of compute time were requested – an amount also marking a new all-time high in the history of GCS. 19 national computational science projects met the strict GCS large-scale project qualification criteria and were awarded computing time on the GCS supercomputers Hazel Hen of HLRS, JUQUEEN of JSC (Jülich Supercomputing Centre), and SuperMUC of LRZ (Leibniz Supercomputing Centre, Garching near Munich). The national researchers whose projects were selected will have access to these GCS high-performance computing (HPC) resources as of immediately for a period of 12 months.

“The ever growing number of applications for GCS large-scale projects plus the steady rise in the requested amount of computing core hours per individual project confirm the growing demand for high-performance computing,“ said Professor Dr.-Ing. Siegfried Wagner, Chairman of the GCS Scientific Steering Committee. “It is rewarding to note that the services and support provided by the GCS centres pay off: The HPC expertise acquired by our users puts them in a position to run applications scaling over tens or even hundreds of thousands of compute cores as provided by the GCS supercomputers. Availability creates demand, and the demand for computing time on our petascale HPC systems remains unbroken—as is the request for the availability of even more powerful HPC technologies. There is just no end of this trend in sight.”

With the 14th GCS Large-Scale Call, the largest individual allotments of computing core hours per scientific field were granted to the following projects:

Aerodynamics/Scientific Engineering:

  • 200 Mill core hours on Hazel Hen of HLRS for a project under leadership of Dr. Matthias Meinke (Institute of Aerodynamics, RWTH Aachen University)


  • 44 Mill core hours on SuperMUC of LRZ for a project under leadership of Prof. Dr. Ralf Klessen (Zentrum für Astronomie, Universität Heidelberg)

Biology and Life Sciences:

  • 84.3 Mill core hours on SuperMUC of LRZ for a project under leadership of Prof. Dr. Helmut Grubmüller (Max Planck Institut für Biophysikalische Chemie, Göttingen


  • 50 Mill core hours on JUQUEEN of JSC for a project under leadership of Prof. Dr. Dominik Marx (Lehrstuhl für Theoretische Chemie, Ruhr-Universität Bochum)

Elementary Particle Physics:

  • 84 Mill core hours divided between JUQUEEN of JSC (70 mill core hours) and SuperMUC of LRZ (14 Mill core hours) for a project under leadership of Dr. Rainer Sommer (DESY Zeuthen)

Material Sciences:

  • 35 Mill core hours on JUQUEEN of JSC for a project under leadership of Dr. Robert O. Jones (Peter-Grünberg-Institut 1, Forschungszentrum Jülich)


  • 88 Mill core hours on SuperMUC of LRZ for a project under leadership of Prof. Dr. Ralf Ludwig (Department of Geography, Ludwig-Maximilians-Universität München)

Computing time allocations for GCS Large-Scale Projects are granted based on scientific criteria and their technical feasibility through independent reviewers in a peer-review process led by the GCS Scientific Steering Committee. Computing time is available for a period of 12 months.
