GCS Grants Hundreds of Millions of Computing Core Hours to Leading National Science Projects


Berlin/Germany, July 29, 2013 – Computing time utilisation on the three Tier-0 supercomputers of the Gauss Centre for Supercomputing (GCS) has started for 14 new national research projects which were granted access to the HPC resources of GCS in the context of its latest “Call for Large-Scale Projects”–projects that require millions of core hours of computing run time. The 9th edition of GCS’s call, which closed in spring 2013, saw a record-breaking number of computing hours allocated: a total of 683.7 million were granted to 14 research activities which passed the strict qualification criteria set by the GCS Steering Committee. The largest allocations received projects in the fields of Quantum Chromo-Dynamics/QCD (73M core hours), Astrophysics (64M core hours), and Scientific Engineering (53M core hours).

The just started large-scale projects are allotted to the three GCS high performance computing systems Hermit of High Performance Computing Center Stuttgart (HLRS), JUQUEEN of Jülich Supercomputing Centre (JSC), and SuperMUC of Leibniz Supercomputing Centre in Garching near Munich (LRZ). All three GCS supercomputers provide Petaflops computing performance (1 Petaflops = 1 Quadrillion floating point operations per second or: a 1 with 15 zeros) and are of complementary system design and architecture to optimally respond to the needs of the researchers, developers and engineers. Computing resources for the projects of 9th GCS call are available to the users until the end of April 2014.

“We are proud to see the number of applications for large-scale projects steadily rise ever since the inauguration of GCS in 2007,” affirms Prof. Dr.-Ing. Siegfried Wagner, Chairman of the GCS Steering Committee. “The ultimate goal of GCS is to offer world-class HPC resources to aid in scientific computing for Germany as well as Europe. We are in the favourable position to do exactly this as we, since 2012, have petascale supercomputers installed in all of our three GCS member centres. Yet, at times we still struggle to fulfil the research community’s ever increasing demand for computing power in their quest of answers to scientific challenges–in some cases we cannot even supply the need,“ adds Prof. Wagner in consideration of the fact that for its 9th call GCS received requests for over 1,086 million core hours of computing time but could accommodate only two thirds of the applications, primarily for lack of computing resources.

Computing time allocations for large-scale projects are dispersed based on scientific criteria and their technical feasibility through independent reviewers in a peer-review process, led by the GCS Steering Committee.

The 9th GCS Call for Large-Scale Projects saw the largest individual allotments of computing hours granted to the following projects:

  1. QCD Thermodynamics Towards Finite Chemical Potentials (Prof. Dr. Zoltán Fodor, Theoretical Particle Physics of Bergische Universität Wuppertal)
    73M core hours on JUQUEEN of Jülich Supercomputing Centre (JSC)

  2. Self-Consistent High-Resolution 3D Simulations of Core-Collapse Supernova Explosions (Dr. Hans-Thomas Janka, Max-Planck-Institute for Astrophysics, Garching near Munich)
    64M core hours on SuperMUC of Leibniz Supercomputing Centre, Garching near Munich

  3. Simulation of Fluid-Particle Interaction in Turbulent Flows Including Conjugate Heat Transfer (Dr.-Ing. Matthias Meinke, Institute of Aerodynamics, Chair of Fluid Mechanics and Institute of Aerodynamics of RWTH Aachen)
    53M core hours on Hermit of High Performance Computing Center Stuttgart

About GCS Large Scale Projects: Per the mission of the Gauss Centre for Supercomputing, all scientists and researchers in Germany have access to the petascale HPC systems of Germany’s leading supercomputing institution. Projects are classified as "large-scale" if they require more than 2% of the available CPU cycles over one year on a GCS member centre’s high-end system. Computing time on the GCS systems is allocated by the GCS Steering Committee to scientifically leading, ground-breaking projects which deal with complex, demanding, and innovative simulations that would not be possible without the GCS petascale infrastructure. The projects are evaluated via a strict peer-review process on the basis of the project’s scientific and technical excellence.

About GCS:

The Gauss Centre for Supercomputing (GCS) combines the three national supercomputing centres HLRS (High Performance Computing Center Stuttgart), JSC (Jülich Supercomputing Centre), and LRZ (Leibniz Supercomputing Centre, Garching near Munich) into Germany’s Tier-0 supercomputing institution. Concertedly, the three centres provide the largest and most powerful supercomputer infrastructure in Europe to serve a wide range of industrial and research activities in various disciplines. They also provide top-class training and education for the national as well as the European High Performance Computing (HPC) community. GCS is the German member of PRACE (Partnership for Advance Computing in Europe), an international non-profit association consisting of 25 member countries, whose representative organizations create a pan-European supercomputing infrastructure, providing access to computing and data management resources and services for large-scale scientific and engineering applications at the highest performance level.

GCS is jointly funded by the German Federal Ministry of Education and Research and the federal states of Baden-Württemberg, Bavaria and North Rhine-Westphalia.

GCS has its headquarters in Berlin/Germany.
