120 million core hours on CRAY XE6 Hermit allocated to 3 awardees of the PRACE 4th Call for Proposals

PRACE awarded 120 million core hours on the brand new CRAY XE6 Hermit supercomputer at HLRS@GCS in Germany to three successful projects submitted to the 4th PRACE Call for Proposals. Two awardees will be using their allocated core hours for research in the field of Engineering & Energy; the third one comes from the field of Chemistry and Materials.

Hermit was officially inaugurated as the new German national supercomputer in February 2012. Being one of the fastest supercomputers in the world, Hermit has a performance of more than 1 Petaflop/s (1 quadrillion computing operations per second) and will be upgraded to 4 to 5 Petaflop/s in 2013. Hermit is the first and largest system in Europe to use Cray XE6 Supercomputer technology and an AMD Interlagos-Processor.

For the PRACE Project Access 4th Call for Proposals on Tier-0 systems, 1136 million core hours on 5 Tier-0 machines were made available by PRACE hosting members. The peer review process for the project applications allocated 1134 million core hours to 43 proposals. Out of those 43 proposals, three were granted access to Hermit.

Quantum Monte Carlo simulation of hydrogen at high pressure.

Prof. Carlo Pierleoni of the University of L’ Aquila (Italy) will lead a project in the field of Chemistry and Engineering. His collaborators on this project are the University of Roma "Sapienza" (Italy) the Lawrence Livermore National Laboratory (USA), the University of Illinois at Urbana-Champain (USA), SISSA/ISAS (Italy) and CNRS/LPTMC (France). They will apply first principles simulation methods based on quantum Monte Carlo and density functional theory to elucidate the equilibrium properties and to explore superconductivity of hydrogen at high pressure. 24 million core hours on Hermit were allocated to this research.

Direct Numerical Simulation of the Flow in an Internal Combustion Engine.

Prof. Dr. Ing. Wolfgang Schröder of RWTH Aachen University - Institute of Aerodynamics (Germany) will lead a project in the field of Engineering and Energy. The central objective of this research project within the TMFB cluster is to analyze the flow field under real engine conditions. 72.7 million core hours on Hermit were allocated to this research.

Comprehensive ab initio simulations of turbulence in ITER-relevant fusion plasmas

Prof. Frank Jenko of the Max Planck Institute for Plasma Physics (IPP) - Tokamak Physics (Germany) will lead a project in the field of Engineering and Energy. His collaborators on this project are the Ecole Polytechnique Federale de Lausanne (Switzerland) and the Rechenzentrum der Max-Planck-Gesellschaft (Germany). Using the state-of-the-art plasma turbulence code GENE (, comprehensive global computations of actual ASDEX Upgrade and JET discharges involving realistic MHD equilibria, finite-beta effects, collisions, etc. will be performed, using experimental data as input. 23.3 million core hour on Hermit were allocated to this research.

About GCS The Gauss Centre for Supercomputing (GCS) consolidates the three national supercomputing centres HLRS (High Performance Computing Center Stuttgart), JSC (Jülich Supercomputing Centre), and LRZ (Leibniz Supercomputing Centre, Garching) into Germany’s Tier-0 Supercomputing institution. Concertedly, the three centres provide one of the largest and most powerful supercomputer infrastructures 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 has its headquarters in Berlin/Germany.

About HLRS The High Performance Computing Center Stuttgart (HLRS) of the University of Stuttgart supports researchers and industry with leading edge supercomputing technology. Compute Services are supplied to industrial partners like Porsche and Daimler through the public-private partnership of hww GmbH. Collaborative research with the automotive industry goes through the Automotive Simulation Center Stuttgart (ASCS). In European, national, and industrial projects HLRS conducts basic and applied research in HPC focusing on programming methods and applications.

About PRACE The Partnership for Advanced Computing in Europe (PRACE) is an international non-profit association with its seat in Brussels. The PRACE Research Infrastructure (RI) provides a persistent world-class High Performance Computing (HPC) service for scientists and researchers from academia and industry. The Implementation Phase of PRACE receives funding from the EU’s Seventh Framework Programme (FP7/2007-2013) under grant agreements n° RI-261557 and n° RI-283493.
