Results of the 16th GCS Large Scale Call

GCS Supports National Scientific Large-Scale Simulation Projects With More Than 1 Billion Computing Core Hours


Berlin/Germany, November 11, 2016 – National scientists continue to exploit the petascale computing power offered by the GCS centres HLRS (High Performance Computing Center Stuttgart), JSC (Jülich Supercomputing Centre), and LRZ (Leibniz Supercomputing Centre, Garching/Munich) for large-scale simulation projects. With the 16th GCS Large-Scale Call, the scientific steering committee of the Gauss Centre for Supercomputing (GCS) approved the allocation of in sum 1,068 million core hours of computing time to 17 scientifically outstanding German research activities. The supported projects come from the fields of Astrophysics, Chemistry, Earth and Environment, Elementary Particle Physics, Life Sciences, Materials Sciences, and Scientific Engineering.

Among the 17 projects of the 16th GCS Large-Scale Call, which fulfilled the strong qualification criteria overseen by the GCS Steering Committee, one research activity will benefit in particular from the fact that through the GCS researchers can access complementary HPC system architectures simultaneously. Prof. Dr. Rainer Sommer from DESY Zeuthen will use both GCS HPC systems JUQUEEN, hosted at JSC, and SuperMUC of the LRZ for his project "Non-perturbative Heavy Quark Effective Theory and the strong coupling". By splitting the computation tasks between these two HPC systems, Professor Sommer and his team will make sure to fully leverage JUQUEEN's IBM BlueGene/Q architecture and the Intel Xeon processor architecture of SuperMUC to achieve optimal results

"With its three national HPC centres each featuring petascale HPC systems, GCS is in the unique position not only to offer complementary system architectures of world-class but also to provide best possible HPC services and support to its different user communities," explains Prof. Dr. Dietmar Kröner of the University of Freiburg, Chairman of the GCS Steering Committee. "Our complementary, controlled approach to serve the wide field of scientific as well as industrial HPC users is a prime underlying reason why HPC supported national research activities are soaring. The demand by our users for more computing time and/or even more HPC power remains unbroken, and we are looking forward to serve our scientific and industrial user community even better in the years to come".

For all projects approved with the 16th GCS Large-Scale Call, researchers will have access to the GCS HPC systems Hazel Hen of HLRS, JUQUEEN of JSC, and SuperMUC of LRZ for a period of 12 months, starting immediately.

About GCS Large-Scale Projects In accordance with the mission of the Gauss Centre for Super-computing, all scientists and researchers in Germany are eligible to apply for computing time on the petascale HPC systems of Germany’s leading supercomputing institution. Projects are classified as "large-scale" if they require more than 35 million core-hours in one year on a GCS member centre's high-end system. Computing time on the GCS systems is allocated by the GCS Scientific 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 supercomputing infrastructure in all of 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.
