GCS Sets Records for Hours Delivered, User Participation in 17th Large-Scale Call


Berlin/Germany, May 15, 2017—The Gauss Centre for Supercomputing (GCS) approved 30 large-scale projects during the 17th call for large-scale proposals, set to run from May 1, 2017 to April 30, 2018. Combined, these projects received 2.1 billion core hours, marking the highest total ever delivered by the three GCS centres—the High Performance Computing Center Stuttgart (HLRS), Jülich Supercomputing Centre (JSC), and Leibniz Computing Centre of the Bavarian Academy of Sciences and Humanities (LRZ). In addition to delivering record-breaking allocation time, GCS also broke records in proposals received and number of allocations awarded.

GCS awards large-scale allocations to researchers studying earth and climate sciences, chemistry, particle physics, materials science, astrophysics, and scientific engineering, among other research areas of great importance to society.

Of the 30 projects, four were granted allocations exceeding 100 million core-hours—another first for GCS—speaking to users’ increasingly strong command of making the best possible use of the various GCS centres’ flagship supercomputers.

“As we continue to provide world-class computing resources and user support at our three GCS facilities, our user base continues to expand based on the wide variety of excellent proposals we receive during each successive large-scale call,” said Dr. Dietmar Kröner, University of Freiburg Professor and Chairman of the GCS Scientific Steering Committee. “We have tough decisions to make, as we only have so many core-hours per year, and the proposals continue to get better each year.”

Several of the largest allocations are benefiting from the variety of architectures offered through the three GCS centres.

A team led by Dr. Matthias Meinke of RWTH Aachen University received a total of 335 million core hours—250 million at HLRS and 85 million at JSC—for a project dedicated to understanding turbulence, one of the last major unsolved fluid dynamics problems. The team studies turbulence as it relates to jet engine dynamics, and its research is focused on creating quieter, safer, more fuel efficient jet engines.

A team of astrophysicists led by Dr. Hans-Thomas Janka of the Max Planck Institute for Astrophysics was granted 120 million core hours on LRZ’s SuperMUC system to simulate supernovas—the death and explosion of stars, and one of the main ways that heavy elements travel across the universe.

In previous allocations, the team was able to create one of the first first-principle simulations of a 3D supernova, and plans to expand its research to more accurately understand the volatile, dynamic processes that govern the formation of neutrinos and gravitational waves occurring after a supernova.

Supercomputing has become an indispensable tool in studying the smallest, most fundamental building blocks of matter known to man—the quarks and gluons that make up protons and neutrons, and, in turn, our world. A research group based at the Department of Theoretical Physics at the University of Wuppertal is benefitting from two separate allocations—one of which uses both HLRS and JSC resources, while the other is solely based at JSC—to more deeply understand the mysterious subatomic world:

Dr. Szabolcs Borsányi leads a project aiming to make the first-ever estimate of sheer viscosity of the quark-gluon plasma—a novel state of matter that exists only at extremely high temperatures, making it very hard to study experimentally. The project was granted 35 million core hours on JSC’s JUQUEEN.

Prof. Dr. Zoltán Fodor was granted 130 million core-hours on HLRS’s Hazel Hen and 78 million core-hours on JUQUEEN to support large-scale international experimental work being done at the Large Hadron Collider in Switzerland and the Relativistic Heavy Ion Collider in the United States. The team uses HPC to more fully understand phase transitions within quantum chromodynamics—the behaviour of subatomic particles under extreme pressure or temperature conditions.

About GCS Large-Scale Projects: In accordance with the GCS mission, all 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 are allocated more than 35 million core-hours in a given year at a GCS member centre’s high-end system. Computing time is allocated by the GCS Scientific Steering Committee to ground-breaking projects which seek solutions to long-standing complex science and engineering process that cannot be solved without access to world-leading computing systems. The projects are evaluated through 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 German national supercomputing centres HLRS (High Performance Computing Center Stuttgart), JSC (Jülich Supercomputing Centre), and LRZ (Leibniz Supercomputing Centre, Garching near Munich) into Germany’s integrated Tier-0 supercomputing institution. Together, the three centres provide the largest, most powerful supercomputing infrastructure in all of Europe to serve a wide range of academic and industrial research activities in various disciplines. They also provide top-tier 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 Advanced Computing in Europe), an international non-profit association consisting of 24 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. It is headquartered in Berlin, Germany.
