AUSTIN, Tex., Nov. 19 — HPC system Hazel Hen of GCS member centre HLRS (High Performance Computing Center Stuttgart) is Europe’s fastest supercomputer on the High Performance Conjugate Gradient (HPCG) benchmark list. This was announced yesterday at the Supercomputing Conference 2015 in Austin, Texas. The newly created HPCG benchmark represents the behavior of HPC systems running real applications. Hazel Hen, a CRAY XC40 system, captured a strong position 6 by delivering a performance of 138 Teraflops and with this took the European lead amongst the world’s fastest supercomputers.
The HPCG benchmark has recently enjoyed growing attention in the HPC community as it tries to reflect changed customer requirements. It has been developed to provide a benchmark for performance of the fastest supercomputers measured in real applications. While the Linpack benchmark, which serves as metrics for the well known TOP500, measures the speed and efficiency of full matrix linear equation calculations of a system, the HPCG benchmark does not focus on raw CPU performance but stresses the system balance, e. g. floating point operations versus bandwidth and latency of the memory system and the communication network. In addition, it tightens the focus on messaging, memory, and parallelization. All these parameters add up to an “averaged” yet from the users’ perspective more beneficial and thus more important system performance.
“Being listed in the top-10 of the TOP500 is an honor for us. However, our focus at HLRS has always been on user performance. Everything else comes second,” stresses Prof. Michael M. Resch, Director of the HLRS. “As a consequence, we are all the more delighted to take the lead in Europe for this realistic application benchmark. This is the result of the work of many people at HLRS, and we would like to thank all colleagues from Cray and from the University of Stuttgart as well as the state of Baden-Württemberg and the Federal Government of Germany for their continued and ongoing support. Today, we have shown that our focus on the users pays off.”
In addition to the HLRS, the other two GCS member centres – Jülich Supercomputing Centre (JSC) and Leibniz Supercomputing Center (LRZ) at Garching near Munich – also undertook the efforts to put their systems through a HPCG benchmark test. With JSC system JUQUEEN (95,5 Teraflops) on position 11 and LRZ system SuperMUC (83.3 Teraflops) ranked 13th, all three GCS member centres achieved outstanding results and delivered proof about their focus on and commitment to user performance. To date, the HPCS benchmark list encompasses 63 HPC systems world-wide with its number steadily growing.
The High Performance Computing Center Stuttgart (HLRS) of the University of Stuttgart is one of the three German supercomputer institutions forming the national Gauss Centre for Supercomputing. HLRS supports German and pan-European researchers as well as industrial users with leading-edge supercomputing technology. It’s Cray XC40 system complements the system architectures provided by the other two GCS member centres Leibniz Supercomputing Centre Garching/Munich (IBM System X iDataPlex plus Lenovo NeXtScale WCT system) and Jülich Supercomputing Centre (IBM BlueGene/Q).

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. www.gauss-centre.eu
