TOP500: Gauss Centre for Supercomputing Continues to Play Leading Role in High Performance Computing

Berlin/Germany, June 30, 2014 – The Gauss Centre for Supercomputing (GCS) resumes its role as a global player in High Performance Computing (HPC). In the latest TOP500 rankings, released at the International Supercomputing Conference 2014 in Leipzig/Germany, HPC system JUQUEEN of GCS member centre Jülich Supercomputing Centre (JSC) defended position 8 in the renown list with its peak performance (Rpeak) of 5.872 Petaflops, and HPC system SuperMUC (Rpeak 3.185 PFlops) of the Leibniz Supercomputing Centre Garching/Munich (LRZ) now holds position 12 in the latest TOP500.

The now captured positions of the GCS supercomputers are especially worth mentioning as neither system underwent any hardware upgrades in the last 18 months. Both LRZ’s SuperMUC as well as the supercomputing infrastructure at the High Performance Computing Centre Stuttgart (HLRS) will see system expansions in the forthcoming year. To date, HLRS’s supercomputer Hermit holds a very strong 3rd position in the TOP500-sublist for industrially used supercomputers with its peak performance of 1.09 Petaflops.

SuperMUC: Ranked 6th on New HPCG Benchmark

Special attention was paid at ISC’14 to a brand new gender of HPC benchmark, the HPCG (High Performance Conjugate Gradient). While the Linpack benchmark, which serves as metrics for the TOP500, measures the speed and efficiency of linear equation calculations of a system, the HPCG benchmark tries to reflect changed customer requirements. It does not focus on raw CPU performance but stresses the system balance, e. g. floating point and communication bandwidth and latency, and it tightens the focus on messaging, memory, and parallelization—parameters that add up to an “averaged” yet from the users’ perspective more beneficial and thus more important system performance.

Once again, GCS centre Leibniz Supercomputing Centre acted as pioneer in these customer oriented efforts. It was one of only 15 supercomputing centres world wide to submit data for the HPCG benchmark. With a performance of 83.3 Teraflops, showing an efficiency rate of 2.9 per cent of the peak system performance, SuperMUC at first go captured position 6 on the HPCG ranking. “With its ability to execute HPCG extremely efficiently, SuperMUC demonstrates once again how powerful the system is in supporting many areas of science,“ adds Professor Bode, Director of the Leibniz Supercomputing Centre. „We are proud to see this reflected in the excellent HPCG position with SuperMUC being number 6 in the world.“

The HPCG benchmark was initiated by Linpack co-founder Professor Dr. Jack Dongarra (University of Tennessee, USA) well over a year ago.

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 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.
