HPC SYSTEMS - PETASCALE PERFORMANCE

GCS offers the most powerful supercomputing infrastructure in Europe, aimed at serving a broad range of scientific and industrial research activities in various disciplines.

Supercomputing at the Leading Edge

Each GCS centre hosts a multi-petaflop supercomputing system, placing all three individual institutions among the most powerful computing centres in the world. With its combined performance, GCS provides the largest supercomputing infrastructure in all of Europe. The system architectures implemented at the three GCS centres are complementary in order to accomodate the broadest range of scientific disciplines. 

Hazel Hen of HLRS

The High-Performance Computing Center Stuttgart (HLRS) hosts a Cray XC40 system named Hazel Hen. The system officially came online in 2015. It features 185,088 compute cores and delivers a peak performance of 7.42 petaflops. Hazel Hen is designed to serve a wide range of sciences, including computational and scientific engineering, life sciences, energy and environmental sciences, high-energy physics, and astrophysics.

JUWELS of JSC

In July 2018, the first module of the Jülich Supercomputing Centre’s (JSC's) current HPC system JUWELS (Jülich Wizard for European Leadership Science) went into operation. JUWELS will ultimately consist of multiple, architecturally diverse but fully integrated modules designed for specific simulations and data science tasks.

JUWELS is a modular system that will be installed in several steps. The current cluster module (CPU) is equipped with about 2,500 dual-socket Intel Skylake Platinum 8168 nodes. About 2 percent of the nodes have an additional 4 NVIDIA Volta GPUs. The system’s theoretical peak is 12 petaflops. According to the TOP500 list, JUWELS delivers a Linpack performance of 6.2 petaflops.

SuperMUC-NG of LRZ

In September 2018, the Leibniz Supercomputing Centre’s (LRZ’s) latest edition to its series of SuperMUC supecomputers was officialy introduced: SuperMUC-NG (“next generation”). With its peak performance of 26.7 Petaflops—an almost fourfold increase of the computing power previously available at LRZ—SuperMUC-NG is currently the fastest supercomputer in Germany. It features an Intel-Lenovo OceanCat platform equipped with 6,336 compute nodes (more than 300,000 compute cores) with Intel Skylake processors and OmniPath interconnects, 700 terabytes of main memory, and 70 petabytes of disk storage.
