GCS offers the most powerful supercomputing infrastructure in Europe, aimed at serving a broad range of scientific and industrial research activities in various disciplines.
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.
The High-Performance Computing Center Stuttgart (HLRS) hosts an HPE Apollo system named Hawk. The system officially came online in 2020. The machine features 720,896 compute cores and has a theoretical peak performance of 26 petaflops. The system is designed to serve a wide range of sciences, including the life sciences, energy and environmental sciences, high-energy physics, and astrophysics, but places a special empahsis on supporting the computational and scientific engineering communities in academia and industry.
After the Cluster Module of the Jülich Supercomputing Centre’s (JSC's) HPC system JUWELS (Jülich Wizard for European Leadership Science) went into operation in July 2018, the Booster Module is currently being installed and will complement the cluster system. JUWELS’ 2511 nodes on the Cluster Module are equipped with dual-socket Intel-Skylake Platinum 8168 CPUs. In addition, 56 Dual Intel Xeon Gold 6148 nodes are equipped with 4 additional NVIDIA Volta V100 GPUs yielding a total performance of about 12 petaflops. The JUWELS Booster Module comprises 936 nodes each equipped with two AMD EPYC Rome 7402 CPUs with 512 GB DDR memory and 4 NVIDIA Ampere A100 GPUs. With the Booster Module, JUWELS computing power increases sevenfold compared to the first installation phase, providing in total 87 petaflops to its users.
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.
