LRZ to Deploy HPE’s Cray CS500 System with Arm Fujitsu A64FX Processors

June 23, 2020

GARCHING, Germany, June 23, 2020 —  The Leibniz Supercomputing Centre (LRZ) will extend its testbed program using HPE’s Cray CS500 system with Fujitsu A64FX processors that are based on Arm architecture. Integrating the technologies in early autumn, the institute of the Bavarian Academy of Sciences and Humanities will be the first academic computing centre in the European Union to offer this innovative hardware for its users to explore.

The Fujitsu A64FX Arm v8.2-SVE server.

HPE’s Cray CS500 system is based on the same Fujitsu A64FX processor used in the recently installed Japanese high-performance computer Fugaku–currently #1 on the global Top500 list–and is a central asset for the LRZ testbed program and its system known as BEAST (Bavarian Energy, Architecture and Software Testbed). The Arm-based architecture in the Fujitsu processors, integrated by Hewlett Packard Enterprise (HPE) will offer unique pathways for traditional modelling and simulation tasks while being equally suitable for data analytics, machine learning and artificial intelligence workloads. It will be available to core academic partners and select projects as well as next-generation HPC practitioners. HPE’s Cray CS500 system features the Cray Programming Environment, a fully integrated software suite that maximizes programmer productivity and application performance.

“As a world-class academic supercomputing centre, it is one of our core tasks to explore new and diverse architectures within our Future Computing Program. Together with our core partners, we look forward to exploring the capabilities of this technology and the benefit it brings to our users’ science – especially in the area of HPC and AI”, says Dieter Kranzlmüller, Director of the LRZ.

“HPC plays an increasingly critical role to meet key societal and economic challenges in areas like medicine, climate change, and risk management. We are committed to advancing HPC technologies by developing diverse architectures to support any workload need,” said Bill Mannel, Vice President and General Manager, HPC, Hewlett Packard Enteprise. “We look forward to working with the Leibniz Supercomputing Centre to explore how alternative architectures can enable new HPC applications to bolster research and innovation, while improving performance and efficiency.”

Exploring diverse architectures for Future Computing

Each of the Fujitsu A64FX Arm-based processors will be equipped with 32GB of second-generation high bandwidth memory (HBM2). The servers are connected by an EDR-Infiniband network. The system comes with an Open-Source (GCC/LLVM) software stack as well as a Cray Programming Environment supporting the vectorised processor units.

HPE’s Cray CS500 offers LRZ users and HPC specialists evaluation and research opportunities for the processors’ performance on real-world
applications and in comparative studies to both regular CPUs and GPUs. As a pioneering centre for energy-efficient HPC systems and data centre infrastructure, LRZ is also highly interested in evaluating the performance per watt the system can deliver.

“The Scalable Vector Extension (SVE) architecture, the high memory bandwidth with HBM2, and the Cray Compiler Environment and software stack are a few of the things we’re excited to explore and better understand in support of our users and their scientific work,” says Josef Weidendorfer, team lead Future Computing at LRZ.

About the LRZ

The Leibniz Supercomputing Centre (LRZ) proudly stands at the forefront of its field as a worldclass IT service and computing user facility serving Munich’s top universities as well as research institutions in Bavaria, Germany and Europe. As an institute of the Bavarian Academy of Sciences and Humanities, LRZ has provided a robust, holistic IT infrastructure for its users throughout the scientific community for nearly sixty years. It offers the complete range of resources, services, consulting and support–from email, web servers and Internet access to virtual machines, cloud solutions, data storage and the Munich Scientific Network (MWN). Home to SuperMUC-NG, LRZ is part of Germany’s Gauss Centre for Supercomputing (GCS) and serves as part of the nation’s backbone for the advanced research and discovery possible through high-performance computing (HPC). In addition to current systems, LRZ’s Future Computing Group focuses on the evaluation of emerging Exascale-class architectures and technologies, development of highly scalable machine learning and artificial intelligence applications, and system integration of quantum acceleration with supercomputing systems.
