Leibniz Supercomputing Centre Builds A Powerful World First

The Leibniz Supercomputing Centre uses the Intel® Xeon® processor E5 family to build one of the world’s most powerful computers

Germany’s Leibniz Supercomputing Centre (LRZ) provides computing facilities for Munich’s universities and the Bavarian Academy of Science and Humanities. As part of the Gauss Centre for Supercomputing (GCS), it is also a national centre for high-performance computing (HPC) and a leading supercomputing centre for the Partnership for Advanced Computing in Europe (PRACE), an affiliation of European organizations dedicated to operating European supercomputing infrastructure and to promote HPC usage throughout Europe. It is operating a new general purpose HPC platform with over 155,000 Intel® Xeon® processor E5 family cores. Called SuperMUC*, the HPC platform is No. 4 in the TOP500 Supercomputer rankings and is the largest Intel-based computer in the world.

Challenges
• New platform. To remain competitive and provide European researchers with state-ofthe-art compute power, LRZ needed a new HPC platform.
• Three priorities. Application performance, energy efficiency, and general all-purpose computing were its three main criteria.

Solutions
• Detailed search. LRZ considered all major HPC options including a variety of architecture choices.
• Benchmarking. Following benchmarking of eight varied HPC applications and several benchmark kernels, it chose a liquid-cooled IBM iDataPlex* system powered by over 155,000 Intel Xeon processor E5 family cores.

Impact
• Largest supercomputer. Called SuperMUC, the platform delivers three petaflops of computing performance and is the largest Intel processor-powered supercomputer in the world.
• Performance surge. SuperMUC delivers a 50x performance increase compared to the pre-existing HPC platform and a 16x performance increase per watt.
• Cool inside. A specially developed liquid cooling system ensures free cooling as long as the outside temperature remains below 50° Celsius.
