High Performance Computer

SuperMUC-NG is the name of the high-end supercomputer at the Leibniz-Rechenzentrum (Leibniz Supercomputing Centre) in Garching near Munich (the MUC suffix is borrowed from the Munich airport code). With more than 241,000 cores and a combined peak performance of the two installation phases of more than 6.8 Petaflop/s (=10¹⁵ Floating Point Operations per second), it is one of the fastest supercomputers in the world.

LRZ's target for the architecture is a combination of a large number of thin nodes and a smaller number of fat compute nodes with 96 GByte (thin nodes) and 768 GByte (fat nodes) of memory, respectively. The network interconnect between the nodes allows excellent scaling of parallel applications up to the level of more than 10,000 tasks.

SuperMUC-NG consists of 6 Thin Node Islands based on Intel Skylake Xeon Platinum 8174 processor technology, and one Fat Node Island. Each Thin Node Island contains 50,688 cores and the Fat Node Island contains 6912 cores. All compute nodes within an individual Island are connected via a fully non-blocking OmniPath network. Above the Island level, the pruned interconnect enables a bi-directional bi-section bandwidth ratio of 3,75:1 (intra-Island / inter-Island).

• Status reports for supercomputers: doku.lrz.de/reporting-obligations-on-supermuc-ng-11482619.html
• Regular maintenance lasting 2-5 days takes place once or twice a year and is announced at least 14 calendar days in advance.
• A service availability of at least 95% is aimed for. Regular maintenance times are not taken into account.

A separate application procedure for academic users from Germany must be completed in order to gain access.

• Usage and operating regulations for the supercomputer at the Leibniz Supercomputing Centre (SuperMUC-NG): www.lrz.de/services/compute/supermuc/regulations/Nutzungs-Betriebsordnung_SuperMUC.pdf
• Export control regulations: High-performance computers are considered dual-use goods. The high-performance computers themselves, but also their use, are therefore subject to restrictions arising from national, EU and, where applicable, US law. Each user and the project manager/master user is responsible for compliance with the legal provisions.
