Usage of SuperMUC-NG - supercomputer

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 311,000 cores and a peak performance of more than 26.9 Petaflop/s (=1015 Floating Point Operations per second), it is one of the fastest supercomputers in the world.

SuperMUC-NG is available to all European researchers of the PRACE member states to expand the frontiers of science and engineering.

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).

A separate application procedure for academic users from Germany and the European PRACE member states must be completed to gain access.

In order to carry out sophisticated numerical simulations in the natural and engineering sciences, the LRZ provides more powerful supercomputers and the software necessary for their use. The LRZ aims to ensure that such computers are among the most powerful systems in the world, at least at the time of procurement. Typical features of these supercomputers are a large number of networked processors that access fast, shared file systems and a very large shared main memory. The supercomputer at the LRZ can be used by scientists all over Germany and researchers of the PRACE member states, but the prerequisite is that an evaluation procedure is successfully completed. In addition to operating the computer, the LRZ offers extensive support in using the computers and optimizing the programs running on them.
