The SuperMUC is the name of a new supercomputer of the Leibniz-Rechenzentrum (Leibniz Supercomputing Centre) in Garching near Munich which will provide a sustained computing power in the petaflop/s regime.

SuperMUC will be the successor of the Höchstleistungsrechner Bayern II (HLRB II). The Leibniz Supercomputing Centre will become a European centre for supercomputing. In order to house the extended hardware, the infrastructure of the Leibniz Supercomputing Centre will be more than doubled. Additional buildings for the hardware and office space are under construction. SuperMUC was named the second fastest supercomputer in Europe and is at position 6 in the TOP500 list at the November 12, 2012 International Supercomputing Conference[1] in Hamburg, Germany.[2] It is also the fastest Intel-compatible system in the world.

The new supercomputer will be run by the Germany's Bavarian Academy of Science's Leibniz Supercomputing Centre and will be available for European researchers to use to probe the frontiers of medicine, astrophysics and quantum chromodynamics and other scientific disciplines such as computational fluid dynamics, computational chemistry, life sciences, genome analysis and earth quake simulations. It will be fully operational in summer 2012. (The MUC suffix is borrowed from the Munich airport code).


The SuperMUC will have 18,432 Intel Xeon Sandy Bridge-EP processors running in IBM System x iDataPlex servers with a total of 147,456 cores and a peak performance of about 3 petaFLOPS (3 × 1015 FLOPS). The main memory will be 288 terabytes (288 × 1012 bytes) together with 12 petabytes (12 × 1015 bytes) of hard disk space based on the IBM General Parallel File System (GPFS). It will also use a new form of cooling that IBM developed, called Aquasar, that uses hot water to cool the processors, a design that should cut cooling electricity usage by 40 percent, IBM claims.[3][4]

SuperMUC will be connected to powerful visualization systems, which consists of a large 4K stereoscopic powerwall as well as a 5-sided CAVE artificial virtual reality environment.
