Leibniz-Rechenzentrum
The Leibniz -Rechenzentrum ( LRZ ) of the Bavarian Academy of Sciences in Garching near Munich, is the central data center of Munich's two state universities Ludwig- Maximilians- University of Munich and Technical University of Munich, the Academy of Sciences, the University of Applied Sciences Munich University of Applied Sciences Fachhochschule Rosenheim. Carrier is the Bavarian Academy of Sciences, the LRZ is organizationally assigned to the " Commission for computer science ".
To him more than 150 employees. The LRZ operates high and very high performance computers and the Munich Scientific Network.
The LRZ was founded in 1962 with the name " Electronic Computing Committee "; the present name dates back to Gottfried Wilhelm Leibniz. Despite its name, the LRZ is not a member of the Leibniz Association. Organizes the LRZ is, among other things in the Gauss Centre for Supercomputing (GCS ).
In 2006, the LRZ Munich moved in Garching near Munich. The new site is organized in the Institute building with approximately 5700 m² of floor space, the computer cube with about 5000 m² and a lecture hall and seminar building one. The construction costs were approximately 45.2 million euros.
High-performance computing
The High Performance Computing Bavaria I ( HLRB -I) was based on a Hitachi SR8000-F1/168: 1512 Power -3 processors with 375 MHz divided into 168 SMP nodes, each with 9 CPUs ( 8 usable), 2 petaflop / s peak performance ( 1.7 petaflop / s Linpack ), 1.4 TB of memory, 10 terabytes of disk space. The operating system HI -UX was used. When commissioning in 2000, he had already reached in the first stage with 112 nodes 1029 GFlop / s ( Linpack ), making it the fastest computer in Europe. In 2002 he reached the final stage number 14 in the TOP500 and was the fastest computer in Germany. In June 2006, he was shut down because of the acquisition of HLRB -II.
The High Performance Computing Bayern II ( HLRB -II) based on an SGI Altix 4700 with 9728 Intel Itanium 2 processor cores in 19 SMP nodes, each with 512 CPU cores, 62.3 petaflop / s peak performance ( Rpeak ), 39 terabytes of memory, and 600 terabytes of disk space.
A Linux cluster with 500 processors in 236 nodes, 3.0 petaflop / s equipped Peak Performance, 1.8 TB of memory, 25.5 TB of disk space. The individual nodes consist of several computers from a 32- bit uniprocessor system with a Pentium 4 64 -bit dual processor, two Opterons to an SGI Altix 3700 with 128 Itanium 2 CPUs.
In July 2009, the data center expansion to a second high-performance computers, SuperMUC decided. Here, a second, likewise cube -like structure is built directly on the HLRB II, completed in 2006, in which the computer is installed. The cost of the expansion will be 135 million euros and will be borne by the Federal Government and the Free State of Bavaria. On July 20, 2012 SuperMUC was officially put into operation during a ceremony marking the 50th birthday of LRZ with Federal Minister Annette Schavan and the Bavarian Minister of Science Wolfgang Heubisch. SuperMUC at this time with more than 3 petaflops computing power of the fourth-fastest computer in the world and the fastest computer in Europe.
The LRZ also participates in the AstroGrid -D. Furthermore hosted the hardware for the LCG Tier 2 of the Ludwig- Maximilians- University of the LRZ.
