Leibniz Supercomputing Centre Hosts Europe’s Most Powerful Supercomputer

SuperMUC Ranks 4th on TOP500 List With a Peak Performance of ~3 Petaflop/s

Berlin/Germany, June 18, 2012 – The Leibniz Supercomputing Centre in Garching near Munich, one of GCS’s three national supercomputing centres, hosts one of the world’s most powerful HPC system to date. A peak performance of about 3 Petaflop/s (3 quadrillion floating point operations per second), achieved on the Linpack benchmark, positioned the newly installed SuperMUC on rank 4 on the newly released TOP500 list of the world’s fastest supercomputers. With this result, SuperMUC currently holds the title as fastest HPC system in all Europe.

SuperMUC, a System X iDataPlex from IBM, has been designed as general purpose HPC system allowing an exceptionally versatile deployment. The applications running on LRZ’s new HPC system cover a wide spectrum of science and research, ranging from medical
applications to astrophysics. “SuperMUC is extraordinary user friendly”, stresses Professor Dr. Arndt Bode, LRZ’s Chairman. “Since we run more than 100 different applications per year on our system, an instruction set allowing easy adaption of user software was a core
requirement on the system architecture”.

SuperMUC is equipped with more than 155,000 processor cores, 330+ Terabytes of main memory are available for data processing. These data can be transferred between nodes via a non-blocking InfiniBand network with fat tree topology. In addition, up to 10 Petabytes of data can intermediately be stored in parallel file systems based on IBM’s GPFS. For permanent storage of user data like program source code, input data etc., a storage solution of NetApp with more than 4 Petabytes capacity is available, renowned for its high reliability. Furthermore, magnetic tape libraries with a capacity of 16.5 Petabytes are available for longterm archiving of data.

Not Only Fast But Also Energy Efficient

While SuperMUC ranks as the 4th fastest HPC system world wide, it claims fame for being the number 1 on the TOP500 list in terms of energy-efficiency. With a PUE* value of 1.1, SuperMUC is on the forefront of Green IT efforts (Greengineering) in data centres. A revolutionary new form of hot-water cooling technology implemented by IBM takes credit for this achievement. The Intel processors and the system software delivered to LRZ offer further opportunities to save energy. By all these measures, the total energy consumption could be drastically reduced to crunching only 0.86 gigaflops for every watt consumed – a currently unmatched ratio. In acknowledgement of these environment-friendly focused efforts, the LRZ only recently was awarded the “Deutscher Rechenzentrumspreis 2012” in the category “Energy and Resource Efficient Data Centres” ( Adds Prof. Bode: “Energy efficiency is a key component of today’s computing devices – from smart phones to supercomputers. Public research institutions such as LRZ should and can act as pioneers in this field, and with SuperMUC we deliver proof that energy consumption in data centres can significantly be reduced. This is of major importance especially given the fact, that as of this year all state-funded institutions across Germany are required to purchase 100% sustainable energy for all electricity consumed.“

* PUE is the ratio of total amount of power used by a computer data center facility to the power delivered to computing equipment.

SuperMUC is a contribution of the Gauss Centre for Supercomputing (GCS) to the German and European High Performance Computing PRACE (Partnership for Advanced Computing in Europe). Both SuperMUC and the associated extension of the LRZ buildings, which
include a new visualization centre, were co-funded by the Federal Government of Germany (BMBF/German Federal Ministry of Education and Research) and the Free State of Bavaria. The operational costs are covered exclusively by the Free State of Bavaria. Accompanying projects are funded by the European Union, the BMBF, as well as via additional third-party funds.

Inauguration ceremony on July 20th, 2012

The official transfer of ownership of SuperMUC from IBM to LRZ as well as the formal launch of operation will take place on July 20th 2012, jointly with the 50th anniversary of the Leibniz Supercomputing Centre of the Bavarian Academy of Sciences.

About GCS:

The Gauss Centre for Supercomputing (GCS) consolidates the three national supercomputing centres HLRS (High Performance Computing Center Stuttgart), JSC (Jülich Supercomputing Centre), and LRZ (Leibniz Supercomputing Centre, Garching) into Germany’s Tier-0 Supercomputing institution. Concertedly, the three centres provide the largest and most powerful supercomputer infrastructure in Europe to serve a wide range of industrial and research activities in various disciplines. They also provide top-class training and education for the national as well as the European High Performance Computing (HPC) community. GCS is the German member of PRACE (Partnership for Advance Computing in Europe), an international non-profit association consisting of 24 member countries, whose representative organizations create a pan-European supercomputing infrastructure, providing access to computing and data management resources and services for largescale scientific and engineering applications at the highest performance level.

GCS has its headquarters in Berlin/Germany.
